Need Help with 7th Heaven Modding for FF7 on SteamDeck

[IceKing]

Hey everyone,
I've been trying to mod my Final Fantasy VII on SteamDeck using 7th Heaven, following the instructions in this YouTube video - https://www.youtube.com/watch?v=yCRSohE2r_E and the associated GitHub repository - https://github.com/dotaxis/7H-SteamDeck-Fix. I've successfully installed 7th Heaven and managed to run it without issues. However, I'm encountering problems with getting any mods to work in the game.
Here's a summary of my issues:
* Mod Installation: After the first start of FF7, any mod I try to add doesn't seem to work at all. I've reinstalled 7th Heaven and even the game on Steam, but I'm still unable to make the mods work as intended.
* 60/30 FPS Gameplay: While the 60 FPS mod is working, it seems to be functioning incorrectly.
* [Tsunamods] Echo-S: When I enable the Echo-S mod, there is no sound in the game at all.
I've scoured forums and guides for solutions, but I'm hitting a wall here. If anyone has any advice or suggestions on how to resolve these modding issues, I'd greatly appreciate it. I'm eager to enhance my FF7 experience, but these technical roadblocks are causing frustration.
Thanks in advance for any help you can provide!
