There's a patch i found which will re-insert music and the portraits from "Rushing Beat Shura" into "The Peacekeepers" for the SNES.
Problem is, whenever i patch the rom and load it, i get a failed checksum and bad rom message (I'm using ZSNES BTW).
I'll link you guys to the patch, and hopefully i can get some help on what i'm doing wrong.
EDIT: Here's a link to the actual website the patch is hosted on, as opposed to a link to the patch. It's the second article down: http://web.archive.org/web/20030701133136/http://underworld.fortunecity.com/virtua/513/noframe6.htm
