Not anytime soon
The core emulation routines are hand coded in assembly. The JITC core is a thing beauty (and mystery to me). I (and many others) have brought up the possibilty of using the AMD64 ISA via linux (Windows 64 will not be out until mid 2005 at the earliest) to gain the benefits of the extra registers (th...

HT does not dual CPUs
Please remember that hyperthreading basically just splits up the cacheline (to more efficiently feed the execution units). I do not know how cache heavy PPC is, but most emulators are very stressing to the cacheline. Also, PPC is not HT aware and could render strange results. But please, keep us pos...

Considering that PPC currently is using SDL and SDL uses DirectX in windows, I do not see DOS handing that. There are a lot of other reasons, but suffice it to say that what is going to make PPC faster is tuning in a couple of key areas. MMU and FPU functions are the targeted areas right now as they...

CVS = concurrent versioning system This is the live code being worked on as we speak. Stored as source code. SDL = simple directmedia library A multimedia runtime layer (like DirectX except cross platform). It was added later on to the pre .3 version branch as the new graphics layer. Earlier builds ...

SDL custom blitter examples
Found some proggies showing how to make a fast HW blitter that uses SDL and OpenGL. http://olofson.net/examples.html There are other examples all over his site. Also, found out that all windows in OS X are double buffered and SDL apparantly deals with this MUCH better when using HW surfaces (fullscr...

Changes made in build
Looks like our favorite devs have been busy. Looking through the changes to the CVS, looks like the stuttering mouse has a hack in place to fix and four more instructions emulated in the ALU.
I am too tired build. Somebody check it out tomorrow (today?).

Compile by hand
Looking through the source for the video driver (video.x), it appears the resolutions available are hard coded in the build. You should be able to add a { 1280, 800 } or whatever in the build. I am more interested in the odd "dots" that appear to be from the video driver converting 24 bit ...

I just share a folder on the PC side and mount it on the OS X side and run dmg files directly from the shared drive. Actually, I run a lot of software from the share.

OpenGL is for professional work
OpenGL prtty much dominates the professional market (CAD, broadcasting, movies, etc.), but has fallen out of favor with the MS because, well, DirectX is easier to program for. The equivalent to directx on the (old) mac would be Quicktime (it is a multimedia layer also with sound, network, IO, video,...
