# Mocha lite - a simple custom firmware
This a lite version of the [original mocha](https://github.com/dimok789/mocha) to be used with the [SetupPayload](https://github.com/wiiu-env/SetupPayload).
## Usage
Place the `00_mocha.rpx` in the `sd:/wiiu/modules/setup` folder and run the [SetupPayload](https://github.com/wiiu-env/SetupPayload).
## Patches
- You can also place a RPX as `men.rpx` in the `sd:/wiiu` folder which will replace the Wii U Menu.
- RPX redirection
- overall sd access
- wupserver and own IPC which can be used with [libiosuhax](https://github.com/wiiu-env/libiosuhax).
- Opening the "Health and Safety" application will try to run the [Homebrew Launcher](https://github.com/dimok789/homebrew_launcher/) from `sd:/wiiu/apps/homebrew_launcher/homebrew_launcher.rpx` from sd card.
## Building
For building you just need [wut](https://github.com/devkitPro/wut/) installed, then use the `make` command.

/* Patch for MCP_LoadFile (ioctl 0x53).
* Also adds a sibling ioctl, 0x64, that allows setting a custom path to a main RPX
*
* Reference for most of the types and whatever:
* https://github.com/exjam/decaf-emu/tree/ios/src/libdecaf/src/ios/mcp
*
* This is a proof of concept, and shouldn't be used until it's cleaned up a bit.
* Co-authored by exjam, Maschell and QuarkTheAwesome
*
* Flow of calls:
* - kernel loads system libraries, app rpx or user calls OSDynLoad
* - goes to loader.elf, which will call ioctl 0x53
* - with fileType = LOAD_FILE_CAFE_OS
* - on failure, again with LOAD_FILE_PROCESS_CODE
* - on failure, again with LOAD_FILE_SYS_DATA_CODE
* - each request routes here where we can do whatever
