Hmm @enthusi also had a problem with the Lynx SD loader, but that's because he copied the LynxSD folder over directly. You need to have the "30bday.lnx" file in the root of the SD card, then the "30bpc19" directory with all the ROMs also goes into the root of the SD card, so your directory structure should look like this...   |--30bday.lnx |--30bpc19/    |--01.lnx     |--02.lnx ...
