Maybe you have read the more recent news on our homepage nature.atari.org, where we talk about mirroring the ST-RAM into a 16MB block of the graphics RAM for compatibility? This way old games and demos should work without modification, since the SuperVidel doesn't interfere with the normal writes to the ST-RAM, it just copies them.

But this also doesn't give any speed boost, since the motherboard bus is still responsible for terminating the write cycles, and thus controls the length (in clock cycles) of a write. New games and demos must use the other portion (48MB) of the graphics RAM, to benefit from the speed increase, since the SuperVidel then will control the length of write cycles itself.
