ROM Hack How do you extract files from a .dat file extracted from a 3DS game?
If they're anything like the .bin files in Tomodachi Life, you should be able to open them with Every File Explorer.
here's another python script to extract all the images out of the bch files. It's probably going to take a while to extract all 12,000+ images, but it'll do it. Good luck translating this game, it looks like a LOT of the text is in the images.
The script can be called from the command line like so:
right now it only converts the bch to a .png. I haven't gotten a chance to write the code to convert .png to .bch
Also, it currently only handles the 3 image formats that were found to be used, which are ETC1,ETC1A4, and RGB565.
ETC1/ETC1A4 decoding relies on etc1Util.exe, which is pretty much just a hacked up version of smealum's etc.exe, I'll post the source to that on github when I get around to it.
etc1Util also only decodes at the moment.
to convert all the bch files(all but 1 of them anyways, 1427.bin doesn't actually have an image as far as I can tell), you can create a quick .bat file like so:
Again, it'll probably take a while. I imagine that half of what slows this script down is the reliance on etc1util, however, I'm not about to try to re-write the etc1 decoding in python, and I didn't feel like writing the bch converter in c++. One of these years I'll get around to writing a python module(with matching .dll) that'll handle conversion to and from common 3ds pixel formats, if someone else doesn't beat me to it first.
The script can be called from the command line like so:
Code:
py aceBCH.py -e 0.binAlso, it currently only handles the 3 image formats that were found to be used, which are ETC1,ETC1A4, and RGB565.
ETC1/ETC1A4 decoding relies on etc1Util.exe, which is pretty much just a hacked up version of smealum's etc.exe, I'll post the source to that on github when I get around to it.
etc1Util also only decodes at the moment.
to convert all the bch files(all but 1 of them anyways, 1427.bin doesn't actually have an image as far as I can tell), you can create a quick .bat file like so:
Code:
for %%x in (*.bin) do py aceBCH.py -e %%x
Sorry to bump.
etc1Util crashes, can I use smealum's one? (Or could you release the source code of yours?)
Also, have you gotten the repacking to work?
hello i want to translate this game the seven deadly sins unjust sin i was able to extract the cia files and now i have dat and pck files could help me please extract them here is screenshot for the files and i uploaded two files maybe will help you

How did you extract your .dat file? I'm trying to use Dsdecmp but I don't know how to use it. The instructions aren't clear.

Or, I also heard that if you use flash memory, it can act as more "RAM" at least windows tell me when I stick a flash drive into it. -

I can think of the design teams process another joystick and no audio or a joystick and mono audio -
