I would love her to completely replace rouge throughout the game, but for now it's just the most noticeable things (still more than most character skins!).
The character model is based on Rouge in Amy's outfit by MainMemory.
Places you'll see Cassy:
- In-game as rouge in levels and chao garden
- On the stage select / story select screen
- Lifes icon / 1up boxes
- On the story character recap
Things I have yet to replace:
- Main background collage with all characters
- Chao drawing portrait
- Story screenshots
Things I wasn't able to figure out (any help is appreciated!):
- Cutscene models (help thread here)
- Kart racing
- alt costume
- story recap text
- load file character
- change the level loading color from rouges pink
I recommend using the Character Select Mod, so you can also use her on all of knuckles levels (hold up on the control stick).
