About This PCSX2 PNACH & Widescreen Generator

This free browser-based PNACH file & widescreen patch generator helps PlayStation 2 emulation fans quickly convert cheat codes into the correct PCSX2 format, optionally merge official community widescreen fixes, and download a ready to use .pnach file. Everything runs client-side for privacy. Just paste codes from Raw, CodeBreaker, Action Replay, or GameShark style lists and the smart parser normalizes them into patch=1,EE,<address>,extended,<value> lines. You can also add manual patch rows, choose a header style, and auto fetch a 16:9 patch from the public PCSX2 widescreen repository when a supported CRC is entered. Designed to be lighter, faster, and more helpful than older generators that force page reloads, this tool provides instant validation, dark mode, and mobile friendly layout. Use it on Windows, Linux, Steam Deck, or a phone — no account, no tracking scripts, just practical functionality.

How to Use

  1. Open your PCSX2 log after launching a game or search for its CRC value (eight hex characters). Paste it in the CRC field.
  2. Paste any cheat code list into the Cheat Codes box. Mixed formats are okay; invalid lines are skipped but reported.
  3. Add any extra patches manually by entering address, value, selecting type, then pressing Add.
  4. Leave Widescreen Patch on Auto to attempt fetching a native widescreen patch from GitHub for that CRC. If none exists you will see a helpful note.
  5. Press Generate to build the PNACH preview. Copy or Download when satisfied. Save the file as CRC.pnach inside your PCSX2 cheats folder.
  6. Enable cheats in PCSX2 settings and reload the game to apply new changes.

Tips & Troubleshooting

Double check each address and value pair; a single mistake can crash a title or silently fail. If a widescreen patch fails to fetch, the remote file may not list your CRC — try a fork or contribute upstream. Keep codes minimal: stacking conflicting 60 FPS, no interlacing, or speed unlock patches can destabilize timing. Use only one render fix at once. If a patch uses a type prefix like patch=1,EE, with a data type other than extended, choose the proper data size in the manual section. You can toggle dark mode for late sessions, and turn off auto formatting if you prefer a raw block. Share feedback or contribute improvements; this lightweight file is easy to embed in WordPress (Kadence), static site builders, or local documentation.
