Problem is that would have been a cool when PCs were not fast enough to emulate the amiga. Nowadays it would not add anything you can't already have with winuae. Same would apply to a playstation one emulator on a card, you can already do that in software, why do you need a PCI card also?

SDRAM or DDR?


Wouldn't DDR provide more bandwidth just in case someone wants to improve the AGA chipset or implement some kind of RTG graphics to provide 15/16/24 bit modes?

Any pipelined dram may actually waste a lot of (dram) clock cycles as the Amiga doesn't really expect such functionality.

Yes and no, isn't the 31 khz modes achieved using the extra bandwidth the installed RAM provides? Back in the day the Picasso IV had to use EDO RAM (45ns) and a 64 bit chipset to have enough bandwidth to display 1600x1280x16; that is the reason I suppose that with faster RAM it would be feasible to implement AGA+ or Picasso96 compatible video modes.

In order to insure that the SDRAM works, the answer is complex and may be out of scope for a simple post ... If you really want to know more about this, I can write up more after I finish assembling my MiniMIG1.1

Since nobody answered to this post either people find this knowledge fascinating but completely out of our grasp (like me) or already know about it (I am hoping there are a few in this category, otherwise we will be stuck with 2mb or worse, with a hardware design that overtime becames imposible to implement because those chips can no longer be obtained).
