10. EmuDeck

The folks handling the EmuDeck project already have a guide specifically for Persona 3 FES on their GitHub wiki. I would recommend reading through it for the steps specific to EmuDeck.  At this time they do recommend an outdated version of the party control mod. The updated one is here. Any steps regarding CEP in their guide can be replaced with the contents of this guide.

Your mod folder will be copied to Emulation/roms/ps2. You can rename the mod folder to anything you want, like P3FES.

The section labeled “On the SteamDeck” can be skipped as it covers extracting your ELF which we did earlier.

Instances of SLUS_216.21.ELF can be replaced by whatever you named your ELF file, like Persona 3 FES.ELF

Make sure to copy your ISO to Emulation/roms as well.

Your cheats folders are copied into /home/deck/.config/PCSX2/

Your textures should be copied into one of the following paths.

Internal installs: /home/deck/Emulation/storage/pcsx2/

SD Card Installs: /run/media/mmcblk0p1/Emulation/storage/pcsx2/ (Note: mmcblk0p1 may vary depending on the device and partitioning, please double check your emudeck settings)

Follow these instructions to enable texture replacement.

Make sure specifically for FES you disable usage of widescreen patches (they’re outdated), and use the one provided in this guide. Individual game settings can be changed as detailed here.

Lastly, make sure you set your render resolution to 2x or higher in the emulator.
