    I'm thinking of trimming some of the backups I have and I am wondering if that drops the quality of the game if at all. The reason for this is because I obtained two different backups of Portrait of Ruin. One was about 20MB smaller than the other but the smaller one had some missing sound than the larger one.

    Is this an isolated case or should I leave them as is?

    i would stick to NDSTokyo Trimmer. But trimming rarely affects gameplay. It may break wireless connectivity once in a great while but if u find a rom that does that, then just leave it untrimmed.

    That copy of PoR that you found was purposely hacked to remove some of the sound files. This was done to prevent the game from freezing when played from slow cards.

    When a rom is trimmed properly, there is no difference other than the file size. I recommend NDSTokyoTrim for trimming DS roms.

    I think when Portrait of Ruin first came out and it wouldn't work on most flashcarts, some people hacked the rom to remove various things like sounds and music so it would work better. That smaller rom you have may be one of those.

    EDIT - Ah, Destructobot beat me to it.

    Destructobot is too fast; beats everyone. [​IMG]

    Anyways, just use NDS Tokyo Trimmer. Trimming really shouldn't affect gameplay at all.

    Alright thanks. I think i'll try that trimmer program you guys mentioned. Another question. If i trim a game I'm already playing, will it affect the current save file for that game?

    Not at all. It just reduces size of the ROM file.

    All a trimmer does is remove empty data at the end of the file. If you open up the file in the hex editor, you'll see pages and pages of "FF" or "00" at the end of every untrimmed rom file. That's empty data that does nothing but take up space. As long as you use a good trimmer, you don't need to worry about anything screwing up.
