Hi there, I’m playing the Mac version too and I can’t find any data files in the game package, there is nothing of use in the Resources folder. Instead I can edit xml files located at the following address:
/Users/YourUserName/Library/Preferences/kudosrocklegend/savegames/nameofthesave.xml
There is a bunch of stuff in the save files, for instance I can set the parameters of the practice mini-game. After some time it gets harder and the sequence goes way too fast, I changed that to 90bpm and it seems to work quite well. Modding the save file is annoying, the changes are not permanent, but it’s better than nothing.
<practice>
<bpm>140,134,132,130,130</bpm>
<inst>2</inst>
