Developing newer software programs.

Unless if someone process the pre-calculation on the Main RAM and later only pass the 6KB values to the VDP, even with the slow down of the outputting task the average speed on the system could be increased.

It should not work very well, since a older VDP would slow down the main CPU ... We need a fast video processor that could be binary compatible with the old video ports . With newer processors using a legacy mode (compatible with old hardware and software) it would be possible to make a boasted MSX2/2+ machine ...

One question. Some fast Z80 compatible CPU from Zilog (logically), Kawasaki LSI, etc exist so it seems we have options to chose. As I doubt a MSX VDP compatible with MSX exists , I guess it could be replace with a FPGA and solve the speed difference. Right?

Probably this should be easier, but in this case why the need of a differently CPU? It would be nice if someone managed to finish a V9978 ... 20x faster should be enough to couple to the basic speed of the turbo processors!

Anyway, maybe LSI logic could be cheaper than FPGA logic ... And there is the need to integrated the Sound Processor too. I believe that with enough CASH it is possible to order LSI parts from several places. The main problem is that not everybody has the Million dollars that it would require!

Just one LSI could integrated most if not all the integrated logic that a home computer or game console would need!

nice idea yukio, in fact fpga are very suitable for that, i have been toying with the wb_z80 from opencores recently , running it easyly @24MHz with one instruction per cycle i have not tried to push it further, it is supposed to reach 300MHz.... whaoo that is fast !
