It is very simple to overclock your explorer
Preliminary Overclock
Lets say you want to boost the speed up to 532.5mhz?
echo 532500000 > /usr/speed
to speed up your system it is as easy as typing the following
cat /usr/speed > /sys/devices/platform/lf1000-gpio/cpu_freq_in_hz
enjoy
Living Dangerously
Once you have tested your overclock, and are sure that it is stable, and you haven't made any typos... You can actually get the startup script to automagically set the cpu freq for you!
There is a line in /etc/init.d/rcS that checks for /flags/cpu_freq_in_hz, and automatically copies the contents to /sys/devices/platform/lf1000-gpio/cpu_freq_in_hz!
It is important that you test your chosen cpu frequency first using the procedure in section 1, or you might be left with an unbootable device.
echo 532500000 > /usr/cpu_freq_in_hz
Now just reboot, and your Leapster Explorer will automatically boot at the faster speed. Again, this is dangerous, so test it first with the above method. I cannot stress this enough.
