Time for an article I wrote about Slot, an interesting custom firmware made specifically for the Anbernic RG SP. I chatted with its developer K-Wall about where it came from and why it deliberately does things a little differently.

Rather than trying to turn the RG SP into an everything-machine, Slot sticks to the Game Boy family and leans hard into the SP nostalgia: games appear as physical cartridges on your screen, the carousel encourages you to keep a smaller collection, closing the lid saves your game, and even the old stretched GB/GBC display mode is recreated. K-Wall took that attention to detail right down to the sounds, recording himself physically pushing a cartridge into his childhood GBA so that familiar 'thunk' could become part of Slot itself.

We also chat about burnout, his other projects Cannoli and Grout, why Slot started as something he never intended to release publicly, and his very candid approach to using A.I. during development as a tool. If you like the RG SP, unusual CFW projects, or software designed around a very specific bit of hardware rather than endless feature creep, hopefully you’ll enjoy it :)
