If the ROMs work fine in an emulator, they might just have a different iNES header or something, which would throw the CRC off. You can either try getting them from another source, or just apply the patch and see if it works anyway. The ROM should be 49,168 bytes; a larger filesize likely means someone added a junk footer that needs to be trimmed off, and a smaller filesize means it's a bad ROM. If any of that fails, you can just find the MAME ROMs and combine them into an iNES ROM yourself, though that's a bit more complicated... [EDIT] The message log in FCEUX should show the following: VS. Super Mario Bros. (VS).nes ROM CRC32: 0x98e3c75a ROM MD5: 0x39d8cfa788e20b6c7b62c9c07ee80f65 VS. Super Mario Bros.
