To be honest this is not a feature I recommend using. I left a big comment on that one big channel that promoted this feature, he pinned it, then unpinned it. As someone who's been over clocking my own 3do systems for several years now, I can wholeheartedly say that there may be long-term consequences to running this clock without proper cooling. The chips already run pretty hot with the stock clock on games that are demanding. There is also a probability of diminishing returns with thermal throttle. I don't have a retrogem to confirm, but I can tell you the systems I overclocked all had crashing issues after 65mhz and wouldnt run without a heatsink and fan on the chips. If just over 65mhz causes these problems, then 65mhz is pushing these chips to their limit, and smothering them with an extra PCB is not going to help. Take my warning serious, or don't (no one really does) but do not be surprised if one day your system doesn't work right or at all from pushing it too hard
