Overclocking With The Gp2x

[trixom]

Thanks all, forgot the dos 2 unix conversion....

How much of an impact does 40 mhz of clock speed has?
If my gp2x can only go up to 266 - would it be worth to replace it?
Is there still any chance for playble psx games on it?

Well, if you replaced it, you could end up with a lower clocked system too. 40mhz is a useful speed boost. I know the neo geo emulator can be overclocked to 266 to get it running smoothly with sound, so I suggest just appreciating what you have, it's still 66mhz more than it should be

That's true, though I would really like seeing Legends of mana and Castlevania on my machine

GP32z.com indicated that they'd be willing to guarantee a 280MHz GP2X (I asked because I figured friends of mine might fall in love with mine when it arrives from Europe).

However, they take 1 to 2 days to respond to your e-mails, and sometimes need to be e-mailed twice to respond.

Edit: Never heard anyone say anything bad about their end product shipment or returns, however.

We need a tweak like the pencil trick =(

This thread is very helpful, thank you!

Could someone explain what these bolded parameters mean, what changing them does, and why you would change them +/-

The first parameter sets the clock-generator. Choose 0 for FPLL and 1 for UPLL.
The second parameter sets the prescaler for the LCD-timing. Get your prefered values with the graphical-menue. Choose values between
-20 and 36 for FPLL-mode and -5 and 10 for UPLL-mode.
The third parameter sets the CPU-frequency in MHz. Choose a value between 33MHz and 320MHz.
If you use values which are too high or too low, the program exits without changing anything.
The forth parameter sets the gamma-value. You can use values from 0.02 up to 10 where 0.02 is dark and 10 is bright.
