I've just reinstalled Theme Park on my Mac. After the little introduction video, I get a bunch of "File error" messages. After the last one, DOSbox exits.

I've tried this was "no sound" and with SB sound options selected. Regardless of my choice in Setup, I get music during the intro.

Any ideas?

With GOG Galaxy, select "MORE" -> "Manage Installation" -> "verify".

After that, select again "MORE" -> "Other" and than "Launch Settings"

Soud: Soundlaster 16 ASP
Music General Midi
IRQ: 7
DMA: 1
SOUND IO: 220
MUSIC IO: 330

Select: SAVE SOUND & LANG. CONFIG. ONLY !!!!!

Then: Exit to DOS
