if your installing mac, it will be slow. the lowest install I've heard of so far is around 2-3 hours. I have a 3.06 HT too...

the mouse speed and fluidness depends on your refresh rate. for installing you want to have the refresh rate high (say 500)...once you have it installed fine, I run at 30 with no problem. if you try 30 when installing osx, prepare for it to take a lot longer.

how do you change the refresh rate? is it the redraw_interval_msec ?


I didn't get what is that value but if I put it lower my mouse moves faster.
what should I put on that value?

higher value -> cpu uses less power drawing and tracking the mouse in pearpc and more to the OS itself (which is why installing is faster if you use a higher redraw/refresh rate). don't use a high redraw rate once osx is installed, there really isn't much of a performance difference

lower value -> cpu uses more power drawing and tracking the mouse in pearpc, the mouse is much smoother...scrolling and other things are smoother too (such as moving windows or navigating the dock). use a lower setting when osx is installed

when your installing, set your redraw rate in the 500 area
when your done installing, set your redraw rate around 40. if your brave, go lower and see how it performs. tweak this number to your liking.

Try Pearpc SDL Windows build.
(see comments in pearpc.net about SDL 3)

It's not very stable and keymap errors in Windows.=_=
But lots of faster than current CVS.

Is the 0.2pre Build from pearpc.net a build for windows?

Or is the code for linux around


I'm installing Mac OS X 10.3 on PearPC 0.1.2 (according to the title bar) and its been going for 9 and a half hours 8O :?

Would the 0.2pre build for linux speed it up? (I can't use a windows version because I'm using the cd (/dev/cdrom) :)

Whats your PC Specs ? If you are having a old PC Specs ? e.g P3 , P2

Then visit this site

http://rudefyet.dyndns.org:6969/ppc.htm

Or if you have Althon XP , P4 or other latest chips

Then visit the Nightly Bulid web site on the FAQ Section

It will speed up the emulation by little...(not that much)

My PC is an XP2600 with 512Mb RAM - high enough spec I should think :?

The nightly builds website only has windows versions and I'm actually running linux


Its now been going for 12 and a half hours and is sitting here now:

Please read http://pearpc.sourceforge.net/getstart. ... ource_luke

You must enable the jitc if you want speed.

I had to compile with the line

./configure --enable-cpu=jitc_x86 && make

The GUI arguement caused the compile to fail :?
It couldnt seem to find a program call NASM? (i think). Never heard of it


Not really noticing any speed increase - still sitting on the grey apple logo after about 5 mins with no disk activity at all :x

How long does it take for you guys, I've waited 15-20mins for the main screen before now :cry:

Make sure you set your compiler flags right for your CPU (P4 en athlon, ...)
And for NASM, its part of cygwin. Run the cygwin setup again, and add nasm to your installation.

I googled NASM and installed that and recompiled and there is a noticable boost :D

I'm a beginner at compiling from source et all. And I just got a crash course, all is well now. Its just I'm a moron :lol:

Thanks - Great program 8)

Strangely enough, using a minimal install (Just the core components), the install took 70 minutes for me. Started at 10:10... Ended at 11:19.
