While great hacks no doubt, as someone who grew up with the GBA version and has nostalgia for it, the screen crunch makes me unable to go back to, same thing with Mega Man & Bass and Yoshi's Island tbh.
Instead, what I'd really like is a hack of the SNES version (Super Mario All-Stars+World) that brings all the voice lines and level design changes from the GBA to the SNES, and perhaps ports Mario Bros. Arcade from the GBA as well, that version would be perfect if it's not for the screen crunch and had proper local multiplayer.
