Works fine for 0.993g for me.
"Simple" how-to for non-Windows users:
Download the .bat
Open it in .. something. Whatever your text editor of choice is
Open
You must be registered to see the links
(or however you want to do the decode. I was lazy)
Copy/paste the rpatool1/2/3/4/5 blobs in order as one long blob and decode, and save that as rpatool.py somewhere (or you can download rpatool.py from another source, if preferred, or use your existing one if you have it)
Do the same with cheat1, saving that as cheat.py in the game/ folder
Copy archive.rpa to where you put rpatool.py
Open a terminal in that directory and execute
python3 rpatool.py -x archive.rpa
Copy options.rpy and screens.rpy from there to the game/ folder
Open a terminal in game/ and execute
python3 cheat.py
Should work fine
You can then delete the
copied archive.rpa + extracted contents, if desired
