Easy way to use the hidden character skins (No hex-editor)
>Right click on Ghost Master shortcut
>Click on properties in the drop-down
>In this window there are 3 tabs you can click on (Find Target... Change Icon... Advanced...) Click on "Find Target..."
>Open the file in this new window called "GhostData"
>Open the file named "characters"
>Open the file named "GHOSTS"
(From here on is an example of how you would then load up Soul Screech)
>Open the folder titled "SoulScreech"
>Right click on the .bsp file named "soulscreech"
>Choose copy from this drop-down
>Now go back to the "Ghosts" folder
>Open the file titled "Moonscream"
>Remove the .bsp file named "moonscream"
>A window will pop up asking for your authorization agree
>Right click on a blank spot in this folder
>Click paste in the drop-down
>Rename the .bsp file named "soulscreech", change it to be called "moonscream"
>A window will pop up asking for your authorization agree
(This method works perfectly. I have the U.S. version of the game and haven't experienced any issues with it yet)
P.S. If anyone is interested I would love to get together with some other Ghost Master Modders and work on designing our own levels. This threads old, but I found it through a Yahoo search, so maybe someone else will see this and it'll help them.
If you're interested in modding with me, I'll check back on this thread for any responses @ the end of every month till the end of the year.
