IMO don't bother with an M3 Real.
The reasoning is that there are many problems with it, even if M3 Sakura addresses some of these, it doesn't add any functions like these other carts have.
All the M3 Sakura is really IMO is a fancy GUI, and as we all know functions>looks. M3 Sakura adds some easier functionality in it for some light things, but not for much.
I've also been wondering about the SCDS1's built in emu for NES(?), that seems fun for me, wish more carts would have that built into their firmware, it would be nice to not have to choose your game twice when playing NES/SNES/Genesis/GB/GBC games.
