I got the grey running Amberelec and it’s very nice but I did upgrade to a retroid pocket 3+ but kinda separated the two with the RG being a 8/16 bit powerhouse and the RP3 being a PSP/NDS focus with some widescreen hacks (bsnes hd) on the side.
The RG351v would be used more if it had 5Ghz wifi, and my router can’t do both. Retroachievements are too nice.
