edit: für alle die das Problem auch haben hier die Lösung
To fix the bug that causes C&C1 to crash when you move a unit near the edges of the map, disable advanced text services in Windows:
- Go to Control panel
- Open the "Regional and Language Options"
- Go to the [Languages] tab
- Click on "Details..." button
- In the new window that pops up, go to the [advanced] tab.
- Mark the checkbox "turn off advanced text services"
If that does not fix the crash problem try this addition from Komfr:
I had crash when unit with long visibility range (commando, APC) moved to the top left part of the map. The game probably has bug in handling situation when part of unit visibility range circle leaves the upper part of the map and will access incorrect memory address.
Whether or not will the game crash depends on what the content of this memory is (more precisely if it contains some data or if it is marked as invalid by the OS) which in turn depends on type of OS and presence of various programs, drivers or services. This might explain why some people have luck with disabling the advanced text services while it did not help others.
It is possible that this bug was always there, just it did not cause of crash on older and much more forgiving OS. In my case I was unfortunate and disabling of the advanced text services did not help so I looked into the crash and found workaround which prevents the crash for me. Note that this is not correct fix, just dirty modification to prevent the crash and might not work in your case.
The workaround is following. You need to open the c&c95.exe in hexadecimal editor (for example PSPad) and do modifications mentioned bellow (backup the file first). The modifications should be applied in following way. Line 00022821: F6 E9 means that at hexadecimal offset 00022821 within the original file, there should be byte with hexadecimal value F6 and you should modify it to hexadecimal E9. Basically there are two continuous blocks of values you need to modify.
00022821: F6 E9
00022822: 04 5E
00022823: 03 4F
00022824: 04 0B
00022825: 75 00
00022826: 3E 90

The error message displayed during the crash (it appears behind the game when the game appears to hang, just alt+tab to see it) in my case started with "The instruction at 00432421 referenced memory at". If the address of the instruction is different, this modification will not help
