Can I get some help on getting Secret of Mana on a 8MB INL Cart from Kazzo? I've tried padding the rom to 4MB and 8MB and it still doesn't work. I clean/wipe to cart before I put any rom on there, but it doesn't seem to be working.
On the Super NES, you shouldn't pad it up; you should instead duplicate it up. The exact method of doing that depends on the size of the ROM file in bytes, particularly whether it's a power of 2 bytes in size or a sum of two powers of 2 (usually 10, 12, 20, or 24 Mbit), and whether it has a 512-byte header for obsolete floppy disk-based copiers.
Can you get other 2Mbyte HiROM games working on that board?
If so, just try it again with a fresh No-Intro version of the game (doesn't have any header to remove), and see if that works.
Do yourself a favor and get Danins software. It automatically pads roms ect and makes the whole process much easier. You should be able to get it working on a 4mb board without issue.
