They should make that thread sticky, it's really useful for playing some 1Gb games on a 512Mb MicroSD.

it don't seem to work in 64bit windows is there a version that does? i was thinking of have a dual boot on my laptop 32bit and 64bit but seems a little extreme

Just get VirtualBox and throw a trimmed version of Windows XP on there.

It works fine. Are you sure you know how to handle apps without GUI? Use full path to files and .exe's and make sure there is no spaces along the way.

I have never used an app without a GUi so took me while to figure out but all working now thanks

I'm adding 3DS support to my trimmer, new version 3.0 will be out very soon (sometime this week).

Will it trim Card2 games especially the VC games?

Can you point to any for checking?

What do you mean?

For instance, can it trim Pokemon.Yellow.GBC.VC.3DS-BigBlueBox to a much smaller size instead of just 64mb

Ok I will check with that one. Trimmed size can be max ~50% for any rom.

Not for VC games. They can be trimmed to approx 5mb but somehow saves won't work. If you can make it trimmed to about 10mb and have saves working that will be awesome

It's possible, it just involves more modification of the header than most games... I have one trimmed GBC rom that is like 7 MB's, and it loads and saves fine.

Is there some tute on how to do this?

Not that I know of. I tried doing it myself and it didn't work. The one I have is Super Mario Deluxe that I was given as a test, I didn't do the modifications myself.

Card 2 games shold be trimmed differently. Somebody made a tool for that with src Super.Mario.Bros.Deluxe.EUR.VC.3DS.INTERNAL-BigBlueBox

Yes but it can only trim a GBC VC rom to 64mb smallest. I'm talking about trimming it down even more

Update:
Looks like the game will stuck during initializing save data the first time you run it after trimming (but the second time will load fine). Don't know what's the problem.
The tool is updated, now you need existing and valid save data to skip save initialization. You need to load the rom at least once before trimming. The tool will automatically scan for existing save data and transfer it to the new save offset before trimming.

Seems like quite a nuisance if you need to first load the untrimmed rom once.
