Quickcheck is the little brother to Statcheck although it operates under the same principles.
Statcheck is quite complicated to set up, not the least because most of the demos in Compet-N are for the copyrighted Doom IWADs which cannot be freely distributed. Instead, Quickcheck makes use of a selected set of fan-made PWAD files and D2ALL long-form demos from the Doomed Speed Demos Archive. These can be run through in a matter of minutes to gain some basic confidence that a source port's behavior is continuing to match Vanilla Doom.
