Linking assembled snes binaries

« on: February 21, 2010, 10:16:42 pm »

I have a bunch of assembled SNES files for an early alpha version of StarFox 2, however they are not properly linked and we don't have Argonaut's proprietary linker. Some have told me it might be possible to manually put together the files to make a working SNES ROM, but I have no idea where to start. The assembled files are separated into individual banks.

First try reverse engineering the object file format and convert it to another format for a linker that IS available.

Other way,disassemble it(bit more difficult on this CPU than usual).

Is each file less than 64K (or 32K?). If so, it's possible that they're just raw assembly and not object files. Thus, they'd be fairly easy to slap together into a rom using xkas.

Looking at the binary files, it seems there is still some text within them, possibly instructions for the linker. I don't know if some after the fact linker will be compatible with the Super FX assembly language. I don't have Windows, perhaps we can talk on IRC.
