Let's get back on track folks.
I just did a little cleaning up in my game dirs to make it look "right".
Renaming drawers, e.g JagarXJ220 to Jaguar XJ220 and RuffNTumble to Ruff 'n' Tumble.
However, the TOOLTYPE problem is back now, NewIcons is added to user-startup and worked great before I renamed the dirs.
It seems that TinyLauncher doesn't like spaces in drawer names.
Games load fine though, TOOLTYPES is just not recognized.
Painstakingly replaced all spaces with underscores, still not working... aargh
Now it works.
.slave .info (including slave name in icon of course) and dir has to be named exactly the same.
