ah, that might actually be a complete dump, the JP versions of Gold and Silver (which the bootleg translations are based on) are 1mb each so that's big enough to contain both of them.. drop me an email at cactusgunman@gmail.com and I can take a look at it if you like.
If the ROM is complete the issue will most likely be that emulators can't handle the multicart mapper (and potentially copy protection, the single cart releases of those translations had something like that going on)
