Just got this bad boy yesterday and I'm like a kid at Christmas! 😄 The delight I felt firing up my old love, Desert Strike... Goosebumps! Seriously impressed with this bit of kit, and I'm enjoying exploring the options as much as the many many games! The effort put in by the community with GarlicOS and the ROM packs is simply magnificent.
I'm so out of the loop, this is blowing my mind. I'm looking at the site @FriendOfFalcons linked (https://anbernic.com/products/rg35xx), wow. Specs look pretty good, this emulator should easily run any PS1, GBA, Neo Geo game. Hahah what, Neo Geo? There's a blast from the past.
I can't find any info on what Linux distro it ships with, does this thing work out of the box or do you have to install the OS? I presume you supply the ROMs? Holy crap, and they have beefier handhelds that support later-gen platforms. This is awesome.
You can play it directly out of the box, but there are custom OS's out there that run things even better and add more features. You do supply the ROMs, but there are plenty of ROM packs out there too to make your life easier. I honestly recommend looking into RetroGameCorps on Youtube, he has some great content around these types of devices.
If you get the RG35XX specifically, I'd recommend this guide.
I’m sorry if this goes against some instance/community rule and if so please just tell me - but where does one find reliable ROM packs? I only ever used EmuParadise back in the day (as I still do - but don’t tell anyone!)
