These are some simple binary patches to Prism Launcher that crack the official release builds. You can use something like hexed.it to apply the patches.
- Open the main 
prismlauncher.exefrom the official download (make sure it's the right build!) - Paste the location of the patch into the "Go to" box and click enter
 - With the cursor at the right location, type in the patch bytes. They should overwrite the bytes that used to be there.
 - Export the modified binary and replace the uncracked EXE with the one you just patched.
