R4-SDHC ROM Trimmer 2.0
Because the capacity of NDS cartridge has
a fixed standard, such as 128Mb, 256Mb, 512Mb and
1Gb etc, So the capacity of the Dump has the same
standard: 128Mb, 256Mb, 512Mb and 1Gb(They will display
on the PC like this: 16MB, 32MB, 64MB and 128MB, 1Byte=8bits).
Every game has their capacity, which is
not exactly the same as the standard. Supposed that
the game has a 300Mb capacity, it needs a 512Mb game
cartridge to run, and then the other 212Mb is redundant.
The R4DS ROM Trim Tool can delete the redundant data
to save the space and also keep the game running well
according to this theory.
There is a pop-up window displayed after
running the software:
There are two textboxes, the top one for
inputting the NDS/IDS game files, the '...' button
can do a convenience browsing if you can't remember
the file name and the path. Choose the correct input
file type by clicking the pull-down menu according
the ROM, which need to be trimmed. Please remember
that .nds is extension of the NDS game and .ids is
extension of the IDS.
The bottom textbox is for outputting the
trimmed ROM's file (When you choose the input file,
it will generate one automatically). You can change
the output path if you need; default is the same as
the input path. The '...' button can do a convenient
To start processing trim tool by clicking
the 'Start' button once every thing is ready, a pop-up
window will display the processing status.
You can see the difference between the trimmed ROM'S
file and the original file, (0%-50% trims will be
available according to the different ROMs.)
The Trimmed ROM can be copied and run on
the SD/TF card directly!
Tips: The processing on
the hard disk will be faster than processing on the
SD/TF card as the hard disk has the higher read/write
