:-D

That doesn't sound like you managed to create the proper HDPMI variant. The file size is no clear indication since it's a PE file with section alignment.

To check that you succeeded: open any of the .lst files in STD32 (Switch.lst or pagemgr.lst) and search for ?NMISAFE. You should finally find this line:


?NMISAFE . . . . . . . . . . . .        Text  1


Btw, the "-2" option is meant to be used for DESCENT - I'm now pretty sure that it's a bug in this game only, not in the DOS/4G extender.

The loading sequence is:
1. JemmEx in config.sys
2. AWEUTIL
3. optional: HDPMI32 (optional with -r and/or -x2 switches)

Then either
4. awemidi.exe
5. <game binary>
or
4. awemidi <game binary>

MS-DOS forever!
