PSP Homebrew Developer bosshunte has release btcnfpatch.prx for CFWenablers for Version 5.03 on PSP 2000 and PSP 3000 models. That is btcnfpatch.prx ? this is the patch that you need to install in order to play ISOS, PSX games and specially to improve stability to IrShell
Note 1: This patch is only working on CFWe 3.50 version and below. With CFWe 3.60 you can still play ISOS but the PSX games won’t work.. (The game could not be started. (800200E5))
Note 2: It is only for firmwares 5.03 on PSP 2000 or 3000. (Tested on both. Phat not supported as you can install CFW on it)
Note 3: This utility touches a file installed by CFWe in flash0 so USE IT AT YOUR OWN RISK.
Note 4: If something goes wrong while the prx is patching the file (ex: PSP turns off because of low battery) and CFWe is no longer loading, you can always reinstall the CFWe and run the patch again.
Make sure you have:
- IrShell 5.0 installed.
- A fresh install of CFWe (if you have done my other tutorial, you’ll have to reinstall CFWe to run this utility).
- Plugins in game.txt are disabled (If not you’ll probably get a black screen when running the prx. Just do a hard reset if this happens. Then enable ChickHen, run CFWe and try the patch again after disabling the game.txt plugins. Kinda looks like a pain but.. You only need to run this once!).
- Replaced the provided IRSHELL folder in your memory stick.
Instructions: (same as the old IrShell patches)
- Run IrShell
- Open Directory View and go to ms0:/IRSHELL/PATCH/5.03/
- Run btcnfpatch.prx
- Press X to start patching
- Wait a few seconds and you’re done (you should see the following screenshot on your PSP if the update is successful).
- You can now re-enable your plugins in game.txt.
