Playing with the shareware 1.9 IWAD does not display the third episode's title for some reason on the episode selection screen.

I'll check into this, there are more bugs out there for sure.

Is Doom faster when it uses a chained hash table instead of linear search?

I haven't implemented it yet, but I think this should be a minor speedup, as the number of visplanes used ingame aren't that much (original WADs).

I confirm that on the laptop 486 DX2 50Mhz fps increased by 1.52 (from 17.62 to 19.20) using Dos Benchmark Pack config for faster PC.

Can you post your laptop specs? I'm analyzing which are the major bottlenecks in Doom depending of the hardware, so i can focus in those bottlenecks.

I'm assuming NukeYKT reverse-engineered their own DMX-like given their prior work on the Doom OPL3 Windows MIDI driver.

This port is using NukeYKT sound library from PCDoom-v2, i don't know if it's the original version, a reverse-engineered one or custom made. My idea it's to replace it complitely to a custom one, so the sound cache problems can be fixed and make the tickrate control internal instead of depending in the sound library.
