Well, I ran into a strange problem. Maybe someone can assist me.
I've taken the CHR and PRG chips from "Adventure of captain comic" and used my trusty EPROM reader/writer to dump them. I've than used tnines to merge the 2 dumps, create a header and play the game perfectly fine on my PC in an emulator. I read the EPROM chips in 27C512 mode.
I've then taken another color dreams game, burned it on CHR/PRG (and confirmed it) to 27C512 chips (120ns) and soldered them onto the cart. For some reason, the cart doesn't want to boot!
I disabled the security chip in my NES and have confirmed with voltmeter all traces. The color dreams game I burned is identical to captain comic (in size, mapper setting and orientation). Anything I missed???
