time to download srb2kart!!!
first of all, get the vanilla game from this link.
note about the "installer" - it's just a winrar self-extracting thing. also note that this doesn't create a folder - create one yourself and point it here!!!
after getting vanilla game, download srb2kart galaxy from this link. this is a zip file.
then, just extract the .exe to your game folder, replace the stock srb2kart.exe with it.
and you're done! launch the game (please do so in OpenGL mode using the included batch scripts, don't bother with default software mode) and connect to kart.szprink.xyz to race your fellow gaslighters!!!
have fun!!!
