Namco Medal Games - Happy Planet, Galaxian Fever, Shooting Paradise, all now fully playable in MAME

I played around a bit and got all these Namco medal games fully playable. They are ok games but get boring quickly. The real machine is probably a bit better but it also gets boring after a while. Anyway, these are working in my local MAME compile now :-D The emulation is pretty good but the sensors are very, erm, sensitive, so sometimes the game shows an error about the gun or sensors if the hit sensors are triggered for too long or if the gun trigger is held down for too long. The first two games just auto fix the error and continue quickly when the controls are released but the last game (in this vid) requires pressing a button on the control panel to continue. That is because Shooting Paradise is the first game on this Namco SG-VGA System PCB and the game programming is a bit rough around the edges. The later games were modified so the errors show less often or not at all. There's also a few very subtle variations in the way the sensors are hooked up between all 3 games, it's not one hookup for everything. Note these games have no end. On the real machine you play until you run out of medals or get bored. In MAME the gun is always loaded with medals so you can play forever if you want ;-) If you stop playing, after a short wait the game shows the title screen. ... that's normal.
