Gaming Trimming NDS games makes them lag?

[prowler]

I /acquired/ alot of games and I trimmed nearly all of them with TinyTrimmer and ever since then I've been noticing some lag on games.
Is this why they are lagging?
Also this is abit out there but is there any way to 'un-trim' them? If not, I'll just go re-acquire.

EDIT: I would choose best answer for both Overlord and GH0ST so if anyone is reading this trying to find the same thing out, read both posts :3

I don't think trimming has any effect on games lagging or not (after all, it's just some 'empty' data that has been taken away, it's not like ISO/CSO, where CSO also compresses that data).

I don't think it's possible to untrim a rom, because the software would have to know whether it's all 0s or Fs that are there. Just redownload the game, if you really want an 'untouched' ROM.

No Perhaps the lag is related to low free space or fragmentation of your card ?

Trimming is harmless when safe, only useless blank end data blocks are wiped.

TinyTrimmer is safe except for few games which might have problems with the trim option:

The size of the rom is written down at 4 bytes in the nds header and trimming to that size+136 bytes (for wifi data) is safe in most cases but some games ( 0040, 0132, 0192, 0318, 0357... ) MISS OR FAKE THIS VALUE.

Trimming 40 Hanjuku Eiyuu DS - Egg Monster Hero (JP) leaves only 136 bytes ... just to let you know about this bug in TinyTrimmer.
