Hacking can I compress ROMs?

[snake2]

I just got a DSTWO and was wondering if ROMs need to be .NDS files or if I can compress them into either a .zip or a .rar file. or is there is a program like wii scrubber to remove unneeded data

 

[ShinyLatios]

yep, there's a program for it. its called tokyotrim! google it, you'll find it

They need to be NDS.

You can trim them (same sort of thing as scrubbing, reduces the size), how much a game gets reduced by varies widely and depends on the game.

Find 'tinytrimmer' on FileTrip.net
Find 'ndstokyotrim' on FileTrip.net

will trimming the rom affects the game?
i already know about this but i never tried it..

Most of the time trimming doesn't affect a rom, but on some games you may run into problems with multiplayer.

oh i see.. hmmn... how much discspace do you save after trimming a rom?

 

[Rydian]

1 - 100MB.

Depends entirely on the game.

Just rim it yourself, it's not really a hard process. If you don't want to trim it because you fear you'll lose your rom in the process, then don't fret, most trimmer leave a backup of the original rom (I can assure you NDS Tokyo Trimmer does). As Rydian said before, the amount of junk that's trimmed off depends on the rom; I know Pokemon White got a good 50MB off.

thanks guy.

@Totoy_Kamote I trimmed golden sun it was 256MB and trimmed to 212MB I have not tried the trimmed version yet

1-127MB actually... this is of course pending a 129MB game taking up a 256MB chunk. Btw, "NDS ROM Trimmer" is a really good ROM trimming application for anyone on a Mac (works with both Intel and PPC based Macs.)

 

[Lassik]

When trimming a rom that you intend to use on a DSTWO, do you know if it is required to run the rom in "patched" mode or will it still work in "clean" mode?

I mean as far as I know, patching and trimming are two different things so I just wanted to be clear.

Well if you want to get technical there's 512MB games out too.

Ninokuni: Shikkoku no Madoushi is rumored to be 512 MB, but it's not scheduled for release until 12/09/2010 in Japan only. I can't think of any DS roms that are currently this size untrimmed.

You can reduce the size by about 50MB for GSD
