Want to play System 11 games faster with sound enabled? Try this replacement s11player.dll. It replaces the HLE engine with real sound emulation similar to what will be built into ZiNc 1.2, and it should be faster (and better sounding, especially in stereo!) than current. It's not been heavily tested here and may be buggy itself, so save a copy of your original s11player.dll first.

Anyway, if you see a difference in framerate (positive or negative), please give your CPU speed , the game you were trying, and approximate "before" and "after" framerates.

As a reminder, System 11 games are:
Star Sweep
Kosodate Quiz My Angel 3
Tekken
Tekken 2
Soul Edge
Dunk Mania
Prime Goal EX

Other games will show no change with this new file.

WARNING: In order for the new player to operate, you need a copy of the ROM file "pr1data.8k". This is contained in the current MAME sets for all of the System 11 games, and you should unzip it and place it in the root of your C:\ drive. This is a temporary workaround because I couldn't change the application - ZiNc 1.2 will not do anything this gross :-) If ZiNc crashes on startup with the new dll, this is likely your problem.
