Hey Geppy? I just did another MSX to SMS hack of your game, changing those A0 and A1 ports to the 93 output direct. It has the audio converted to the SN76489. [/url]

I don't understand: do you mean that to have audio conversion is enough to replace ports A0h and A1h to 93h? I can't find relations to these ports on SN76489 guide you posted here...
Some explanations will be very appreciated

As you see, I changed these audio ports to CALL 0x0093 at the end.
