But they all have to be 100% compatible with the MSX standard.
The later standards should only be expanding the original MSX standard.

Not true. The MSX standard is defined in the MSX Technical Databook. The MSX 
Red book is just an analysis of the MSX1 standard by Kuma software. Not by

MSX2 is 100% compatible with MSX. AFAIK so is MSX2+, unless it lacks cassette
