Well...
That does not matter.
As soon as the game enters player mode it CRASHES!
DOSBox just shuts down with no messages.

Guess I'll see if I can get the Playstation Emulator going...

Hmmm...
I have DOS 6.22 & FreeDOS in VirtualBox, that might work.
VirtualBox - not much good for gaming.
FreeDOS...

I want DOSBox to work!

Start the game like this: F2B -2

The -2 parameter avoids the CD speed check. However, I've not had any problem with the game crashing using default settings. Not sure what's in your FTB batch file, but try typing all commands manually when troubleshooting.

my ftb.bat

1@ echo off
2imgmount d "/home/caltrop/ISO/DOS/Fade to Black.iso" -t cdrom -fs iso
3cd \games\f2b
4call f2b
5cd \
6imgmount -u d

f2b is what was installed
could have a bad ISO...?
everything is fine until the game actually starts
the chunky first person character appears then DOSBox shuts down

my modified batch file

1@ echo off
2imgmount d "/home/caltrop/ISO/DOS/Fade to Black.iso" -t cdrom
3cd \games\f2b
4call f2b -2
5cd \
6imgmount -u d

that ftb -2 causes immediate DOSBox CRASH!

FYI: sound is backwards
probably the HDMI output

I use the audio output from the external monitor
one less cable to plug into the computer

MY GOD! but it is always something
so far my experience with DOSBox is less than satisfactory
for that matter my overall gaming experience with Linux SUCKS! 🙁

how come the 🙁 (sad) emoticon is not in the list...

here's how to reverse the sound

1pactl load-module module-remap-sink sink_name=reverse-stereo master=0 channels=2 master_channel_map=front-right,front-left channel_map=front-left,front-right
2pactl set-default-sink reverse-stereo

I put that in a startup script I have to fix various things when Linux Mint Mate starts

or you can edit /etc/pulse/default.pa

OH MY...
that kinda mess up the audio system
the volume control gets messed up
pulse-audio is problematic in Linux

fun, Fun, FUN in the land of computers... 😮

Try a build of 0.74-2, as there have been some dynrec improvements that may help with the apparent stability problems you're having with F2B.
