This removes the need for Jig and booting into RCM mode, or have to use a computer to inject a payload. That way you just shut down Lakka when you're done, and just insert the payload dongle when you when to boot it up again. There's a kind of work around for sleep mode at the very least - the best experience you get with Lakka currently is by using AutoRCM and a payload dongle. There's a build as recent as May using almost all up-to-date cores except for N64 which is just a version out of date. Thankfully users here have done that and posted this recompiled builds. With that said - it's possible Lakka will continue to get some of it's cores updated as time goes on - but in order to do that it has to be recompiled which can be a complicated process unless you have knowledge on how to compile software. The original author has stated they do not plan to update it anymore. Its unfortunate but unless someone else picks up the project you can't expect Lakka to gain new functions like sleep mode. It doesn't run it very well for the vast majority of games, however it does run better then OPs detailed experience so there is at least something wrong here. You shouldn't really use Lakka if you're looking to play GameCube. If you're having issues you most likely had a slow speed SD card, or running games at too high a resolution, or have not found the right GPU / CPU clock settings (Don't go over + 3 for GPU). PSX runs 100% fullspeed in Lakka with over 30 games I've test.

Gouchi, the actual developer of Lakka, said this in the link I posted too.

The cores folder is blank if you open it, and if you put a core in it there's no way to install or add it to Lakka because the option is disabled. Manually placing a core in the "core" folder generated by Lakka doesn't function. This works in Horizon OS, and Switchroot, but not with Lakka.

You can't update cores, or manually add new or updated cores in Lakka - please stop recommending that - it will confuse other users.
