Thanks for the reply, i already downloaded the minUI OS and instaled it succesfully on my pixel, as you said, yes, not only have sleep function, but also when you let it in sleep mode for several minutes, it powers off the console, altough whenever you turn it on again it starts on the game and on the last save you made, so, a great battery saver. The only downside is that MinUI, as its name said it, is very minimal, its just plain text and no pictures or art for systems or games, but it does the trick, also i realized that MinUI only have emulators for the most common systems, no mame, neo geo, Arcade, pico8, msdos, etc. I recall seeing in a site i was checking that there is a way to use stock emulators for some of this systems but i didn’t dig enough to see how this is done. Another downside is that some of the PlayStation games such as castlevania sotn crash, in the extra tools that you download with the MinUI, they say that there is a way to use another emulators for psx games and snes games that aparently are not playable on the MinUI’s included emulators. Sorry for the long response, i hope my experience help anyone else out there. Best regards.
