Hello,
I'm building a flash cartridge and I noticed problems on older CGB revisions. My flash cartridge works fine on the newer revisions, but on older CPU revisions something must be different as the ROMs just crash. But I can't figure out what it is. Maybe somebody had done some investigations already. The most thorough info I have found is on BennVenns website https://bennvenn.myshopify.com/pages/gbc-cpu-revisions . He seemed to have had similar issues, but the post does not really tell what the difference is.
Is the CPU sampling differently? Is it glitching while it switches modes?
Would be nice if somebody had some information
