Probably. Warioware and Zero Mission both work. I haven't tried Fusion. The vast majority of GBA roms do work.

The manager assigns icons based on the rom name if the file header, and it chooses wrong or doesn't find an icon quite often. I reccomend switching to small icon mode in the G6 GBA options. This will give you a list without the pictures.

The G6 displays the rom name from the file header, not the file name. You can change the name in the header with a hex editor, the
Flash Advance Toolkit, or a number of other programs. Every rom you change the rom name for will get the G6 icon instead of the one for the game.

Metroid zero mission works with the default settings (no real-time saves, no trimming, hardware+software patch).

Real-time saves are known to cause compatibility problems, it's recommended not to use that option.

If you aren't using real time saves you can delete the real time save files (.is0 .is1 & .is2) from the GBA folder on the G6. This will probably free up a lot more space than trimming would; about 1.5 megs per game.

Yea, that's real space saver if you dump these files. Especially if you play lots of gba on the g6.

yeah, i delete all the RTS and the .1 and .2 saves, so i only have 3 files per game

Just wondering, after the game name, u get a random 4 or 5 string of letters, like ABSE or something like that
can you get rid of this?

Not that I know of. The GBA loader seems to think that the rom name in the header is four letters longer than it actually is, and they don't seem to be in any hurry to do any work at all on the GBA side of things.

You could try replacing the four characters after the rom name with a hex editor and see if the rom still works, but I don't think it would be worth the trouble. Other than that, just deal with it.

I just now tried using a hex editor to overwrite those characters with spaces. The characters were gone from the G6 menu and the game (SMB2) still loaded & played. I'll try more games later.

soo, you just deleted the for characters, and then inserted spaces, as in pressed the spacebar 4 times?
cus i replaced them with for . thinkin that was just a space, but it didnt work

The rom name + the four characters = 16 characters total.

In the text side of the editor I selected the character after the last letter in the rom name, and pressed space until the end of the 16 characters.

Code:
The name showed up as "SMB 2 ÌÌÌÌÌÌABSE" (or somthing similar) and I changed it to "SMB 2 Â Â Â Â Â "
I just tried it with SMB 3 and it also worked.
