Just another Retro Handheld deal.
The Trimui Smart Pro plays up to PS1 and could be seen as a competitor to the current X55 deal.
The 4.9" screen is really nice especially for GBA and PSP.
The stock firmware isn't too bad for basic use and there's a number of CFW options under development primarily Tomato OS (more an addon than a custom firmware) and Knulli (first public alpha). I'm used to ArkOS on my RGB30 but the stock on this unit does its job for me to just play games and do a few tweaks. Will probably go Knulli once it's a bit more mature.
Primarily use this at home and it just sits next to my WFH setup for when I need a quick break :)
