First, thanks for the work. Second, I've gone through a lot of this thread and can't find any help with this:
I edit the batch file with whatever parameters, but when I click on the run.bat, as opposed to the exe, it doesn't run. It flashes up the little command line screen, but immediately closes.
It could be that your parameters are not correct, try this:
freephg.exe <your options here>
This will make it pause before stopping.
It might also be that you haven't got the CLI stuff installed for XP, so you could try this instead:
1. Create a shortcut to freephg.exe
2. Edit the properties of the shortcut.
3. In the box which says "Target" add the option you want (just as you would in run.bat).
4. Run FPHG by using this shortcut.
