It was misleading as to how the M3 group named the bundle at the time. I believe the name at the time was "M3 DS Real perfect bundle" or something similar.
I don't have the SD version or the CF version of the M3 perfect (GBA flashcart, not a GEP). I have the microSD version of the M3 perfect. They should all work the same as a GEP if you use GBA ExpLoader, you might erase your game data in SRAM using GBA ExpLoader. I have used it a few times as a GEP without any ill effects to it operating as a standalone GBA flashcart.
The M3 perfect is not a GEP, but can work like one.

The reason I listed it as "all versions" is because on the PCB, it suggest that there was more than 1 version of the GEP.
