-EmuHawk does have some prerequisites which it can't work without (it will let you know if they're missing). The list is [here](https://github.com/TASEmulators/BizHawk-Prereqs/blob/master/README), and we've made an all-in-one installer which you can get [here](https://github.com/TASEmulators/BizHawk-Prereqs/releases/latest).
