: sigh, most games use XMS and EMS as drivers which are usually defaults on

I'm not sure if I have a similar concept of what driver is, but IMHO a driver
is something that has to be started in the rc.local, config.sys, System Folder
(whatever your system is), e.g. setting the EMM386 to support EMS while you
usually prefer not to use it due to memory loss or loading a VESA bios
extension. Extenders like dos4gw and cwsdpmi don't really count as drivers,
since they are loaded at startup (I would say).
As long as you can unzip your shareware program into an installation directory
and then run it from there, I think nobody will complain.
Compared to dos4gw, go32 and cwsdpmi work better BTW, if you want to run
a Watcom 32bit program from a different directory, you have to supply the path
to the extender also (d:/foo/dos4gw d:/foo/prog.exe) since it only looks in
the current directory and maybe the PATH, while cwsdpmi is also found in the
directory the program is found in.

I though so too, apparently the largest setting in the list is 16M, but you
can also enter an arbitrary number manually and then the limit is 64M.
(Though 16M should be plenty, this means that the compiler can allocate 8M
in one block, which he probably won't do anyway).
