New LLE RSP Plugin (accurate, fast but untested?)

I know I had been thinking about it, just don't remember posting it.



Excluding some basic HLE of RSP tasks from inside the RSP plugin internally I have no experience with HLE of the RCP, so I have little insight on how to interpret your meaning there.

It should be able to use all the same structures that LLE does, except you are pre-allocating the recompiler for the RSP.
The RSP interpreter plugin will be the simple LLE plugin.
The RSP HLE plugin will "call" the RSP functions as inline macros, sort of, which will pull them into the ucode simulation process and have the compiler "re-compile" all the code statically for you, which is much stronger than writing a dynamic recompiler.

But, I never tried it, just been more fascinated with optimizing LLE.

Hope I partially answered your question somehow.



Not sure I'm following, but if you're asking how to define the LLE interface of the RSP gfx then all of that should be laid out in my RSP plugin already.

It would be useful also to add pre-compilers for the other custom graphics microcodes (Star Wars and such), but I don't find the endeavor of the utmost interest since such ucodes are nonstandard and rarely used. It would be better to worry about the hardware than the software; hence LLE usually does the trick.

Thanks, now I will try to make HLE graphics plugin base on z64gl.

Haha, if you can even get z64gl compiling and building successfully then please let me know, because I have yet to do that.

I got it to build on VS2010 once, but one of the OpenGL inline methods I must have touched (or maybe a bad library) was causing consistent crashes during certain times in-depth into the game.

I have a PM for you.

Another graphics plugin perhaps? Oh, ho, ho! This I gotta see!

Cool! You got it building.

Haven't noticed any speed-ups, but good to know somebody here besides ziggy/angrylion knows how to control this open-source project.

Do you have any OpenGL experience or knowledge?
Maybe you can fix this duplicate pixel rows issue when using low-res native gfx.

Maybe I can help you with it later, since I am pretty much done with the RSP.

Did you test my plugin with HLE? And try to use Zilmer RSP 1.7.0.9 (with recompiler core) at the same time if possible.

Try Star Wars - Rogue Squadron with the settings as picture below:

And a little request for your LLE RSP, can you add a recompiler to it?

Oddly enough, it's about as slow as LLE gfx on Project64 1.6...but the HLE gfx with RSP recompiler seems to play the intro fine.

It can't go in-game though. The original z64gl wasn't capable of that.

I don't really see why I should as of this point in time.

• Not as fast as RCP HLE, which is still slow when using the VR4300 CPU interpreter with some games anyway.
• Also not as fast as static recompilers. If speed was the more significant goal we would be doing those.
• Sacrifices accuracy for speed. An interpreter should be more than enough to perfect emulation by balancing accuracy with speed, whereas a recompiler is too indirect to do the balance as well.
• Makes implementing cycle-accuracy way harder.
• Too much extra data shelled into the program for me to understand, much larger size.
• Most of my improvements to the interpreter can be applied to the speed as well as accuracy of the RSP recompiler; I just have no experience to start out from writing a recompiler. That's what team work is about: Somebody knows how to do the core accuracy, another somebody knows how to do the compiler tricks/speed-ups / N64 plugins.

Yes, you can enter the game, when screen became white (at menu screen), press a,b quickly should bring you into the game.

Odds, I can gain about more 10 fps at my computer with project64 2.1, that make this game playable on my computer.

And make sure to set "Fixed Audio Timing" and "Sync to Audio" off to save cpu loading.

--- Edit ------
The LLE part didn't touch too much, just fixed some locations that cause crash, no speed improvement.

--- Edit ------
Another game you may try is mario tennis, the same way, use my plugin as HLE plugin, and use zimlar's rsp (with recompiler core).

Not yet ready for testing though.
