About the sd2snes pro

The new sd2snes pro can support msu1 games with all the enhancement chips, besides the additional channels to reproduce audio (like the killer instinct, wich sounds with music and one voice from the msu1).

But i was wondering if it could be improved supporting more msu1 channels for more custom voices or sound effects, so, the question is, What is the state of the actual cartridge to add more functions?, Is there enough power to implement things like that?, or maybe we must expect a third revision.

Greetings.

Just a suggestion, any technical sd2snes questions would be best answered by posting over at Krikkz's forum:

You will probably get an answer much sooner than here. Much luck.
