No warranties, use at your own risk, and so on. WARNING: It is not compatible with Atari Flashback 9 - DO NOT apply it to those units, as it will permanently BREAK them. You have been warned. This works in conjunction with the Nexus 5.1 (or later) release from Draxxon to enable these: When in the menu, the device will operate at 816Mhz (the original Atari Flashback X factory clock rate). Playing Atari 2600, the device will operate at 1008Mhz (factory clock rate of Atari Flashback 9). Playing other games, the device will operate at 1200Mhz (the overclock rate we have been using up 'til now - matches the Legends Flashback units). How does this work (what I'm really asking - via what mechanism is the speed altered)? I know there was an operating theory that you could modify a proc filesystem attribute to dynamically adjust the maximum clock, but I don't see anywhere in NEXUS that's done. I unpacked your firmware and don't see it either...what am I missing? (What I'm really after: Dynamic clocking of *just* 2600 titles, based on CRC32 or md5sum lookup table...default clock of 1200, downthrottled to 816 for problem titles like Asteroids.)
