I looked at this a few times in last year or two https://www.amazon.co.uk/Retro-Super-Console-Version-Electronic/dp/B00Q2MCSIC But no SMS cart slot, is a sin really. The reviews suggest the funstock retro is a bit cheaply made, and unreliable for cart reading, as someone has already mentioned... https://www.amazon.co.uk/Retro-Freak-12-1-Games-Console/product-reviews/B01LWIMCJD/ref=cm_cr_dp_d_show_all_btm?ie=UTF8&reviewerType=all_reviews The funstock retro might do more, but I'd rather go for the Retro-Bit 3-in1 myself as is a better build, dedicated cart slots, and that it has the original pin ports, you can use the original SMD/NES/SNES control pads with it.
Have had one of these for a while, emulation seems fine, and once you've copied games to it you can take the small pi sized part to friends' houses, so very portable. Found that mega drive game compatibility seemed pretty poor (didn't seem to work with PAL EA titles?), but everything else has been fine so far. It's not particularly suitable to load up with 100s of ROMS, as the interface gets super slow if you do. I like the controller adapter, using the original controllers feels nicer than using some of the modern USB versions.
This is best on Sony consoles, don't play it on no name brands like Sega.
I'd buy such a thing :) A dreamcast mini... although I guess if it supported original games it wouldn't be that mini, would be an instant buy for me.
Good argument, you can buy converters I guess. The emulation games werent designed for HD anyway, so if you use Scart, you're not losing much. I think modern tv's still cater for scart? (not too certain - been about 5 yrs since I bought one).
