Another Contra fan here Going through that freakin game over and over,completed it like 98 times or sometn,cant remmember I was renting out cartridges from the video store,so I played really alot of games on the old NES.I remmember atm Marios,and the sequels,Punch out,Chip and dale,Darkwing duck and many many more.

mmm do u know MAME (Multiple Arcade Machine Emulator) ? this program emulate lot of game machines omg i have thousand well known games i.e. don key kong, mario, kung fu master...and all game what u said here.

MAME emulate purely hardware, game-files are original files from that machines. So for playing u need insert coins and u can use joystick or what u want, just u must know how

my tip for u: use F5 for insert coins and send me these free money
