Decided to try Doomsday out for the first time today. I own Heretic: Shadow of the Serpent Riders on Steam (as well as the Hexens). I have a problem getting Heretic to work correctly with the jHRP unfortunately.
Everything works fine, except the weapons. Some of them are barely visible at the bottom of the screen (elven rod, firemace, and gauntlets). A couple appear at the far left side (Phoenix Rod and Hellstaff). The melee staff is stuck on the far right side and the other two weapons (Ethereal Crossbow and Dragon Claw) are completely invisible (they still fire though).
I've tried running this in full screen (1920x1080, my monitors native rez) and in various windowed resolutions. I also tried changing the field of view, didn't help. What'd I do wrong?
