    The tool comes in the CD that comes with your M3 Simply, so don't worry about it too much.

    I'd aussume that the m3 trimming tool is the same as the r4 one. There's a bit of discussion here:

    http://gbatemp.net/index.php?showtopic=41527

    That suggests it overtrims - the conclusion is that it might be safer to use the dsx trimming tool.

    trimming removes the empyt space in a dumped rom therefore making it smaller. It will not affect the function of the game

    DS roms (and nearly all roms for other systems for that matter) are dumped to match the size of the save chips used (8, 16, 32, 64, 128... Megabytes) and naturally the code does not have to take this all up (some like Snowboard Kids (US) are nearly half junk). The remaining bytes are filled with 00s or FF's (sometimes alternating between the two) and these can usually be safely erased (sometimes a 00 or FF is used to end a file, line, picture.... and this can mess it up).
    Now with these drag and drop onbard patching carts then there is no client phase that can trim the rom and everyone seems to want to squeeze every drop of space so people are searching for trimmers to use.

    As for me I still use a GBA slot cart so I am not bothered by this but:
    Purely as it reads 7zip and select any and all roms I want I would use offline lists trimming function, GBATA can take care of anything else.
    People that are curious check out the DS rom ripping and enhancements link in my signature as that is a damn easy way to save space as well (you can replace the movie on Castlevania and half the rom size, you can rip out the Euro languages you do not need on Nintendogs and save yourself a nice chunk of space and of course you can replace sound files to either save space or improve the game.

    Out of curiousity does anyone know if there is a DS rom trimmer (the start of the 00/FF section is contained within the header)?

    edit: far too slow

    Trimmed about 40 games with the R4 trimmer and never had any problems with any game, so I wouldn't really worry about overtrimming.

    I personally use the DS-X trimmer because you can do batch trims, which makes it ALOT more efficient than using the R4/M3 trimmer.

    There are a load of batch trimmers out there. And if you have .NET installed, go ahead and look at the homebrew section, there is one listed there with a DLDI patcher AND trimmer integrated. Very cool!

    here you go!:

    When I try to trim Dragon Quest Rocket Slime with your great trim-tool, nothing happens. Your trimmer doesnt do anything...
    No errors, but there doesnt happen anything...

    You might find me crazy but I trim my ROMs by hand with a hex editor [​IMG]

    Maybe I'll make myself a nice script in perl for my bday [​IMG]
