# Standalone payload.elf loader
This is .rpx is meant to run in a envrionment with sd and codegen (jit) access.
It's exploits the Cafe OS and maps 8 MiB of usable memory from 0x30000000...0x30800000 (physical address) to 0x00800000... 0x01000000 (virtual address) where a payload will be loaded. You may need to hook into the kernel and patch out some thing to gain persistent access to this area.
The loaded `payload.elf` needs to be mapped to this memory area.

## Usage
Put the `payload.elf` in the `sd:/wiiu/` folder of your sd card and start the application.
If no `payload.elf` was found on the sd card, a IOSU exploit will be executed which forces the `default title id` to the Wii U Menu (in case of `system.xml` changes)

## Building
Make you to have [wut](https://github.com/devkitPro/wut/) installed and use the following command for build:

```
make
```

## Building using the Dockerfile

It's possible to use a docker image for building. This way you don't need anything installed on your host system.

```
# Build docker image (only needed once)
docker build . -t payloadfromrpx-builder

# make 
docker run -it --rm -v ${PWD}:/project payloadfromrpx-builder make

# make clean
docker run -it --rm -v ${PWD}:/project payloadfromrpx-builder make clean
```
