In our previous guide on modding Persona 3 and 4 (PS2), it was mentioned you’d need to use paid software UltraISO to repack your modified files into a new, bootable ISO. Thanks to new patches by TGE, repacking ISOs– and even CVMs– is finally a thing of the past.
While this method should work on any device or emulator that runs PS2 games (as long as there’s hostFS support and a way to boot from an ELF), this guide will only focus on PCSX2.
The only prerequisites are:
- A North American ISO of P3FES, P4 or SMT3: Nocturne
- TGE’s Mod Compendium
- PCSX2 1.5.0 (Older versions probably won’t work!)
- A text editor (i.e. Notepad++)
This method does not require you to modify your ISO at all! Instead, we’ll be using a code patch that makes the game load files over the local network (your computer’s filesystem) rather than the archives in the ISO. This method is 100% free, and results are pretty much instant every time you change a file, even while the game is running. So it has several advantages over the old method, which could take around 10 minutes each time, even with optimal hardware.
