Building PlayBrew Loader

Windows

Prerequisites

• The Arm-None-Eabi-Gcc compiler (It is deprecated, make sure to get downloads from that page, specifically version 10.3-2021.10. The newer non-depricated version does not work to my knoledge)
• CMake
• MinGW
• python

Building

clone the repo
Then place your decrypted pdfw-b firmware file in the root directory next do the following commands:

cd build
echo i need to look at my laptop to get the command that go here :D
mingw32-make
cd ..
py combine.py

Combine.py will ask for your rev, currently rev A isn't supported so do B.
Then get your pdfw-b-patched from the build folder and install it by opening the boot disk, deleting VERSION.txt, moving your new fw to the disk, and then renaming it to pdfw with no file extension before ejecting.

Todo:

  • also need to save annotations in Ghidra more so I can understand wtf I'm actually looking at
• add extra functions
  • screen drawing access -- In Progress
  • input access
  • more filesystem access
• make installer CFW and don't get DMCA'd
• find a way to add a custom menu item to open PBL so you don't have to restart
