so I was going through my trade bait for PRGE and I had a complete copy of Crystal Mines from Color Dreams. its on ok shape, manual was laminated as it was a previous rental. I popped it in to my top loader and it wont work. it boots to a scrambled screen.
well crap.
but I remembered I had another copy I bought years ago as Athena and found it had crystal mines in it instead, so I thought I might as well swap PCBs because the Athena one worked. so I cracked them both open, tried cleaning the complete one to no avail so I opened Athena up. its been missing 2 screws since I bought it and the screw holes were widened a little near the top for some reason. I open it up and I notice theres a windowed EPROM with a red sticker over the window.
the complete copy has a MASK rom. the Athena cart wasn't as nicely put together as the complete one I had.
is this normal or did I find a thing?
also these are probably not going to be trade bait any more
