Just more of a Steam Deck Light with a smaller 5.5" screen! Remember the YouTube video is someone else's build. I also want to push it further with a hardware upgrade in the future.
I already play several Steam games on it natively- including Portal 1 and 2 which run great. Some are slow to launch but most 2D games and many older 3D games are running on it. Using Gamescope you can reduce the resolution and have it mimic fullscreen mode for better performance than sticking with the full 1080p of this little screen.
I haven't yet tried a PS1 emulator, but PS1 games should be able to run very well here. I've already used PPSSPP and ReDream which run their respective PSP and Dreamcast games fine. It starts to hit a performance wall with GameCube emulation. The Dolphin emulator unfortunately performs worse on Linux than on Windows (using the Vulkan backend).
From here there are three options I could upgrade to:
LattePanda Alpha with m3-8100y - intel iGPU has 24CUs compared to the Delta's 12CU and about twice as expensive
Compute Stick with m3-6Y30 processor - same iGPU as the Alpha but much cheaper and less workable I/O (I would need a USB hub/splitter)
DFI GHF51 with Ryzen R1305G - costs as much as the Alpha, and I/O needs to be added, but has a Vega 3 iGPU, so it should be the best iGPU of all three.
The Compute Stick and DFI board would require expanding storage much like the Steam Deck, by using SD cards only.
