Okay, whenever I try to run Assosiate_Shell.bat, I get an error message saying "A file cound not be found. I'm using 98. Thanjks for the help!
This is probably a lack of "reg.exe" on your computer (a command-line registry editor, standard with some newer versions of Windows).
If you want to do this manually, remember the name of the PKSV folder (mine is located at C:\Documents and Settings\Charles\src\PKSVUI) and we shall refer to this as FOLDER.
Go to registry editor (start->run, regedit, OK) and expand the "HKEY_CLASSES_ROOT" (this may take a while) key if it is not done so already. Then right-click it and add a new key. Name the key ".pks".
Go to the new key, and there will be a default value in it, double-click it and set it to "PKSVScript".
Then go back to the top and create another key in HKEY_CLASSES_ROOT called "PKSVScript" (yes, that again :P ). Set the default value in that key to "PKSV Compiler Script", then right-click the key and press new key. This should create a key INSIDE PKSVScript. Name the new key DefaultIcon, and change its default value to "FOLDER\pksvui.exe,2"
Back in PKSVScript, create another new key called "shell". Set the default value to "edit". Then inside "shell", create a new key, "edit". Set the default value to "&Edit".
Inside "edit", create another key called "command" and set the default value to ""FOLDER\pksv.exe" "%1"".
Back inside "shell", create yet another key, "comp". Set the default value to "&Compile". Then create a new key inside "comp" called "command". Set the default value to ""FOLDER\pksv.exe" -r "%1""
And then you should be done.
