You can follow the general setup guide at https://crowdcontrol.live/setup for extra help with the Twitch Extension, the Crowd Control Desktop Client and other options.
We suggest using the One Click Setup to install Bizhawk, which is found in the Crowd Control Desktop Client. Bizhawk 2.8 is required.
We support the USA Version of Tony Hawk Pro Skater 2 for the Playstation 1. Just point the Crowd Control app at your disk image(.cue, .iso, etc).
In order to use PSX with Bizhawk, you will also need to obtain a copy of the USA PSX BIOS, SCPH7001.BIN. We will not be able to provide the BIOS.
