How to patch non-VGA games to play in VGA mode with any VGA adapter
Some games cannot be patched such as: Bangai-O. There isn't any patch tool, you have to manually.
You will need a hex editor.
-open the file in the hex editor
-search for the string "KATANA"
-shortly after, you should see "JUE" followed by some numbers
-change the number string after "JUE" to "0799A10"
-save the file (I recommend over-writing the original file)
Works like a charm every time.
