So your flash cart supports Byuu's mass storage idea which has a Der Langrisser patch for? If that's so that's awesome. Also you mentioned custom chip emulation which sounds awesome.
It is basically a 4GB data stream that can allow DMA directly into video RAM.
This can speed up processing: no need to waste CPU cycles decompressing graphics to fit into tiny ROMs. It can also enhance visuals: upload a new sprite animation every single Vblank. Games can store almost unlimited levels, so long as they upload levels to RAM first.
Maybe this thread should be split ("What is the largest sane SNES ROM size?" vs general sd2snes discussion) or subject changed to "sd2snes" or something.

This projects sounds really impressive, if indeed he can get those chips to run! Hope he or someone decides to produce them for sale though. Other wise, not so interesting.
Wow this looks like it will be so cool. Ultimate snes card if it supports all enhancement chips like superfx, dsp1, Cx4, etc. Also Not sure what all would be involved but satellaview support would be sweet. I'm sure that would probably be a whole new level of complexity and is probably more of a snes mod (like Ultra16). What ever the case keep up the good work would love to see another genius ikari project from ikari.
Satellaview support is already implemented
However some games, most notably the Zelda Inishie no Sekiban series, cannot be played (without patching) because they rely on data that was downloaded from Satellite to RAM during the actual broadcasts.
Oh, and S-RTC support is in. Time is supplied by the RTC integrated in the µC.
This looks (and sounds) incredibly awesome! Where's the order button?
