Go to the official SNES9x website. Download the Windows 64-bit version. Extract the ZIP file into your C:\RetroGames\Emulators\SNES9x folder.

On your C:\ drive (or a secondary gaming drive), create a folder called RetroGames . Inside, create subfolders: Emulators , ROMs\SNES , ROMs\NES , ROMs\Genesis , etc.

Press Alt + Enter to go fullscreen. Use Shift + F1 to save a state (save anywhere) and F1 to load it. Note: Save states are not a replacement for in-game battery saves. Part 5: Optimizing Windows for ROM Emulation Not all Windows PCs are equal. Here is how to ensure smooth performance. 1. Enable "Game Mode" Windows 10 and 11 have a built-in Game Mode that prioritizes CPU/GPU resources for gaming. Go to Settings > Gaming > Game Mode > On . 2. Disable Fullscreen Optimizations (For Older Emulators) If you experience stuttering or input lag in old emulators (like ZSNES or ePSXe), right-click the emulator’s .exe file > Properties > Compatibility > Disable fullscreen optimizations . 3. Use a Wired Controller Bluetooth introduces latency. While fine for RPGs, if you are playing fighting games (Street Fighter II) or platformers (Celeste classic), a USB wired controller is superior. 4. Shader Caches for Disc Games When running PS2 or GameCube games (ISO files), Windows may stutter the first time you play. This is shader compilation stutter. Play the game for 10-15 minutes to let the cache build, then restart. It will be smooth afterward. Part 6: Where to Find High-Quality ROMs (Safely) Warning: Many ROM sites are riddled with pop-up ads, malware, and fake download buttons. Never download a .exe file as a ROM. ROMs should be .nes , .smc , .sfc , .gba , .iso , .bin , or .chd .

If you own a physical SNES cartridge, dump it using a Retrode 2. If not, download a free, legal homebrew ROM like Dizzy's Excellent Adventures (check archive.org for public domain titles).

Many newcomers assume that "PC ROMs" refer to old PC games. In reality, the term "ROM" (Read-Only Memory) typically refers to digital copies of cartridge-based console games (NES, SNES, Sega Genesis, Game Boy, etc.). When you search for "PC ROMs for Windows," you are generally looking for a way to emulate console games on your Windows computer.

If you build your ROM library ethically—by backing up your own games or supporting homebrew developers—Windows becomes the most powerful retro gaming console ever created. It unites the NES, SNES, Sega, PlayStation, and Nintendo 64 into a single, 4K-ready machine.
