ROM Hack GBA Rom size

[leinad]

Uhm, yeah: its just a small question

Is there any info about the size of a GBA-Rom INSIDE the rom ?
So just think of it if I would have a "rom" which is 64MB [=wrong size] and I want to find out the proper size

The best place for info on GBA files is http://releases.pocketheaven.com/ - just use the GBA search engine to look up the name of the game.

BTW, all ROM sizes are in Mbits (Mb), not MBytes (MB). 8 Mb = 1 MB

You can trim GBA roms with GBATA or NDSTokyoTrim, if that's what you're getting at. It doesn't save nearly as much space as trimming DS roms though.

The "proper" size is the power of two. The amount of actual data compared to this power of two varies from game to game. Destructobot basically nailed it. Grab a timmer app and it will remove as much space as it can, and that will be what you consider the "actual" size.
