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!
