maximum number of DAT files supported?

[ghost]

Hi!

I'm making DAT files for MAME and write my own LUA scripts to read them.
When trying to load more then 5 DAT files: the 6th, 7th, ... files don't appear in the tabpage and also not in the DATs view.

Download them here to try:

I want to ask if there is a limit on the number of DAT files MAME can display at the SAME time in the user interface?
However, the contents of ALL DAT files is inside the file history.db (so they ARE read and put in the database)

Thanks

So in other words: is 5 the MAXIMUM number of DAT files that can be displayed in the user interface?
