Wait and hope we can get the later Kernel and vulkan to work. Or for notime2d8 to release Android which has vulkan.

From @afro_toast from RG Handheld discord server:
"also, by default, even in theRA the right stick is mapped wrong for dolphin, so here
https://www.mediafire.com/file/lbb8lcd7 ... s.zip/file
fixes the right stick configuration, disables threaded DSP(which screws with audio), and enables all three desync options, which will unlock variable framerate on a bunch of the library. whatever stutters and performs poorly with this config can't really be helped unless you play with custom gamesetting files and underclocking."

Hello crashoverride, could these optimizations be incorporated into the next firmware update?
Coupled with an overclock to the max specified values, these changes significantly improve the emulation performance of Gamecube.

A note to anyone who wants to play GameCube games, using the above changes paired with PAL roms makes several games fully playable.

The settings will be included in the next release. The only modification I made was to disable the FPS counter display.

Is it possible to reduce the resolution on the emulator? If so how/where? :lol: For example the Retroid handheld emulates gc at 0.5x resolution out of box (looks awful, but runs smoothly)

The only setting I am aware of increases the internal resolution.

I have re-written the presentation interface to tripple-buffer it. However, this only increases the FPS by four (4) in informal tests. I plan to include this change in the next release.
