Dreamcast handheld suggestions

Trying to find the right fit, but seemingly finding fault with everything i see. I really like the look of the 406v to set up as a dreamcast specific handheld, but i dont want another android os system. The cubexx has that similar look, but ive heard dc emulation is hit and miss. Im also worried it’ll feel cheap; id prefer to pay more for a good device if one exists. Is there anything else without wide screen and a linux os that has that curved body feel and can play dreamcast flawlessly? Would also prefer all white housing to feel authentic.
