Ability to load debug info from an external file?

[EvilJagaGenius]

I work on a fork of the Goomba Color GB/C emulator for GBA and use mGBA to test my builds. However I don't have a good way to debug it. When I compile, I come out with a .gba and .elf file as per normal, and Goomba Color works by concatenating ROMs to the end of the .gba file. When I try to do the same thing and build a test ROM with the .elf file, the emulator doesn't detect any ROMs.

Would it be possible to add a debugger command to load debug info from an external .elf file, like GDB does with its add-symbol-file and symbol-file commands? Then I could build a working test ROM and have all my function/variable names in the debugger too.

Thanks!

It should autoload .elf symbols if there is an .elf in the same directory with the same filename. However, I can add a manual loading command.
