Hi again, Maybe some of you misunderstood me... I want the minimum configuration NOT for MSX standard but for EXECUTING EXISTING BIOS. Ok. How about this? I have a MSX2 machine and replace MSX2 BIOS ROM with MSX BIOS ROM. Then does the MSX2 machine work? How about in the reverse case (MSX2 ROM

Hi! For an MSX1 it will be enough with 8 KB RAM and 16 KB VRAM (if THE MSX RED BOOK is right about the MSX standard definition). MSX2 needs at least 64 KB of RAM and 64 KB of VRAM too. But no need of memory mapper, that's right (MSX2 Technical Handbook). Kind regards, Ed Robsy ___

Afaik MSX 1 BIOS only requires 16kB of RAM, and an engine to take care of several things. Oh, and a VDP, ofcourse. The BIOS will not work without it, even if it were only for the interrupt it generates. I think an MSX2 has basically the same requirements. Since there is an MSX2 model without a map

Tremolo is therefore certainly NOT a variation in volume, but a (mostly long) series of really short tones played directly after each other. However, in popular music, the meaning of the term has been altered by factories producing keyboards and musical software, because a simple variation in
