Congratulations to the developers. 1.3.3 is better again. The EGA
emulation on X is now perfect ("Captain Comic" works 100%).
I have a question about the PC speaker. "emulated" and "native" both
work, and the beeps come out of the PC speaker in both cases. Was it the
case (in the past) that "emulated" meant that simulated beeps came
through the sound card, or has it always been like this? I cannot remember.
Regards, Jan

Emulated vs. native is comparable to graphics in X vs. graphics on the
console. The setting only makes a difference on the console. In X (using
XBell()) or a terminal (^G) the speaker is always emulated.
"Emulated" means that the port I/O that DOS does to generate sound is
trapped and converted into an ioctl (KDMKTONE, see console_ioctl(4)).
"Native" causes the port I/O to be forwarded straight to the hardware.
It needs root but may be more accurate. Well, for simple PACMAN style
beeping games I don't hear any difference, and for advanced PC speaker
"abuse" even native is not enough. YMMV
