Debug mode can be succesfully enabled on Samsung GX-1S with firmware 1.02.
Unfortunately, there is no debug menu like on newer cameras.
The same procedure will probably work on all *ist and GX1 cameras.
Only the MODSET and AUTORUN extensions may differ.
1. Format SD card in camera (I tested 16MB and 128MB)
2. Create file MODSET.TXT in root of SD with desired testmode (only one option at time)
3. Insert SD card in camera - DON'T CLOSE SD CARD DOORS!
4. Turn On camera and wait few seconds
modset filename: MODSET.TXT
scripting filename: AUTORUN.375
