Now this is nice! This would have been right up there with my favourites (e.g. Tom Mix) had it been released “in the day.” Makes my heart warm.
A note that I first tried this on a real CoCo 1 and it works perfectly apart from a constant buzzing during gameplay. Sounds like the speaker is being pulsed. No such issue running on an emulator.
This “buzzing” on hardware has been confirmed by others. Any chance this could be looked into - probably a simple fix I imagine (or would hope).
