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...

Yeah, the easiest way is to just share a folde ron the host. You can connect to it in OS X and save the shortcut to the dock. It makes it real easy to move between the two.

Replies: 12

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...

Switch your drives around and switch prom_bootmethod = "select" to "auto"

From benchmarks that are able to run within OS X on PPC, it appears that the IDE performance is better than a real Mac.

I have noticed some changes in the CVS to better the IDE flush operations but I have absolutely no idea what this will mean for the emu.

Can't believe I missed that, too. I looked right at it and didn't even notice it.

Grezly is right, that should do it. BTW, I am assuming you have the OS X install CD in your drive, right? (I am on windows, so I have to have an ISO loaded at all times or PPC freaks).

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...

This means a smaller model for emulation as (hopefully) as much of the bare metal can be exposed as is possible. I do not know how this will work with SDL, though, as I thought it was abstracting. Doesn't that kinda conflict or am I way off base? Beyond my skills.

The jittery mouse thing is in the official builds (just not .2...heh).

Looks like seppel put in some mitigating code to fix that specific problem last night. I haven't tried it yet, though.

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 ...

Just turn the NIC off and then on again in OS X. Comes back pretty quick for me. Networking can be a tad flaky right now, so be patient. Also, I am using a non-standard windows build so YMMV.

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,...
