3DS Loader Replacement
|
||
|
|
======================
|
||
|
|
|
||
|
|
This is an open source implementation of 3DS `loader` system module--with
|
||
|
|
additional features. The current aim of the project is to provide a nice
|
||
|
|
entry point for patching 3DS modules.
|
||
|
|
|
||
|
|
## Roadmap
|
||
|
|
Right now, this can serve as an open-source replacement for the built in loader.
|
||
|
|
There is additional support for patching any executable after it's loaded but
|
||
|
|
before it starts. For example, you can patch `menu` to skip region checks and
|
||
|
|
have region free game launching directly from the home menu. There is also
|
||
|
|
support for SDMC reading (not found in original loader implementation) which
|
||
|
|
means that patches can be loaded from the SD card. Ultimately, there would be
|
||
|
|
a patch system that supports easy loading of patches from the SD card.
|
||
|
|
|
||
|
|
## Build
|
||
|
|
You need a working 3DS build environment with a fairly recent copy of devkitARM,
|
||
|
|
ctrulib, and makerom. If you see any errors in the build process, it's likely
|
||
|
|
that you're using an older version.
|
||
|
|
|
||
|
|
Currently, there is no support for FIRM building, so you need to do some steps
|
||
|
|
manually. First, you have to add padding to make sure the NCCH is of the right
|
||
|
|
size to drop in as a replacement. A hacky way is
|
||
|
|
[this patch](http://pastebin.com/nyKXLnNh) which adds junk data. Play around
|
||
|
|
with the size value to get the NCCH to be the exact same size as the one
|
||
|
|
found in your decrypted FIRM dump.
|
||
|
|
|
||
|
|
Once you have a NCCH of the right size, just replace it in your decrypted FIRM
|
||
|
|
and find a way to launch it (for example with ReiNAND).
