Hi All!
This is my second repro. I did Mega Man last week and everything went great! I just finished Metroid last night (donor from 720), and am having some issues with it.
First off, on the title screen, there is a floating square in the middle and blinks and moves a little, similar to the selector from the next screen (after you hit Start). After you hit Start, then hit Start again to start the game, it shows this glitchy blue screen and then after about 5 seconds, the game restarts back to the title screen. I am using a ST M27C1001, which I did view the data sheet for and matched it to the pinout of the MMC1 board (720 is actually a MMC1B2, but apparently they are nearly identical). When I received the donor cart, some of the contacts on the cart were a little corroded, but I think I cleaned them up enough. I also have tested all of the traces with my multimeter and none of them seem to be broken.
Thanks for all of your help! I'm getting a kick out of all this soldering and 'intro to electronics'!!!!
