LUA script download:
https://pastebin.com/raw/BQE6MM8c

Instructions:
- Open the above link, then right click -> Save As..., then save it as a .lua file (e.g., "mm5_wily_press.lua") 
- In FCEUX, File -> LUA -> New Lua Script Window, then Browse -> open the downloaded LUA file above, then Start
- Text should appear in the top right of the FCEUX window
- Use the defaults Select + directional buttons to change the patterns (Select + Left combination will change slot 1, Select + Up is slot 2, etc...) 
- The script is expecting you to start before battle, and will reset entirely when Wily's HP is set to a non-zero amount. Starting the script or reloading savestate in battle won't cause any issues, the script will just catch up on the next cycle. 
- Closing the script will resume normal gameplay. All that this script is doing is freezing RNG in a logical manner for Wily Press 

Configurations:
- Open the LUA script in a text editor. At the top, the button configurations can be changed to any input combination per pattern
