Koriki for RG35XX Beta 0.8 has been released.

Per developer acmeplus, Beta version 0.8 of Koriki for the RG35XX is now available.
You can read about the changes in this latest version and find the download link posted here.

Koriki is a still in development custom firmware that combines the SimpleMenu front end with a fork of the GPU enabled firmware
from Batocera (in fact, it has replaced a cancelled port of Batocera to the RG35XX). While the RG35XX ships with a Quad-core PowerVR SGX544MP GPU onboard, it is disabled in the original firmware, and thus in Garlic OS. Seeing it enabled should give the 35XX a bit more juice.
