@Legion in cases like this, i always recommend checking Steam Input and resetting it to the recommended preset or the basic controller preset.
Sometimes, when Steam updates it, there's a slim chance it creates some funny, dysfunctional mappings.

Any idea why Y doesn't work? I rand 2 different programs to check and see if maybe, just maybe, my button was bad...but it isn't. For some reason Y just refuses to register in this game.

Thank you this actually worked

If possible you could apply the patch on a Windows PC and replace LINKDATA2.BIN and LINKDATA2.IDX on the Steam Deck with the patched versions.
Otherwise these are the 4 relevant commands:
LinkdataPatcher.exe LINKDATA2 4689.dat 4689
LinkdataPatcher.exe LINKDATA2 4690.dat 4690
LinkdataPatcher.exe LINKDATA2 4695.dat 4695
LinkdataPatcher.exe LINKDATA2 4696.dat 4696
but you would still need to run them via Proton. I guess you could add LinkdataPatcher.exe as a non-steam game and set the start parameters to LINKDATA2 4689.dat 4689, ... one after the other.

Thanks

I used some rickety custom scripts, that I couldn't share without some major cleanup.If you just want to extract the textures, I think https://www.xnalara.org/viewtopic.php?t=1001 might be your best bet. There is no official support for the PC version of Bladestorm. But Toukiden Kiwami uses the same data layout, so it should work with that option.

How did you extract the textures?

That was so easy, thank you so much!

thanks fam

Small problem. I installed the patch, and I see the prompts properly, the problem now is it doesnt recognize my controller when I try to use it! (I tried disabling Steam Input as well)
