j ais trouvé un source hélas en assembler qui est modplay.asm issue d un source de mvsplayer. Il donne un apercut de command fonctionne la parti song neogeo.
; -------------------------------------------------
;
; NMI - used for inter-processor comms
;
; -------------------------------------------------
NMI:
org 66h
push af
; read in command from 68000
in a, 0
; if the value is zero then end
or a
jr z, NMI_End
; if the msb is set then the value represents and FM command
or a
jp m, NMI_ProcessFM
; else it is an ADPCM command
jr NMI_ProcessADPCM
NMI_End:
out (0ch), a ; acknowledge?
pop af
retn
voici les commandes nmi qui lie le 68000 au z80. Mais quelques inconnus reste comme ce headers
Z80moddriver.h
const unsigned char Z80ModDriver[] = {
0xf3,0xc3,0x25,0x01,0x00,0xff,0xff,0xff,0x7a,0xd3,0x04,0x7b,

0xf8,0xba,0x20,0x07,0xaf,0x32,0x0f,0xf8,0xcd,0x06,0x03,0x11, ..................etc
qui contient je ne sais quoi
