# How to Mod Old Games to Run on Modern PCs
Old video games hold a special place in many gamers’ hearts, but running them on modern PCs can be a challenge due to compatibility issues, outdated graphics, and missing features. Fortunately, modding can breathe new life into these classics, making them playable—and sometimes even better—on today’s hardware.
In this guide, we’ll explore the best methods to mod old games for modern PCs, including patches, fan-made fixes, and essential tools.

## **Why Mod Old Games?**
Before diving into the how-to, let’s look at why modding is often necessary:
1. **Compatibility Issues** – Many older games were designed for Windows XP or earlier and struggle with modern OS versions.
2. **Resolution Problems** – Classic games often max out at 800×600 or lower, looking stretched or pixelated on high-res monitors.
3. **Missing Features** – Some games lack widescreen support, controller compatibility, or proper frame rate adjustments.
4. **Bugs & Crashes** – Unpatched games may crash due to DRM, missing DLLs, or outdated APIs.
Modding can fix these issues while sometimes adding new content, improved textures, or quality-of-life upgrades.

## **Step 1: Find the Right Version of the Game**
Before modding, ensure you have the best possible base version:
– **GOG.com** – Specializes in DRM-free, pre-patched old games optimized for modern systems.
– **Steam/Origin/Epic** – Some classic games receive official patches, but others may need mods.
– **Physical Copies** – If you own the original disc, check if a No-CD patch is needed (legally, only if you own the game).

## **Step 2: Essential Modding Tools**
Several tools help modify old games for modern PCs:
### **1. Compatibility Mode & dgVoodoo2**
– **Windows Compatibility Mode** – Right-click the game’s .exe → Properties → Compatibility → Run as Windows XP (SP3).
– **dgVoodoo2** – Converts old DirectDraw/Direct3D games to modern DirectX, fixing rendering issues.
### **2. Widescreen & Resolution Patches**
– **Widescreen Fixer (PC Gaming Wiki)** – Forces custom resolutions.
– **Hex Editing** – Some games require manual .exe edits (guides available on PCGW).
### **3. Fan-Made Patches & Mods**
– **PC Gaming Wiki** – Lists essential fixes for hundreds of games.
– **ModDB & Nexus Mods** – Host fan patches, HD texture packs, and unofficial updates.
### **4. DxWnd & Borderless Gaming**
– **DxWnd** – Runs games in windowed mode, useful for fullscreen crashes.
– **Borderless Gaming** – Forces borderless fullscreen for smoother alt-tabbing.
### **5. Community Fixes**
Some games have dedicated fan patches:
– **Silent Hill 2: Enhanced Edition** – Overhaul for modern PCs.
– **Deus Ex: Revision** – Modernized gameplay and graphics.
– **GTA San Andreas: Definitive Edition Fixes** – Restores cut content and improves stability.

## **Step 3: Applying Mods & Fixes**
### **1. Install Unofficial Patches**
Many fan patches come as simple .exe installers. Examples:
– **NFS Underground 2: WideScreen Fix** – Enables 1080p+ support.
– **Fallout 1 & 2: Restoration Project** – Adds cut content and bug fixes.
### **2. Use Mod Managers**
For complex mods, tools like:
– **Vortex (Nexus Mods)** – Easy mod installation.
– **Mod Organizer 2** – Better for Bethesda/Obsidian classics.
### **3. Manual Modding (Advanced)**
Some mods require replacing game files:
– **Extract archives** (WinRAR/7-Zip).
– **Overwrite game files** (backup originals first!).

## **Step 4: Optimizing Performance**
Even with mods, some old games run too fast or too slow:
### **1. Frame Rate Fixes**
– **RivaTuner Statistics Server (RTSS)** – Caps FPS to prevent physics bugs.
– **DXVK (for Direct3D 9 games)** – Converts DX9 to Vulkan for smoother performance.
### **2. Input Fixes**
– **JoyToKey/Xpadder** – Maps controller inputs for games without native support.
– **AutoHotkey** – Custom key rebinds for broken keyboard controls.
### **3. High-DPI Scaling Fixes**
– **Right-click .exe → Properties → Compatibility → Disable Fullscreen Optimizations & Override High DPI Scaling.**

## **Step 5: Enhancing Graphics & Audio**
If you want more than just fixes:
### **1. HD Texture Packs**
– **Reshade** – Adds modern post-processing (SSAO, sharpening).
– **AI Upscaling (ESRGAN)** – Some modders use AI to upscale textures.
### **2. Sound & Music Restoration**
– **OpenAL Soft** – Fixes audio glitches in older games.
– **Modded Soundtracks** – Some mods restore high-quality audio.
