help finding a gba expansion pack

[DanTheManMS]

There are 8 bits in a byte. The largest GBA games are 256 MBits, which is 32 MBytes, and this is the amount of NOR flash the 3in1 has. The 3in1 also contains 16 MBytes (128 MBits) of RAM which can also be used to launch smaller GBA games if you wish. RAM is much quicker to write to, but its contents are lost after you shut off the DS, so you must load the game to RAM every time you play (saves are handled separately). NOR flash is very slow to write to, but once you write to it, it acts just like a GBA cartridge and you don't need to overwrite it again. You could take it out and put it in a GBA and play the game if you wanted to.

Basically, RAM is good if you have a lot of games you play and swap out often. NOR is good if you want to play a single game extensively. The largest GBA games will only fit in NOR, everything else will work in both NOR and RAM.
