Description

I can speed up multiple instances of retroarch gpsp when playing pokemon firered by pressing the right trigger button on the emulated xbox 360 controller with key2joy. I'm using background input. When i assign the left trigger button (for example, axis +4 or the left trigger button) to slow down (toggle) it doesn't slow down during lan netplay multiplayer (gba wireless adapter on gpsp). Also, it both instances have the same slow down ratio.

Research direction

Start by reproducing the slowdown-toggle behavior with two RetroArch gpsp instances, background input, and LAN netplay using the GBA wireless adapter. Compare local slowdown with netplay behavior and check whether both instances receive the same slowdown ratio; done means the left-trigger slowdown toggle works correctly during multiplayer.
