I dropped a message at the colecovision programming section.
If someone can help me, we might have Coco with sound. It would be great.
Tomorrow is the last day for high score Boulder Dash / Popeye.
I don't care too much with Popeye but I still improve with Boulder Dash.
I believe there are 2/3 more caves to complete before going back to cave 1 with level 2 but more difficult.
