Good luck with your thesis, Blackiris!
Aqualung: That's the plan! Once I get the okay from enough of the testers, and the patch is seen as fit for release, I will make the manual available and start putting together the readme.
I don't want to release the manual too early, and have everyone still have to wait a month or something. Even the box was released way too early, in my opinion.
I don't know about stats, but if you can run the Japanese rom in bsnes, you can run the English one. Many testers have said that they couldn't get bsnes to run it well, but after I told them my configurations and emulator version, it solved the problem for all of them.
The translation doesn't require a modified version of Higan. As far as I know, it will run on the official Higan, and bsnes (that supports xml). So far, it's only been tested on bsnes, but I e-mailed DougRPG, asking him to make a bml file so it can be played on Higan, too.
