How many percent is up to the emu and how much is up to the plug ins.

Violineb · March 20th, 2003

I was wondering this. How much matters in the emulator and how much in the video/sound plugins. For example if there's an incompatable game I know that both the plugins and emulator can "make or break" it, but how much? For example for PJ 64, other plugins than the default are unnessessary, but of course there's a new vid plugin every time the emulator got up dated..

well, technically, you don't need to have plugins to "emulate" a system...(a debugger would be fine ^^).. but wut fun is it if you can't see or hear anything

It goes something like this, I think.

The emulator passes information to the GPU regarding how the screen is set up - the GPU just draws the polygons.

The psx GPU plugins emulate exactly that little gpu chip inside the psx. Therefore, each gpu plugin is a small hardware emulator as well, and not only a library with some drawing functions.

The same can be said from the SPU plugins (they emulate the psx sound chip), only the CDR ones are more or less 'just' a bunch of functions to access the PC hardware (cd drives).

and for the pad plugins? I mean, what about the multitap? is there a little chip inside? I'm so "stupid", no knowledge at this point :confused:

Thx, bye

What pad plugins do is mostly reading events (from keyboard or joy devices) and update the status of the emulated joypad (button n pressed/released).
I don't think there is much difference in speed between the available plugins; the ability of running mulitthreaded that some plugins provide may make it a bit more responsive, as the events are already collected and processed when the main emu polls the joypad status.
