Hi,
I hacked wine to enable 3GB user address space just like the /3GB boot.ini
option for windows. ( see patch )
This actually works like a charm playing everquest2 which crashes from
time to time without this patch due to running out of memory.
To do it right, should this "3GB Option" be enabled by a wine start
parameter or a registry key ? Is the registry already setup during the
call of libs/wine/mmap.c ?
Bye
