Both the PowKiddy RGB30 and PowKiddy X55 share the same $90 price, RockChip RK3566 chip, JELOS-based Linux software, and an emulation ceiling around PSP, so the choice comes down to physical design. The RGB30 launched in September 2023 with a square-ish screen favored for Game Boy Advance and other 1:1-ratio systems, while the X55, released four months earlier, uses a larger widescreen display that suits systems with 16:9 output.
