Hi, my first post here. I'll do my best to provide any details allowing a resolution.

Issue:
Theme Park (CD) is crashing after a while on 0.74-2, 0.74-3 and SVN.

Log "trace":

1[snip]
2Illegal read from ffffffcc, CS:IP      160:    f69a
3Illegal write to ffffffcc, CS:IP      160:    f69a

Potential fixes I've tried thus far without success:

* core = normal, simple or dynamic
* cputype = 486_slow
* cycles = auto or fixed
* General MIDI/MT-32 or SB16 "FM"
* SBPRO1/2
* various mem settings (ems true/false, xms true/false, combination of the 2 etc)
* multiple CD versions (US/Europe)
* VGA only and SVGA (press 'R' while in-game)
* copy all files over the hard drive
* to replace game's extender with DOS/32A.

Last but not least I gave the GoG "version" a try which comes with a slightly modified 0.74-2. This version does work fine for couple of hours or so yet it will eventually end up crashing too. It just takes longer than with 0.74-3. Note the crash screen is the same as above:

Steps to reproduce:
- simply run the game (whichever version), enter a name then start a normal game.
- once in the park, just let the game run without touching anything (crash is not related to a specific screen or action in-game).
- depending on your DOSBox version the game will crash after few minutes (typically under 10mn with 0.74-3 and SVN) or typically after 30mn (with 0.74-2).

Extra notes:
- tested on standard Win10 x64 and also on Raspberry Pi4.
- as far as my memory goes I never had such issue with that game back in the old days. I'm running out of idea to get this game playable hence any help appreciated.

Thanks in advance.
