Hi
I have some dos games that want to exec dos4gw.exe when starting.
but this seems to fail.
I hope i read the debug messages correctly and the comment from
file:Win32HandleToDosFileHandle is still valid.
what happens is dos:int21 wants to open file with the dos handle and then read
from it.
reading the file calls the function file:ReadFile with the
converted win32 file handle which is invalid if the above mentioned comment is
correct.
Any ideas how to solve this or am I completely off-track here.
Ciao
Enrico
