Was considering it but the fact that it has an inferior chip with lower performance and is still chunkier than the RP3+ is kind of a turnoff. If I buy a new retroid device I expect at least a performance increase.
Btw don’t be satisfied with black bars, I’ve been using game specific art bezels from thebezelproject on my RP3+ and widescreen hacks when available. Those 4:3 games look gorgeous on that RP3+ screen.
