Well, I´ ve talked to the author of GLquake Massimiliano Tretene
and he isn´t developing glquake for Amiga
anymore due to short time.
The last official version was the 0.6b. He sent
me a 0.7b because I had problems with displaying
it correctly on my Voodoo3/4 GFX cards.
It didn´t solve the problem ;o(
