Doesn't it use ANY v9958-specific feature??? Not even the scrolling???
Well... that's cool to know.
I have found already 1 bug why it doesn't work on MSX2+: The memory
management.
It presumes the primary mapper to be in slot 3-0. Nowhere else. In the
turboR this is always true, because it always uses the internal RAM as
primary mapper because of the speed.
But on an MSX2+ with mapper this is untrue. Resulting in failing
slotswitching and datacorruption in the RAMdetect-routine (which is poorly
written, as well as the VDP init-routine).
I will continue my research and adapt it, maybe even make it Dos2-compatible
(which it now still isn't). And if it's true that it doesn't use ANY
v9958-specific feature then I could even run it on my MSX2!!! Which would be
cool, because it's twice as fast as my MSX2+.
