The question is: How can I optimize the ASM code? It's possible?

Your code not think we can more optimized.
But you can put faster instruction for example:
"and.w #0xffe0, %%d1 \n" ==> andi.w #0xffe0, %%d1 \n
"add.w #0x200, %%d0 \n" ==>"addi.w #0x200, %%d0 \n"

I find asm inline not very nice (or so it's asm gnu I don't like :P).


it is you who made the graphics? (Yes I find it strange to the 8-bit game on neo geo ).
I'm curious to see the final result

Thanks Kannagi,
the graphics are ripped from the Phoenix's ROM.
The real objective of this little project is a working Z80 emulator for NeoGeo hardware with some '80 Arcade Classics to play
