Hacking MKWII Riivolution custom tracks don't work in multiplayer

[Edmonds]

I've recently gotten into common.szs modding, but to do that required me to use Riivolution instead of CTGP mystuff folder. I was trying to put some premade custom tracks onto Rii to play with the boys, but it only works in singleplayer.
I'm new to Rii, not new to MKWII modding, does anyone know what the issue is? The file is just names factory_course, but it's a U8/SZS archive already. Does it need to be named factory_course.szs?

Help!

Multiplayer courses need _d appended to the filename iirc, so factory_course.szs (if you have file extensions enabled) would become factory_course_d.szs

Oh sweet, thanks! Glad to hear it's a very easy fix.
