Illegal instruction while trying to run HoMM3 Complete Demo

[ghost]

Steps to reproduce:

1. Get a working OS9.
2. Download https://archive.org/download/heroes_3_complete_demo/heroes_3_complete_demo.sit
3. Install.
4. Run.
5. Click either "new game" or "quit". It will get the same result.

SheepShaver hangs with the following message spamming the logs:

Illegal instruction at 5046d304, opcode = 0f040000

This is happening in SheepShaver 2.5 from Korkman/macemu-appimage-builder@1f0b700

Good news @kerneliusz . I found the issue is caused by using the "wrong" ROM for OS9. This one works:

1999 PowerPC (New World 1.6) [8.6].rom
md5: be65e1c4f04a3f2881d6e8de47d66454

[ghost]

I'm unable to repeat the tests due to another obstacle: #270

[ghost]

@Korkman it's still manifesting with that ROM.

I've disabled JIT, JIT68k and QuickDraw acceleration - nothing helped. Maybe we can find a clue in the game's readme?

4.  Virtual Memory settings and other System Information

Open the Memory control panel and make sure you have Virtual Memory set to at least 96MB. If you need to make any changes to the Virtual Memory setting, you will need to restart your machine before they take effect.  Virtual Memory does not need to be on if your machine has 96MB RAM or more.

On some computers, the game may seem to pause for a moment (usually 1-3 seconds) in which the computer becomes unresponsive.  This is normally caused by the MacOS Finder running in the background.  To alleviate this problem, enter windowed mode (Command + F) if necessary, and select the Quit the Finder item under the Options menu.  A check will appear next to the item when it is selected.

If the Heroes III Complete game is running slow, be sure to close any programs open in the background. You may also use the Quit the Finder option as described above.  As a last resort, you can open the Extensions Manager and disable extensions that are not in use. Consult the Mac OS Help. (Command + ?) for instructions.

Another way to crash it is when you don't have sound enabled. Just noticed that with a fresh 9.0.4 install (but old nvram). Go to sounds control panel, output and click on "Built-in". Then use the volume slider, it should emit a beep. Then try launching the game again.
