Tempest for the 3DO with 3DO mouse support
This is Tempest 3DO developed by Home Brew expert Retro Love letter : / @retroloveletter . You can download the ISO and play this yourself here: https://github.com/retroloveletter/tempest...
I played this on my modded Japanese FZ1 with the Fixel ODE.
The game plays really well with the 3DO mouse and the music is fantastic.
