If you've already been playing your roms, is it unsafe to trim them? Will it mess with my savegames or glitch out? I've actually been putting untrimmed games on my acekard. I thought I remember reading a long time ago, before I got a flashcart, that if you already have a save file in a game, and then you trim the rom, it'll be unplayable somehow.
It's safe. Just avoid trimming roms that have been or will need to be patched, as generally patches require clean, unmodified dumps.
This makes things rather hard, as there's no real way for me to know whether or not a rom I have is pre-patched. From what I understand, a lot of romulation roms are pre-patched, which is there the bulk of my roms have come from.
im assuming that you want to trim them to save space on your micro sd, and that you have plenty of HDD space on your comp. Copy rom.nds Paste- Rename copy of rom.nds to rom_trim.nds Trim rom_trim.nds Test ???? Profit. As for save files, ive played a few untrimmed roms and used the same save files with the trimmed game later on.
Does anyone know where to get xtrim? The whole reason I brought this up is because I saw a topic about it, but the link is broken, and google isn't giving me any results except this one really shady looking website.

I forgot to come back and say thanks. So thank you It didn't trim them as much as I thought it would. I figured it would cut them in half. Some of them it trimmed well and others it barely shed anything off. Still, it freed up half a gig for me, so that's something. I should really invest in a 16gb, I thought 4 would be way more than I needed.
One byte under 50% is the absolute maximum amount of space you can save. If it wasn't, the producers would've used a cheaper, smaller game card. In most cases, the developers would rather pack as much data as they can fit, so you won't usually trim more than a few MB.
It's ok , So game's do trim more them overs do - depense on how much uneeded data are hex they is to trim Some game's can go down to half in size!
DS games are stored on cards with fixed capacities. If a game can't fit on a certain card, they put it on one the next size up, which is double the size of the last. The remaining blank space is filled with junk data. Trimming removes this junk data so the rom takes up less space.
