I was messing with unity with crow 64 and i made everything go visible and i got something new
These images are new i dont know.

I was able to get the image of the strange thing in the walls here it is.

Its actually simple, i used the crow 64 rom (its the source code) which some have made videos on it using unity and while i was messing around i found a way to make everything visible so i did that and thats how i got the image.
If you wonder where the download is i got it from here: https://archive.org/details/catastrophe-crow
