entry point for patching 3DS modules.
## Roadmap
-Right now, this can serve as an open-source replacement for the built in loader.

+There is 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.
+This currently requires recompilation which makes it less than ideal.

## Changes I've made
The text, data, and ro segments are handled separately to streamline the new
segment resizing and limit search space to speed things up a tad. Why search
-text, data and ro when you know it is in text?
+text, data and ro (big) when you know it is in text?
## Imported changes from other 3ds_injector forks
I updated it to the latest git ctrulib (in which FS_Archive is a u64,
-not a struct.) @TuxSH did the work before me, it required manual conflict merges
-but he provided the information needed to fix it up for the most part. ;P
+not a struct.) @TuxSH did the work before me, although it required manual
+conflict merges since my tree differs a LOT from both @yifanlu and his
+version.
## Build
You need a working 3DS build environment with a fairly recent copy of devkitARM,
ctrulib, and makerom.
-Currently, there is no support for FIRM building in toolchain; whatever method
-you use to inject this is up to you, but the software must have support for
-resizing the sysmodule segment, or you must make sure the module size matches
-the original.
+This is not intended to be used with anything but corbenik, so please don't use
+binaries of this with any other CFW. For devs - message me if there's any changes
+you want help merging. I'll be glad to help. I'm not into anti-competitive
+behavior. ;P
