Most ROM's seem to have the title at either 32704, 33216, or 65472. Is there a specific set of possible offsets or a good way to determine where the title is? I know that the difference between the 32/33's and the 65's is because of the length of the page in hirom vs lorom, but what's with the 512 difference between 32704 and 33216? | |||

Er, sorry. It would probably help if I specified that I meant specifically SNES SMC files. The documentation says that they will be at 32704 or 65472, but some roms seem to also have titles at 512 bytes away from these numbers. | |||

The documentation says that they will be at 32704 or 65472, but some roms seem to also have titles at 512 bytes away from these numbers. The extra 512 bytes is from a copier header being on the ROM. All offsets will be off by 512 bytes if the header is present. ---Evil Peer |

Ah, thanks a lot, that's exactly what I needed to know. |
