There surely should be the possibility to compile against both library versions.

SDL 1.3 will have some nasty surprises btw. like http://lists.libsdl.org/pipermail/sdl-libsdl. … ber/071878.html which sort of disqualifies the Simple DirectMedia Layer as Media layer but just an audio/video interface at best.

Ok, I hadn't thought about multi-threaded code running in the host... Well that shouldn't matter if you're using some C-library or whatever, and even SSEx should be fine in asm blocks. But for the emulation part you'll have to define a unified register set, as afaik the registers are shared between …

SSE2 is a strict superset of MMX, but it uses different registers (xmm, which are 128bit wide although they can be used for MMX-like 64bit code as well), so I don't think it will interact with the FPU emulation On the host-side, yes (emulating the mmx instructions in sse(2)). On the emulation side, …

I think that there should be a version of dosbox specifically made for running old business/scientific/industrial applications. No there shouldn't.

And please post the contents of regs.h as seen in visual studio (includes directory).

P.S. I expect this to be slow... Me too :) But forget about the normal core as it uses the host fpu so mmx would get a mess for sure. Both recompilers use the normal core for unhandled opcodes, see core_dynrec.cpp: case BR_Opcode: // some instruction has been encountered that could not be …

I've only followed 1.2.x development, yet there are some messages where they preferred to not break 1.2.x api compatibility when discussing some 1.3 stuff. Still might be a lot work to switch, dunno.
Re: Wish for SDL 1.3 support

Oh i feel the need to reply ;) Sadly the SDL people switched to 1.3 development (which still is in beta stage yet said to be "quite far"), leaving 1.2.x more or less as-is which still is not in a too nice state. Anybody got some experience with api compatibility (how to port)? As there should be co- …
Re: Got gcov to work in msys.

Given the amount of code bloat the inlining introduces, i'd suppose it's faster with the call than having the cache filled up with same code blocks.

Posted on 2009-09-10, 12:05
How exactly are you compiling it? As it works fine with visual studio 2008 pro out of the box. And please post the contents of regs.h as seen in visual studio (includes directory).

Wouldn't turning of memory function inlining of the normal core have the same effect, which i recommended some time ago?

What actual problem DO you have with 0.73 and dos4gw for a regular installation of this game??
Re: Pentium MMX emulation - possible?
Posted on 2009-09-09, 08:33
There's no sarcasm, and while i don't see any reason for MMX emulation i'm curious how far you'll get. Especially when using host-wise SSEx stuff.

A few of the dozens of guides to run the game, which also recommended to use the normal setting of the game, didn't worked a quarter as good as the one in the first post. Fine. Use what works for you. And what about the speed? I don't care about that because it's useless to compare speeds if dos4gw …

Re: Pentium MMX emulation - possible?
Posted on 2009-09-08, 09:11
Nothing for what i'd implement a complex additional instruction set into the emulation, especially not for the "for performance reasons" argument, so good luck.

Along with the 0.73 dosbox release i'd recommend the dos4gw that ships with the game, or the 2.01 one, they usually provide the best compatibility.

This game works only under Win95/98 and need MMX. What message do you get?
