First you msut let us know how you have your OS installed. Because Tiny Launcher under WinUAE must be executed from hdf FileImage - not from directory mounted as Hard Disk. And if you want to use tooltype settings to read tooltypes from executed *.info files you have to be sure NewIcons application is executed in your S:startup-sequence or add something like that befrore loading OS to S:startup-sequence:
Run <>NIL: C:NewIcons
You can swith tooltype option by pressing T key. Paths to games/demos may be set by C key. WHDLoad games with *.slave are required or *.tl scripts for executing by yourself. I'm not too good to write total newbie quides. In my opinion usage of Tiny Launcher is really trivial. More information you will find under H key. Just remember my information about hdf file and sets more than 2 MB of Fast memory. Thats all. So practice a little bit and you should do what you want to do. And always remember to press F1 for each catefory if you change paths or added new games/demos to directories.
