I have the same problem as cat above. I deleted and reinstalled 3 times now. There are 2 deviations currently from the instuctions:
After renaming the global emulators (example).ini to remove the (example) from the filename. I startup HLHQ and it DOES NOT prompt for the HL location. However in the INI file it shows ..as the HL path which is correct.
No systems on the left. I try to add one, then I click the "set default emulator" mag glass and HLHQ crashes into a pile of crap.
