I've got FIDA and Gulliver Boy. Both work.
Slayers just won't cooperate with me. I cannot seem to find a rom that's (1.572,864 bytes), exactly. (as the readme tells me to). And I tried patching one that wasn't that size, with the expected result.
I found many sites offering me the game with the english patch already in place, but I'm always suspicious of those. (past experience tells me it's always best to get the latest patch and put it in yourself. Otherwise I could end up with a partial translations by other people, or early betas of your translation.)
Anyway I want to record the video on Thursday, because it needs to be posted on the first of the month (Friday). So if you know where I can find what I'm looking for please let me know. Otherwise I'll either have to choose a different third game
