How many games fit on a 256Mb cartridge?
Commercial GBA ROMs typically fall into one of three size categories; 32Mb, 64Mb, and 128Mb. Therefore, you can typically fit 2-8 commercial ROMs on one 256Mb EFA cart. However, PD (Public Domain) ROMs and NES ROMs (which can be bundled into GBA ROM files using PocketNES) are very small, so it is possible to put dozens of these on one 256Mb EFA cart. Even if you have large commercial ROMs, it is so easy and fast to format and rewrite the EFA cart, it’s not a big deal to be limited to a few at a time.
