I think it does ! I think gruetzkopf from #dsdev might have tested it and if it didn't work I'm sure he'd have let me know. (so basically, I'm not absolutely sure, but it should)
Cool! I'll give it a try later, let you know the outcome.
UPDATE EDIT: Seems both FPSMAKER and ACOTSYE work just fine in Sudokuhax! ACOTSYE runs fast and smooth, I haven't played it off flashcart so don't have any point of comparison.
Assuming your DSCRAFT and Portal projects will work in Sudokuhax too, it's finally looking like I have a use for the exploit beyond playing Quake!
Thank you for your great work on this!
