So I tried various tests and various things, and I have been able to make a 64k cartridge instead of a 32k one. But there is still more work to be done. I want a 1 mb cartridge. I am still trying to get this working. I don't know if/how I will get what I wanted. I am having trouble understanding it, too. Apparently a 64k cartridge is 4 16k banks. Yet I am able to fit the whole game so far without using any of the other ROM files I used to merge or whatever I did. But anyway, I have a 64k cartridge ROM. I don't know how or what I did, though, which will make it tough going forward. I worked on a few changes to Mouse in the House for the Odyssey 2.
