Hi,
I was discussing with someone who is developping a asm game on a MSX2+. He told me that the MSX2+ BIOS calls (CHGMOD / CHGMDP) had not been modified to include the new graphic modes of the VDP 9958.
So for example, to go into SCREEN 10, he goes into SCREEN8 and then changes some VDP registers to switch into SCREEN 10.
Is that really the case ?

Technically it
These days with gfx9000 and FPGA systems around (and existing software base), not very relevant anymore...
