This Version use Music Module x 2 for Enhanced the Audio Experience but PSG is still active also.

The next version will be Music Module x 2 but with original SN76489.

Enjoy!

P.S: I forgot to mention this version is GR8NET Compatible at last. ;(

@Sander: Well, after try RicBit conversion from Colecovision I have noticed the nice SFX in its original Colecovision SN76489 Version but I was craving for better sounds so I decided to apply my recently acquired knowledge about Y8950-ADPCM and just add those Arcade Samples and the final result was great. Also I have added Compatible Versions for FRANKY/PLAYSONIQ and Musical Memory Mapper Users.

Alexito use Y8950-ADPCM x2 (MSX-Audio/Music module) to add samples in game.
