Quotes from users over at gbatemp.net:

– Only NDSTokyoTrim should ever be used in my opinion.
– just use the best trimmer, “NDStokyotrimmer” it’s the obvious best & fastest trimmer, NEVER had a single problem with it.
The best rom-trimmer out there for the NDS is without doubt NDSTokyoTrim

– Option to rename files to remove scene numbers. (like “0123 – abc.nds” -> “abc.nds”)
– Option to check for existing files (to avoid overwriting) with “different output folder” option
– Extremelly improved GBA trimming routines, ~10x faster
– Fixed and improved GBA SRAM patching routines

– Added SRAM patching for GBA roms. Note: this is experimental, please post about any errors in the gbatemp forums
– Extremelly improved GBA trimming routines
– fixed: dragged compressed roms didn’t enable the trim button
– added save log button to the expanded log window
– Ability to disable the background or use custom ones from a random list (or fixed one)
– Added command line option to import 1 compressed or uncompressed rom (drag to the .exe or use open with..)
– Alpha blending slider (window transparency)
– Faster start-up
– Fixed savings counter which was limited to 2GB.
– Fixed compatibility with win9x and Linux (wine)

– 7zip support
– GBA roms trimming added (not throughly tested)
– automatically check for new versions
– lots of improvements and small fixes in the output location and file search routines
– auto detetion and fix for improper trims from other applications
– very basic brick checker (theorical and untested)
– sligthly faster
– NDS roms header info (select an uncompressed NDS rom and right click or click the chip button)
– DLL files for RAR/7z support are loaded straight into memory, so you won’t see the dll files extracted to disk anymore

– RAR Support*: scan for roms inside of RAR files. Overwrite method preferred (it won’t delete the rar)
– Ultra-fast new overwrite method: use overwrite to trim roms in as low as 0.01 seconds.
– Move the window around by clicking anywhere on the listbox or empty window area. (EasyMove)
– It now remembers your Input and Output folders in the file dialogs
– Command line options: drag a folder to the exe to have it scanned on start-up automatically
– Option to stay Always On Top
– other minor fixes

It should be a lot faster now, specially when loading/saving to flash memory devices.

small bug fix


Fixed a problem with some roms that are originally dumped in a wrong way. It should work with all now. If you had some roms with errors after trimming, please re-trim them now. Also added an expanded log window.

You can select the files to scan from the box

Options are saved to registry.

Fix a bug with drag&drop not seeing upper case .NDS filenames

Drag&Drop support for files, zips, folders.

Scan inside ZIP files

    “Krojamsoft BatchRename” Tool is a powerful tool, that allows you to quickly rename all the files in a specified directory. You can remove spaces, replace spaces with underscore, uppercase/lowercase filename, add a prefix/suffix, remove/replace strings and also catalog files by adding an incremental number to the file name.

    Incorrect File names? Just use “BatchRename”. Fell better using computer.

    So, trying to download this, it can get to 99% and then I lose the connection to the server, I’ve established that my antivirus isn’t causing it, I’ve tried straight browser downloading and even with an external download manager, the download just straight fails at 99%

    I can’t trim some of the GBA roms (example: Mother 3 (Japan)). I used v2.5 of NDSTokyoTrim.

    Hey i would like to report that the 2.5 Beta version deletes the Wi-fi part of Tetris DS.
    Fix it in the next version.

    Worked it out, I had to add it to Win7 DEP exceptions o.O I had forgotten I had it enabled for something, and forgot that TokyoTrim needed DEP disabled. Sorry for the trouble, guess I haven’t had a good tech week.

    I can’t reproduce the error. What’s your UAC level?

    No word for a week? Not good for a useful piece of software, that is possibly the most used pc app for the DS. Not liking this, not at all. Been using this since I got my first Slot-1, however long ago it was.

    Pokémon – White Version (USA) & Pokémon – Black Version (USA) don’t work with 2.5 beta, but work with 2.18

    Do you know if this issue has been fixed with the new Beta as I’m reluctant to trim with anything but 2.18.

  26. April 7th, 2011 at 20:09 | #26

    fixed in new beta.

  27. April 6th, 2011 at 13:31 | #27

    Thanks for the report, will look into this asap.

    v2.5 beta breaks some roms after trimming. Here’s one of them:
    (tested on AK2i w/ AKAIO 1.8.6a)

    Emily the Strange – Strangerous (E) – 64.0 MB/67,108,864 bytes

    After trimming (v2.18) – 53.6 MB/56,250,368 bytes = working
    After trimming (v2.5 beta) – 52.5 MB/55,133,320 bytes = not working/white screens

    Still violates DEP and will not run on systems with it enabled for normal programs until it is manually added to the whitelist.
