Shin Megami Tensei 2 Playstation 1 Translation

GengarsGhostlyGiggles · Sep 26, 2025

Does anyone want to start a team or point me in some directions. I'm getting a degree in comp sci, but I'm shit at reverse engineering stuff.
I'm trying to start a translation of Shin Megami Tensei 2 psx (and Medabots 9 3ds) in the future.

Right now I've got shin megami tensei 2 partial dumps, and can insert various menu english ui/ux and compile it, but I'm still confused as hell around story shift JIS compression and textures in playstation one games.
Also whats up with full width english vs narrow english text.

I'm just have a hard time in general with the MIPS address decompilation of routines, and my professors at a top 30 schools are F*CKING USELESS.

Full width "English" letters are just Shift-JIS characters for English (romanji).

You'll need to either compensate for that (width hack) or implement your hacked text system into the game. The former is easier, so most opt for it.

I'd also like to say that most university professors are absolutely fucking useless for anything other than what they're teaching. Most barely teach anything good, and when it is, it's a basic Windows batch script that could be copied from the internet, or even an AI chat bot.

Dont know if you're still trying, but I found out that the story texts are probably inside PACKA.BIN file. Looks like they use the same encoding/weird processing method the SNES version uses (I literally just searched for a byte sequence from the SNES version on the PACKA.BIN and found it)

Since the SMT2 SNES translation apparently changes this, we can look at how the code was changed and try to do the same on the PS1 version, but I'm also kinda bad at reverse engineering...
