I doubt this is mGBA's fault because this also happens in a 2004 version of VisualBoyAdvance and the current VBA-M release, even with vba-over.ini present and modified to account for the three Donkey Kong Country GBA games. I'm just trying to find answers why certain *.sps files don't take effect. I've had some successes and some failures with this import feature. I am having issues importing a GameShark Save for Donkey Kong Country 3 from GameFAQs. I go to the file select screen in-game after importing and I see no 101% saves. All slots are blank. Is there something wrong with the decoding algorithm in all three GBA emulators or are saves a pain in the butt (which has been an issue from the start of GBA emulation)?
