If you have one of the untested devices, or have tried slot on a device not listed,
please [open an issue on GitHub](https://github.com/BrandonKowalski/slot/issues) and let me know how it went.

## RG28XX Users
RG28XX support was contributed by [GamerAnim](https://github.com/GamerAnim). The RG28XX has its panel mounted in a
portrait orientation. slot turns the picture to fit it, but on some units it comes out upside down.
If yours does, open `System/launch_frontend.sh` on the SD card and add `export SLOT_ROTATE=ccw` just
above the last line:

```sh
export SLOT_ROTATE=ccw
exec /lib/ld-linux-aarch64.so.1 "$SYS/slot" > "$SD/slot.log" 2>&1
```

# AI Disclosure

The Rust frontend was put together by Claude Opus. I reviewed everything that was
produced. All documentation is 100% free-range, meatbag prose.

The project is extremely low stakes. I wanted a bespoke frontend for my RG SP and thought
that something that evokes the feeling of using my GBA SP as a kid would be pretty neat.

Use it, don't use it, I don't care.

Figured I should share the end result of all the wasted water. ✌🏻
