Hmmm. I seem to be having some problems getting the patch to work on the Metroid I've got (which is, incidentally, the [JU] version). When I apply it to the ROM, I get the 'title' of the ROM in ZSNES listed as <-<-<-<-<-<- (lots of left-pointing arrows), and the chksum is 'FAIL'. Thought the problem might have been a missing header, but SNES-Tool tries to remove the header instead of adding it when I tell it 'add header', so obviously there's a header there. Tried it with both ZSNES 1.43 March 29 WIP (yes; I know what the readme said about version 1.4x) and 1.36. Both of them show the same problem. Checked the game. So what else am I missing? Probably something really simple, but I can't think of it at this moment.
