thats impact an emulator for the zn-1 and zn-2 games it was not devloped very much, it had sound errors (think here zangief going weee in a very girly squeeky voice while he does his pile-driver) but it ran fast. the impact team stopped working on the emulator. i think this was because someone released a beta without thier knowdlege, not sure on that.
so pimp where are you comparing these emulators? perhaps your hinting things or wish to start a pointless flame war or something, please explain if you can or someone just close the thread.
