Unofficial RetroArch version with Kaillera netplay support.
Based on the original RetroArch version 1.16.0.3 and kaillera netplay code by you_are_doomed.

Version 1.16.0.K0:
- Fixed kaillera netplay input delay. (was +1 frame more than should be, thanks you_are_doomed for fix)
- Fixed input update: in some cases did not work due new input delay fix.
- Rewritten main kaillera code, added support Open Kaillera n02 callbacks also for Linux.
- Rewritten function of adding games to Kaillera list:
now adding with core name, and don't need to restart emulator to add new games to list (only reopen kaillera).
- Now on start kaillera game, core selecting automatically (base on the created game name).
- Fix for window menu bar: now game not freeze while checking menu during kaillera netplay.
- Other minor changes and kaillera code cleanup.


NOTE:
- Not all cores support netplay via kaillera.
- Use the same core versions and core settings to prevent desynch.
- Don't use port remaps, is enough to configure port 1. (may also need configure port 5 for nes games with 4 players)
