I will bet $5 that if Bust-A-Move gets ported, it will be the SNES edition, not the Neo·Geo version.
This really doesn't matter though, because when I was little Bust-A-Move was in our pizza place, and we rented the SNES version the same day from the video store, and even at the age, the only thing I griped about was the sound (not as punchy for some reason, bad samples perhaps).
The ABSOLUTE worst version of Bust-A-Move I have played is the one on the VGpocket Tablet handheld. Major slowdown, shitty sampled sound effects (both due to the hardware and a sound designer who was obviously so rushed he just used the line-in on his PC to record them) and a HORRIBLE General MIDI library (the other games are not so bad, it's just the Microsoft GS synth, but this is HORRIBLE).
