Is there a safe ROM trimmer for the GBA? I don't want anything that messes up my files.
No, there isn't. GBATA and BatchGBA are the safest I know of, but they can still cause problems with some roms. In my experience, GBA roms are far more likely to have problems or not run after trimming than DS roms.
You don't save nearly as much space trimming GBA roms as you do with DS roms, so I don't even bother.
Every game I've trimmed worked fine for me, but perhaps that's because I'm still using a Flash2Advance Ultra cart (and play very few commercial games).
If you're into Puzzle League however, note that you can actually chop off all the data past the 2.2 MB mark (a huge block of zeros marks the location when viewed in a hex editor) from "2261 - 2 in 1 - Dr. Mario and Puzzle League" and still have a fully functioning Puzzle League game. Dr. Mario will be borked, but that's not as important. It's nearly a 75% reduction in size, which I find pretty cool.
Yeah I noticed it barley saves any space so it wouldnt really be worth it if it could have problems. I had 300 or 400mb of GBA and only trimmed of like 20mb.
My guess is that since the type of ROM used in the GBA was so expensive, if a developer had to upgrade the cart capacity they felt they needed to use up as much as possible.
or the files just arnt that big in the first place.
You could try my trimmer NDSTokyoTrim, last version is ( I think ) safer than GBATA and BatchGBA
