if you were the proud owner of an A500, (or any other amiga) you were probably as much a fan of Rick Dangerous as i was, anyway, i found a flash version on the web, and simply extracted the flash file using activity window, now i play it whenever i like ( a lot at the mo lol) only problem is there doesnt seem to be a Rick Dangerous 2 out there in flash form
