Consensual typically shows a message to explain why. Either you're trying to run it on an old version of Stepmania, or you're trying to run it with the d3d renderer.
If you want to try it with the d3d renderer, disable this check
, take some screenshots, and compare them to mine
. I got some reports that things looked really weird with d3d, so I stuck it in the version check.
Before I start explaining the metrics, I should say that I haven't used them to do useful work in over a year. They can't be dynamically generated or modified in many cases, so building a generalized system off of them tends to be a copy paste pain.
So you see something like this in the metrics:
EffectsReceptorDefault="mod,no confusion,no invert,no flip,no mini,no xmode"
That creates an option row with 6 choices and allows the player to select multiple choices on the row.
Each option is one GameCommand. In this case, each one is setting the name field of the GameCommand, which will be displayed, and the mod field, which will be applied to the player. There's a whole load of mods listed in PlayerOptions.cpp. You can see how to change -35% to the percentage you want.
