I am not holding back anything but as I am new to this platform I have to find some solutions first, like how to play music, which format etc. When I have a clue about that, then I can continiue on the rest. It is a kind of action puzzle game
There will be a new designed one soonish
If he could sell the revised board with a mounted flash chip, programmable by tapping into the hucard pins (like I imagine it is on the Arkhan's abcard), it would be great. And a built in One Time Programmable chip for homebrew runs.That could be done with just a few board modifications. If he added a few solder pad jumpers to the control lines the HuCard flash combo could be shipped in write mode and then after you program it just move the jumpers over to read mode.
With today's technology, I wonder why not consider just making them exactly like the original HuCARDs?
