My absolute favorite game at the moment is Snes Magical Poppin which was recommended to me by Ninty

Run Saber the Snes version of Strider

Snes X Kaliber hard as it forces you to learn the bosses attack patterns no way can you beat them first attempt like most 360 games

Muysha not very good and impossibly hard with respawning enemies

I know the Snes has a few Eswat clones and a Metal Slug clone
Megadrive Wani Wani World and Twinkle Tales being a personnel favorite's as I have them from the 1990's when I bought them from KT Consoles
Anything obscure also did the Megadrive have any more scrolling fighters other than Golden Axe, Streets of Rage, Sailor Moon and Mystical Fighters
