For those who can't wait for La Machine Guns to be emulated properly, it is Emulated pretty well on the dolphin Emulator and Playable, it was included with Gunblade NY in the WII Arcade hits pack.
I brought the game but you need a certain drive to extract the ISO so i downloaded a ISO that was 1GB and unpacked to 4GB, not aloud to post a link sorry. Everything is controlled with the mouse with that game.
I also included scud race running on Super Model, it appears to be running at full speed, my video card is a N'vidia GT240, and my CPU is a Intel core 2 duo, 3.16ghz each, and 2.75GB of RAM.
