Ok let's make this quick:
These blocks are pretty complicated to set up.
There are a lot of different files you have to put into different folders and so on.
Your problem is not with uberasm but with gps.
In the folder "BlockRoutines" of the downloaded files you can see the file "FaceYoshi.asm". Copy this file to the "routines" folder of your GPS folder. Then it should work. (last sentence of 5.1 in the readme)
It's not a uberasm routine but a gps routine.
You should probably don't say this is a uberasm tool error when you are running gps (which I can tell because the error mentions the filename of a block and uberasm won't use those files when it comes to the screen scrolling pipes).
Edit: I don't even know why you would call "faceyoshi.asm" with uberasm (first error msg). don't do that. only do what is written in the readme.
