MMM cartridge + MSX -> ColecoVision's games

It's interesting but it would have been better to say it in the right thread.

Here we are talking about conversions for MSX + SN76489. I chose to use the SN76489 because whatever the ingenuity deployed, the sound conversion to PSG or SCC is less good and even sometimes bad for several games. Even openMSX doesn't emulate this chip well enough for my taste. For me sound is important in games. The SN76489 is a solution simple and inexpensive and it also allows to improve the sound by using the MSX's PSG at same time for people who prefer make enhanced conversions (like Gyruss from Repro Factory).

As for me, I prefer to make conversions first the most faithful to the originals. I only modified a few games to correct bugs or a small detail that bothered me.

Rest assured I also like the enhanced versions (Jungle Hunt, Montezuma's Revenge, Tutankham, etc are nice) and PSG versions but it's just that I don't have time to do it. I therefore privileged the pleasure of seeing the Coleco games function as on the real ColecoVision console.
