you put the wrapper and it's lconfig.ini in the emulators folder.....
your new command line will be:
C:\project64\cmd-launch5.exe "C:\project64\roms\Hydro Thunder (U) [!].zip"
in the lconfig.ini you set a few settings... the most important one being the emulator, which you will set to project64.exe
the translation data between the cmdlist brackets can be deleted as they won't be used (not the brackets themselves though)
your done
btw all of this is in the online documentation
Thanks Howard, I actually skipped over the above post when I was writing about key-remappers.
It's clear enough now, but the online documentation doesn't cover this example, for instance, doesn't say that the cmdline wrapper will work in this case, even though Project64 uses Keypresses. Seems like a very good solution, though.
but I have a quick suggestion . . .
It seems like there should be two more .ini file options -
Desired Esc Key =Esc
Exe's Esc Key=Alt+F4
Since these aren't listed, I assume the wrapper just waits until you press Escape and then issues an "End task" to the program that is running.
Maybe the second command isn't needed, and the first one would only really be useful say to someone with a small encoder that didn't have Esc available, or . . . well, ok, I can't think who it would be useful for, but someone might want a key other than Esc (but settable) to exit the .exe.
