One chip MSX improvement project
no! the license type isn't compatible to GPL for now, sorry! 
some suggestion???
> F1 Spilit 3D Special
The horizontal scroll was synchronized with the H-SYNC signal.
It might be a cause possibly.
I examine it 
That's MSX2+ compatibility, isn't it?
It becomes MSX2+ compatible as hardware.
However, BIOS on EPCS4 is MSX2 compatible.
For instance, KANJI-BASIC cannot be used.
If MSX2+ BIOS is prepared on the SD/MMC card, it becomes MSX2+ compatible
The scrolling takes too much time?
I tried "F1 Spirit 3D special".
"F1 Spirit 3D special" takes timing by doing VDP-S#2 in polling.
If it is 10MHz mode, the scroll display is improved.
I think that the timing of the horizontal synchronizing signal is different
from the real thing.
Sprite falls into disorder, too.
The cause has not been clarified yet
