Hello everyone!
I have this handheld gaming device that is built with the RK3128. The O.S. is retroarch, however it’s been heavily modified. I want the stock original retroarch installed so I can build on top of that to customize it to my liking.
I noticed that there is a Lakka build that is for the RK3328. Would this work with the RK3128? What should I look out for / change?
Also… while you’re here. Doe’s anyone know if this console is possible to run N64/Dreamcast? CPS3 runs very well. N64 needs optimization after recent tests.
256KB DDR3 Ram is installed.
