Failed to dump GBA bootleg

[Sanqui]

Hello, I have a GBA bootleg cartridge that I am interested in dumping for preservation purposes. When attempting to use GodMode9i, it successfully reads the game title from the header (as GBA GAMECART (PO Crystal )) but an attempt to dump the ROM (or All) returns Failed to dump the ROM. Would it be possible to diagnose why this failure happens and implement support for cartridges like these?

Bootleg cartridges must be dumped with a different tool called GBABF due to how they work. Browse to the following repo, and download the binary: https://gitlab.com/Fexean/gbabf Use the dump data option and select the size to be 16MB or 32MB.
