How do you play ZanZan on GZDoom?

[Barry]

I have downloaded this wad "ZANZAN TC Pack". You are mainly supposed to play it in ZDoom, but I want to play it in GZDoom. If there is
not an answer to play it in GZDoom, will someone please tell how you play it in ZDoom, because when I do that, everything works, but the
screen is windowed in some kind of a way, and I can't get it right to make it full screen. The wad can be downloaded from this website:

There's a newer version on /idgames. This old version was made for a long obsolete version of ZDoomGL that never worked properly.

I downloaded the GZDoom version, and it seems like it is working. Thank you very much Mr. Oelckers!
