I made my own DOS implementation (Announce)

I noticed that the symbolic links were completely broken. Now it seems to handle all corner cases correctly.

 Thanks. I fixed that.

 I don't understand what you mean. But syscall 44 function 09 does not have to exist when MS-DOS compatible networking functions are not loaded, so that's not necessarily a bug in ST-DOS. Other DOS kernels just don't show that error message, and I intend to hide it in future versions.

 Memory control blocks in ST-DOS are different than they are in ST-DOS.

 The game may have corrupted something in the memory. Not necessarily a bug in ST-DOS.

Instruction set extensions have nothing to do with security. If anything, unconditionally requiring these new instruction set extensions worsen the security, because that prevents some people from updating the software to the latest versions.
