Random thought as I find myself returning to this thread, looking over at great 14'ish inch CRT I just finished tuning to peak performance, also musing about whether I want to put it into a cabinet just for this game. Has been a while since I last played it with the factory controls. Seems I really do miss this experience. Maybe Ground Kontrol here locally has a Defender... But I digress, and really want to pose a tech question: How robust are the parts of the game managing resources? Has anyone dropped a 6309 into their game, or run their CPU at a higher clock? Secondly, have people made modifications, such as something like a lander from hell wave, where they just keep coming, or maybe all pods, that kind of thing?
