The header should be correct, though the checksum value isn't (it isn't required anyway). It works on donor carts and the new PCB's I use (2MB / 4MB vanilla boards as well as 2 MB flash boards). If you have any issues, feel free to PM me if you need any help
Thanks. Just needed to make sure I do not need to populate an SRAM. In that case, I can also ignore the hgih ROM and my logic.
Cheers
Nope, no SRAM is needed
I was actually debating on that to save high scores, but at the time I didn't have enough PCB's to make that happen, and the design for the flash boards with SRAM weren't ready yet (are now, and won't be able to use donors for new releases )
Yup, same reason I designed these board was to make it difficult (but not impossible) to use a donor. AP-protection.
I created a specially mapped SRAM which covers the common 32K-loaction, but expands on it outside of the range any official cart used. I also focusse on support for official games 2MBytes or less. If the ROM is less than 1MByte, then I only need to pupulate one IC and an SMT jumper.
