Commander X16

It turns out the problem was with the "fake" SNES controllers I bought. Apparently their response time was too slow for the X16 and they looked to the system as if the SELECT key was always held down. So I trashed them and bought some used but tested genuine SNES controllers, and they work...

I am not sure where to post this bug report. There does not appear to be a specific forum topic. Anyway, I see what appears to be a bug in the X16MAZE game that comes on the included SD card. When I run the game with no SNES controllers attached, it works correctly using RETURN for start and Z for n...

The dollar amount was the correct amount for my CX16 order, but I have not received any tracking number. Does anyone know who DFW Resale is and what role they hav...
