View Full Version : Reduce PSX emu CPU speed

March 9th, 2008, 09:21
I've found out that the official PSX emu runs under 333 Mhz but I've heard that it runs fine on 222 Mhz, so how do you change the CPU speed of the PSX emu? You can't just do in in the VHS menu, like you would for XMB and normal games. Is there an option to do that? I have psp slim with 3.80m33

CWCheat (http://dl.qj.net/CWCheat-0.2.1-REV.-A-PSP-Homebrew-Applications/pg/12/fid/15881/catid/151) can change the cpu and bus speeds for any application that is running under it. It seems to work great, but it doesn't save settings for particular games, just a default setting which can cover most apps, but sometimes don't require the power. I use it, and overall, it can be pretty useful.
