Issue regarding custom stages

[TrueStorySeamus]

Hello,
I recently started adding new character textures and I'm loving the creative, talented work that you guys are putting out there for the community! Though it isn't all sunshine and rainbows for me regarding another section; that being the stages.

No matter what stage I download and put into stages/melee folder, the end result always ends up freezing my game and having to reset. This even applies to stages that have an .rel file included.
I have absolutely no idea what I'm doing wrong! I change the names to the ones listed and when an .rel file is used, the .pac file is the same except for the STG part.

If it helps you, I'm using a PAL version of the game from England, and use Riivolution 1.04 to run the game.
Any support to this issue would be greatly appreciated. Thank you very much for your time.

A PAL user... I'm pretty sure most of us here use the NTCS version. But not entirely sure if that'll affect anything. Is your File Patch Code PAL too?

Not sure where to check that, but I'd like to think that if my game disc is PAL and because I'm using the RSBP folder name.
