The original person doing the work is still developing Retroarch, but stopped adding new accounts to the whitelist (hence the previous deal was expired). Since then someone has started whitelisting again. So those that missed out last time can join the fun.
Xbox One consoles can play from NES up to PS1 games.
Xbox Series consoles can play from NES up to DreamCast, GameCube/Wii and limited PS2.
Basically you're making Xbox a RetroPie killer for free.
Instructions:
- Complete this form https://forms.gle/uigzj4RAUZw3pU839
- Check the gamr13s-announcements Discord room here to see when the next batch of Xbox accounts have been whitelisted (he generally does it every day).
- Once your account is whitelisted, go to https://gamr13.github.io using Edge on the Xbox and click on each to install the apps.
- Use the FTP app to copy over the required BIOS files and Roms (obviously these can't be linked to here and you should legally own these to do so).
Enjoy.
Make sure you check out DuckStation (either standalone or in Retroarch). Even the OG Xbox One can upscale PS1 game to 1080p at 60fps. It looks gorgeous.
Ignorant people were reporting the deal last time. To be clear from the start, Retroarch and Duckstation are open source.
