OK. Not hard to do, just annoying. Since the game might use more than one table if what I see in the PPU viewer is correct. Text tiles in the opening intro, title screen, stage select, etc, appear to correspond to different bytes.
That seems a little strange... but I guess it's not unheard of. Given what little text this game has, I didn't think it would be such a job
But I'm still going to need a table making program. Hex editing by hand without a table file (since I don't know how to actually create one), isn't exactly newbie friendly.
I don't really have any to recommend. Tables files aren't exactly hard to make my hand, though. They're just plain text. Open up any table file in a text editor like notepad and you should be able to figure it out instantly.
