It could be a big deal if the developers of GarlicOS / OnionOS support it. I have a Retroid 3+, a Miyoo Mini (lost it) , and now an Anbernic GBA SP.
The Retroid seemed amazing at first but after using a Miyoo with OnionOS, I’m not going back to Android retro gaming.
The usability of being able to pick up a hand held and play immediately cannot be understated. Android doesn’t normally shutdown. It sleeps which means it only lasts a few days (not being used!) without being plugged in unless you explicitly pick power down from the menu. If you do power down, it takes over a minute to boot. The Android retro front ends also take hours and hours to setup.
OnionOS/GarlicOS completely power down so the battery always has charge and is ready to go. Because there is no Android, boot to being back in your game (it defaults to powering up right back where you left off in a game), takes seconds. The menu scraping works so there’s virtually no setup needed.
