Yeah, its working. Have been playing Super Mario Word last night. Did a few tests with different roms. Mainly Lorom, type 0 without save game ram. Was able to run games up to 16bmit. Couldn’t find any 32mbit type 0 games to test the complete ram area. Anyways its working finally. What de did? Resolder the cart connector and cleaned the contacts 🙂
And some pictures of the OR gate hack:
Now its time to work on the software side. Stay tuned.
