MSX2-MAPPY does not work on C-BIOS, because C-BIOS determine the screen mode by examining SCRMOD(0FCAFH) .
I only have directly modify the VDP register, I don't change the data of 0FCAFH.

After you start, please write 4 to 0FCAFH.

Thank Tiny Yarou.

I would be happy if you can convert "Dunk Shot Super Players" (Hal) to MSX2.
This game would be much better if the sprites were not blinking as much.

PS: I fixed the ROM and reupdated my link. :D

Really great work, thanks Tiny Yarou! I love those MSX2 upgrade to classic games. Are you planning to do another game enhancement like this one?

MAPPY, there was some reason that is easy to enhanced for MSX2.

1) Program and data are in 16KB or less
I was able to put program and large data for MSX2 in a vacant area.

2) Sprites are used only 32 or less
MSX2 can define only 64 sprites(16x16), as many as MSX1.
Because MAPPY is using sprites only 32 or less, I was able to make two-ply sprites easily for MSX2.

3) Use SCREEN1
Since MAPPY works on SCREEN1, each BG-character is a single color. So I was able to freely change the palette.
For example, Konami is making full use of the specs of SCREEN2, and using many colors in each character, there is a large influence just to change only one palette.

Other game might not be easy as MAPPY...

Did you try? Tiny Yarou said that the SCC sound is not really good.

Yes, maybe not the best composition ever made, but the SCC chip sounds.

Try yourself and take your own opinion Wink

I have played several times this great MSX2 Mappy and enjoyed a lot! It looks great! Real arcade experience! Thank you!! Big smile I have always hoped that MSX-1 Mappy could have used more sprites to make multicolour sprites. At least to give Mappy himself a pair of eyes and/or grey body colour. It would be nice if somebody could hack MSX-1 original to make such changes. MSX-1 Mappy has a sprite flicker routine already, though I don´t know if it will still work properly after more sprites have been added. At least I would like to know if such hack is possible. Smile Even better if such hack is possible to add to same .rom and it would work on MSX-1 too. Smile Would it be any easier solution to modify MSX2 Mappy to use MSX-1 colour palette and add more sprites? That would not run on MSX-1 but it would look cool! Cool
