Trying this new english forum out.
I remembered along time ago that certain functions in userlib set the alpha-lock flag with a method that no longer works on new ams versions. So I checked user-lib source in the preos distribution and it was still there.
Also did you know that the estack is 16k by default? There are rom calls capable of resizing it. This could free a precious 16k for other uses like a very memory intensive game like Sonic.
Nice to see a fernando update. It used to be one of my favorite games, when I used to play games.
