Gaming Is it actually a good idea to trim ROMs?

[thedicemaster]

And the new Warioware, it trims it from 128MB to just 16.5!

Just checked and this is accurate. Now, would anyone care to explain why this is so?
I thought trimming removed the empty packed space of a rom, for eg. if the game data was over 65,536 KB, then it would need to to go to next size rom of 131,072 KB. Therefore, any trimming would only reduce it to something over 65,536 KB. But this game's rom has been packed with approx 115,000 KB of empty space....correct?

if i understand correctly, DIY doesn't use a standard model gamecard.
instead it uses one with extended save-storage(32Mb i think?)
they wouldn't want to waste time developing several types of 32Mb-save gamecards because very few games would ever need that much save-space, so they made a "one-size-fits-all" gamecard that could pretty much house any game that needs 32Mb save space.

just trimmed 728MB using TinyTrimmer. 5 seconds for 61 games

There is a trimming option in akAIO for acekard. Has anyone tried it?

It has to do with the way the ROMs are dumped you can only dump a ROM at a set size now there is much biggger games and they are being saved as 128mb files so it the rom was dumped as a 128mb file even though it only is about 16 mb

No, when that happens it's known as an "overdump" and is considered a bad rom and a redump has to be done.

With warioware DIY, it really is 128 megs of mostly empty data, which is why people are so curious.

Your Correct. It seem like the dumpers round the ROMs to 8MB, 16MB, 32MB 64MB Etc.

 

[Rydian]

That's the actual size of the game carts IIRC, which is why the ROMs come at that size (untrimmed).
It's flash storage so it's done by powers of 2.

Usually a ROM will be in the smallest size cart type that it will fit in, which is why DIY's got people scratching their heads.

 

[suruz]

Is dsbuff okay for trimming roms? That's how I trim mine because I don't really use the wi-fi features on many games...

Not the dumpers, the manufacturers. Carts are a set size. Look at it this way, if you made a game and it was 400meg you could put it on a 700meg CD, if it was 1.2gb you'd have to put it on a 4.2gb DVD, if it was 7 gig you'd have to put it on a DVD 9, etc. Dumpers dump the whole cart, and that emans you get 8MB, 16MB, 32MB or whatever of numbers, even if x amount of those numbers are 0s, the blank data left at the end of the cart.

I've been using NDSTokyoTrim for a long time now without issue, but I may give TinyTrim a look.....if it really is faster and easier to use.

 

[missfabb]

i just tried tinytrimmer(i don't usually trim my roms). i saved 412mb! oh joy(:

 

[YayMii]

I've never trimmed my games (I was always cautious because I often patched my games). Today, I trimmed my 5.5GB of ROMs (using TinyTrimmer) and managed to save 730MB of space.

You really never trimmed any of your ROMs before

If you were worried about patching, you could have just not trimmed the ones that needed patching until after.

QUOTE(DeMoN @ Mar 25 2010, 11:42 AM) Does anyone know how good the built-in trimmer for the CycloDS EvoTools is?
And do any of these programs work on a 64-bit computer?

Yeah, I was using until just a few hours ago, it's pretty good but doesn't trim certain games(such as ACII).
Now I use both TinyTrimmer(more thorough) and the Evo Tools(automatic) one for maximum effect!!

 

[Dangy]

I have TinyTrimmer ON my MicroSD, I use it for all my games. D

 

[Primenay13]

Yes I do and it saves lots of space

i tried it on wario ware DIY and it works fine

 

[sn0wfish]

personally i dont trim my roms.. i just take out the game that i play the least to get something i want, on it

 

[iYoshi-]

Last time i trimmed, a few of my games stopped working, i dont really need to trim seeing as i only have a few games

I presume you tried trimming DSi Enhanced games? Because those should be the only ones giving problems after being trimmed, they don't work anymore and just give white screens while loading. Other games should be fine.

 

[Rydian]

I used TinyTrimmer, and Assassin's Creed 2: Discovery still works, it's DSi enhanced. Haven't tried others yet.
