hi i got an genesis emulator and i need so good games =).

You need suggestions for good games, or the games themselves?

If you meant the former then all the obvious ones, Sonic 1/2/3, Castlevania, Castle of Illusion, Gunstar Heroes, Golden Axe 1/2/3, Shining Force, Phantasy Star, Streets of Rage 1/2/3, Desert Strike, Thunderforce(s), Herzog Zwei, Fireshark, V-Five.

I tried to stick mostly to exclusives as I find the SNES/Megadrive joint releases are almost always superior on the SNES

castlevania: bloodlines
combat cars
road rash 1, 2, and 3
sonic the hedgehog 2, 3, and sonic & knuckles
streets of rage 2 and 3
teenage mutant ninja turtles: hyperstone heist

There are so much that I cannot list them all.

Tiny Toons ACME All-Stars, I love that game.

Streets of Rage 1/2/3 (preferably 2)
Comix Zone
Sonic 1/2/3
Sonice and Knuckes (fantastic)
Golden Axe 1/2/3

When I name a title, it does include any sequels.

Sonic The Hedgehog
Alien Soldier
Gunstar Heroes
Altered Beast
Toejam & Earl
Golden Axe
Streets of Rage
Shining Force
Mortal Kombat
Ristar
Phantasy Star
Vectorman
Comix Zone
Ecco The Dolphin

Ugh! How could I have forgotten Ecco?? Tides of Time was such a great game!

I could never get past the first coral ocean thing. I've never read a guide to get past it either. The Game Gear version BTW not the genesis one
