MAMEWorld Forums - Emu Loader - Software List not updating, or displaying new additions

Having installed MAME .247 and using EmuLoader's "Create MAME Software Games List" option, it generates a software list. But when I open up the a2600 machine with the software list displayed, it's missing a number of games in my software\a2600 folder. It sees the "standard" Centipede, for example, but not the new Centipede (prototype).

I can confirm that both games are located in that folder, so why is EmuLoader not finding it? Could it be an issue with the software last embedded within the MAME .247 executable?

Thanks,
Paultup
