Yeah, more than likely its a header issue, pulled this from the readme for the Rockman & Forte Translation.
If using ZSNES, make sure that the patch has the same name as your ROM.
In other words, if your ROM is called "rockman.swc" make sure the patch
is "rockman.ips" okay? If you're using a Mac, a Mac IPS patcher is
available. Check the AGTP Links page. If you're using a copier, you
probably already know how to patch the ROM
Be sure to apply the
patch to a clean copy of the ROM, and make sure your ROM DOES HAVE
a header. If you right-click the ROM and select Properties, it
should read "4.00 MB 4,194,816 bytes)". SNESTool can add any headers
for you easily, and you can find it athttp://rpgd.emulationworld.com
In the utilities section, click on the IPS Tools link.
Please note that the questions it prompts you for apply to copier-users
only; if you are playing the game in an emulator, your answers do not
matter. All that matters is that the header is -there-. SNESTool will
tell you "Header add to file(s) done." and you'll be all set.
