I was wondering if it was possible to replace the Dracula's Castle stage with
this Luigi's Mansion skin with the hackless Wii download.
If it's possible, how do you do it? If not, it's ok, I was just wondering.
It is possible. Have you inserted textures before?
If so, just download the STGMANSION.pac and replace the current one. You might want to back-up the current one just in case you ever want to switch between the two textures.
If not, follow these steps:
In your SD card, go to private>wii>app>RSBE>pf>stage>melee
Download the STGMANSION.pac and drag it into the melee folder. When it asks if you want to replace files, click yes (if you want to switch between textures, back the current one up). You should be done. This method does not replace the icons on the stage selection screen, only the stage itself. If you want to fully replace all the icons into Luigi's Mansion, then research more on BrawlBox.
Hope this helps.
