request SMS Sonic The Hedgehog series level select

[eadmaster]

Sonic The Hedgehog 2 and Sonic Chaos have a builtin Level Select menu.
It would be nice enabling it without pressing key combinations.

Sonic The Hedgehog 1 doesn't have such a menu,
btw a levelskip button would be nice too!

Other Sonic games with a builtin level select menu and still missing a code are:

Sonic Chaos (Game Gear version)
Sonic Pocket Adventure (Neo Geo Pocket)
Sonic 3D Blast (Genesis version) - already done, but can't be statically patched in the ROM (infinite loop)

Can someone make a code for Sonic the Hedgehog 2 (SMS) for the chaos emeralds? I read that the ending is determined by whether you have collected them all or not, but I'd like to see if there are different endings depending on how many you collected.

Also, there are 2 different versions of this game. Does anyone know if there is a noticeable difference in them?
