Great news! Thanks for working on this!
Before I step on anyone else's project, I guess I should also say I've started the groundwork for Shin Sedai Shuumei.
This was a quick test I did, to see if I could find text stored in RAM and read the text format (it's S-JIS).
Since then, I've managed to trace a table of contents of the main data file in the disc, and split it into individual files.
I'm currently working on joining it back into a working condition after modifying the text files (I already wrote a joining script for it, but I haven't tested modified files of different size yet)
After that, I'll work on a font replacement, and a custom VFW code.
I was in talks with Tom about the actual translation, but I haven't heard back from him since this whole situation you're all aware of (and I don't plan to bring up yet again)
Either way, I still plan to finish "the hacking side" of the project.
... So if anyone else has been silently working on the game and has more progress than me, now it would be a good time to know about it!
I'll pick up another PS1 Goemon game instead.
What about Ooedo Daikaiten?
