NullDC-NAOMI Netplay Launcher Wiki

FOID (Frame Over Input Delay)

This launcher is based off the technique uncovered by supersonicstep on the FGC Arcadia Discord. The way netplay works is by using an emulator that can run at a high framerate uncapped (in nullDC's case, ~300fps), and running an external frame limiter on top of it to operate at 60fps.

qkoJAMMA

Paired with the nullDC qkoJAMMA plugin, uncovered from the dustloop forums 10 years ago, supersonicstep managed to get very playable netplay working with this method. The best resource for qkoJAMMA information itself seems to be this abandoned GuiltyGear XX AC Online. The plugin itself had to be excavated from an old hard drive.
