This save game feature was planned even previously (in "Mortal Kombat" edition, in fact the same/almost the same one but with different label), both in handheld and "stationary" version, but as I've read in YT comments under reviews, by some reason wasn't implemented into handheld (don't know about stationary version).
I don't understand though why they still didn't included Sonic 3. It was somehow understandable in previous editions without save feature (that they didn't want to include game which had showed you save game from the very beginning of the game, but wouldn't work), but since they've figured out how to pass it in case of pre-loaded Phantasy Star and Sword of Vermilion, couldn't be the same/similar method used for Sonic 3 to add it to available (pre-loaded) titles?
I've never owned "stationary" edition, but handheld is actually not bad. If only there could be solved issue with sound and save games... It would be worth to recommend. It's not an acciddent that almost identical handhelds are sold on AliExpress, but without licences and far cheaper :P
I don't know if it's true, but I've heard that HamyGames (chinese producer) actually developed GenMobile (still selling them, without licences, under different name and set of unlicensed games ;P).
