The bottomline is that IDK why it doesn't work on dosbox-x but I took the latest dosbox-x and ran gwtutor.exe (using a google search for archive and Game Wizard 32 Pro 3.0) and it crashed dosbox-x with the following msg:
[...]
LOG: Flush STDIN
LOG: Flush STDIN
LOG: Flush STDIN
LOG: DOSBox-X has switched to max cycles, because of the setting: cycles=auto.
If the game runs too fast, try a fixed cycles amount in DOSBox-X's options.
LOG: Restart by keyboard controller requested
LOG: CMOS Shutdown byte 0x0a says to jump to reset vector 0b9f:05d6
LOG: E_Exit: Sorry, CMOS shutdown CPU reset method is not compatible with dynamic core
E_Exit: Sorry, CMOS shutdown CPU reset method is not compatible with dynamic core
Maybe that's why, let me know what I can try, IDK what is a dynamic core TBH.
