Release 0.8 page (https://sourceforge.net/projects/gpsmid/files/gpsmid/Release%200.8/) contains debug .jar and .jad files.
But WTK emulator rejects .jad because it references non-debug names:
The third one has to be changed to launch WTK emulator.
No idea about the second.
The first one has to be without -debug part (should be equal to some string in a .jar file and this line is without -debug part) or WTK won't accept it too.
Should -debug builds be put into a separate folder and have names without -debug part, or should be they patched deeper to have -debug part in all places - no idea.
