Hacking 3in1 - GBA functionality equal to M3DS Real GBA expansion?

[galneon]

I have an old M3DS Real Perfect bundle with a GBA expansion card (separate rumblepack). While obviously the M3 expansion isn't capable of rumble without switching cards, is there any functional difference between the two? In other words, any reason for me to get a 3in1? The 3in1 works with Acekards (including 2i) and R4s (including R4i Gold) from what I've heard and I'm not sure if my M3 expansion does... Do I need to get a 3in1 if I want GBA support for the 2i and R4i Gold?

it has information about the two GEPs.

If you have a question that isn't already covered by it, ask again.

Do I need to get a 3in1 if I want GBA support for the 2i and R4i Gold?

no, you will only need to use gba exploader if you want to use your M3 GEP.

Thanks! That answers everything. I started to read the "what version" thread yesterday but thought it was 3in1 only after reading only the part at the top. I'll grab a 3in1 anyway just in case my M3 ever fails.
