Dual Core Netplay

[kidkilla]

Can someone explain to me why certain games cannot use dual core on Netplay? Thanks for the help!

From https://dolphin-emu.org/docs/guides/netplay-guide/
Deterministic Dualcore Netplay is now merged into master. While compatibility is not perfect, it should allow more games to synchronize on dualcore with three exceptions. Games that require Skip EFB Access to CPU, Store EFB Copies to Texture Only and/or Disable XFB unchecked in the Graphics > Hacks settings are not guaranteed to sync up. There are exceptions to this, but single core is recommended in games that require those settings. As well, some games are not compatible with deterministic dualcore netplay and will hang. Disabling Dualcore will provide better compatibility but lower performance.

Fixing these would probably lower speeds to single core anyway.
