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":

[snip]
Illegal read from ffffffcc, CS:IP 160: f69a
Illegal 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.

Thanks for your assistance. I've edited the OP as I forgot to mention the various mem settings that I've tried also without success. I do confirm the crash will occur on SVN as well. I need to test with ECE and X indeed. For the record the "eXo" version does rely on ECE (not sure it's fine to mention this on that forum if not let me know).
