set your dosbox to 2500 cycles
then run the game

just tried that, makes no difference at all 🙁

run install and choose sound blaster

tried soundblaster, adlin, roland, kevin....all to no avail. i assume it works fine for you? or are you guessing?

Try running in 0.60, flashback seems to be a bit picky oabout screen update timing and that doesn't seem to be exactly the way it wants in 0.61

aha! known problem then, no worries, thanks!

hm. strange cause it works exactly the same way in both 0.60 and 0.61 for me:

adlib+6000cycles->ok
adlib+2500->too slow

sb+6000->a bit slow
sb+2500->ok

*adlib (it doesn't matter whether you choose fast or slow machine in install.exe, they both works the same way)

Is a kinda slow at 2500. 2600 is a better value to use with SB sound fx....
you can compare the intro music speed with SNES version.... 2600 is much better.......

very strange: i use boxer frontend and i put an autoexecute commands to all games....... at 2500 + autoexecute is very very slow.... at 2600 + autoexecute is normal.... 2500 + typing manually all these commands is only a little slow.......
very.... very strange.

i use these commands at autoexecute:
mount c c:\old\fback
c:
fb
exit

more strange things: you can use a value higher than 3000, but you must set SB for sfx and adlib for music..... with MT32 you get a slow game.....
to use MT32 for music and SB for sfx you must use a value between 2600~2900

this game appears to be speed sensitive...............

i'm using boxer FE 0.61.5 and dosbox 0.61

See my reply in this thread:

Slow running games ...

Erm, tcm1998, although your reply in the more recent thread is appreciated, there's little point in necro-ing a thread that's more than a year old just to point it out.

Hmm, I didn't look at the date. Sorry 😊

Funny how people get chided both for not searching before posting and for posting in an old thread that was found by searching...
