Questions about various things (mostly TNCQ G2)

[Danfun64]

Been awhile since I posted here I think. It looks like a large amount of threads with old download links have disappeared since I was here least.

Anyway, TNCQ G2. It's still available on the Chex Quest Gallery, alongside the weird questionably legal version of Doom 2 it was built on.

First of all, I believe it required OpenGL to work? I don't remember now, and it's hard to find information on it.

Second, it's very difficult to get past the first area in gzdoom. The weird tight section where you have to go diagnally, it doesn't seem to work (it does in Zandronum though). Are there any compatibility settings I'm missing?
