50g - overclock

[TravisE]

Vtile: Make sure the program “launcher.bin” included with those tools is in the same directory when you run those programs. Your stack output suggests it's not being found.

I've played with these tools on the 50g and found that they sort of work, but not very well.

Underclocking is okay (though SLON is a bit wonky and doesn't always seem to work properly), but if I try to use anything higher than about 90–100 MHz, my calculators actually start running slower, not faster. Also, changing the clock speed seems to make TICKS behave in a very jittery way (even worse than normal operation, where it occasionally glitches already).

On one of my 50g, the highest clock speeds “work”, but don't really run significantly faster. On the other 50g unit I have, they lock up the system altogether and I have to remove power to force a reboot.

From what I've heard (and according to the thread Helix linked to), HPGCC(3?) handles this much better, but I'm not familiar with it and have never delved into it. Has anyone ever considered using it to create modern wrappers allowing users to change the CPU speed on the 50g properly? Is that actually doable?
