During some free time I ported the pacedev colecovision port to the MiST. I didn’t spend much time on it yet since I dunno if its worth. It seems that the colecovision didn’t got much attention in the past and thus not many games are available for it (and no scene demos).
Anyway here are the first impressions from a colecovision running on the MiST.
