Original Sonic the Hedgehog (the 1991 Mega Drive version) is a fun game, but it does have some significant design problems by modern standards. For me, a person with very mediocre platforming skills, a probably the biggest problem is the complete lack of any kind of save/password systems, while both the extra lives and the continues are quite rare power-ups I am not able to find often enough. As a result, I run into the Game Over screen pretty quickly, and the game itself isn't that much fun because of the challenge.
My question is - is there any version of the original Sonic the Hedgehog that features unlimited continues, flexible save/load system or level passwords feature? I know none of them are present in the original, but since the game appeared numerous times in various compilations and digital services for a range of platforms, maybe some of them possessed some newbie-friendly features?
