Raw Game Fails to Load, but ELF Works

[ammrat13]

Running mGBA version 0.9.1 on Arch Linux from the repositories (package mgba-qt). CPU is AMD Ryzen 5 2600X. GPU is Nvidia GeForce GTX 1650 Super.

I'm trying to test my homebrew game on mGBA. Source, object file, ELF file, and GBA file are in test_game.zip. Loading the ELF file into mGBA works fine, but loading the GBA file gives

The game has crashed with the following error:
Jumped to invalid address: 00000000

I haven't looked at the file yet but my first guess is that it's misdetecting whether or not it's multiboot. Will look in depth in a bit.

[ammrat13]

Probably. It's being loaded at 0x0200_0000 instead of 0x0800_0000.

Resolved by making the ROM file 32MiB. Probably works because of the check here.

Yes, that check will resolve this, but I'm concerned that it's misdetecting regardless.
