More granular TWL clock control to allieviate problems with DS games running at faster CPU speed?

[jan-kleks]

Could it be that with the speeds lower than 133 MHz (but still faster than the original DS clock to reduce slowdowns) some games would work better? And if there is no way to control the MHz directly, maybe something could run together with the game, slowing down the CPU (a bit as in the DOS days: https://www.vogons.org/viewtopic.php?t=44)?
