Thanks for testing! To make it easier, here's a couple of Game Genie codes:
PEXAPAGT = all enemies have 1 HP, so any hit will kill them (no interrogation, sadly
OZOIKTES = the communicator always takes you to the next level, regardless of enemies remaining
Now a couple of notes about different things.
I know the text is very slow, I actually have tried to fix that. There's a one-byte fix (Game Genie code LEKNEGTA) which makes the text go double speed, but when the text is more than four lines, it bugs out, because it only uses half the available lines as a result.
I'm not sure what would work best, or whether I should just rewrite the whole text routine to do it instantly. That might be worth doing in a separate 'bugfix' patch which can be done over this one, rather than part of the translation. For now, I think I'll just include the Game Genie code in the readme with a disclaimer that it won't look perfect (but will still greatly speed up your playing).
I've changed the names of three of the four team members so they'd fit in five characters (wasn't worth the extra hacking required to use six characters). Apparently it's based on an anime - it was published by Toei Animation, after all - but searching the internet turns up nothing at all. I'd love to see evidence that this exists. It was really cool to watch Time Stranger when I started translating that, but I can't find anything about this. Anyway, if Loto can become Erdrick, then I think Sakata can become Akira.
Reading the FAQ on GameFAQs is very interesting, because it suggests that, after a lot of playing, certain options in the game don't actually do anything, such as entering the room with a bomb, and in my testing, the only interrogation that seemed to make a difference was the Truth Serum: everything else gave the same result. I'll do some testing to see if the code is actually built to distinguish between these things, but it may be that the devs implemented these options but didn't actually get around to implementing full functionality.
