Ah seems my memory was bad there. I must have had it confused with another emulator, however that sounds while it wouldn't be trivial to rewrite those sections it shouldn't be very difficult to do so either, just very very tedious. I think other than that there could only be a licensing issue, and I seem to recall that bsnes had a fairly liberal license that shouldn't run into any problems. Though obviously you'll know better than me byuu :) In that case it's all about time and who has it that'll determine when/if it'll happen
