Daphne LD filenaming doubt

[derebo]

Hello,

The Daphne Docs article clarifies that how the folder structure shold be named for proper recognition by the emulator.

However, what about the videogame filenames? In the exmple, there are
lair.m2v
lair.ogg
And the Daphne compatibility list the are many game types ("rom names" so to say). So how to tell if a given LD videogame is properly named when there is no .dat file to compare it against?

To add more confusion, Daphe Loader will name Galaxy Ranger as galaxyr when there is no galaxyr in the compatibility list. Astron Belt is named
astron512.m2v
astron512.ogg
or Badlands
badlands-pc.m2v
badlands-pc.ogg
which, again do not match any game type in the compatibility list (astron astrop badlands badlandp respectively)
So how to know what game type those files (m2v ogg) actually correspond to?

Thank you for your attention in advance,

@derebo The ROMs with pat the end are for the Pioneer board. From the .txt file inside of one:

Pioneer version of board uses same ROMs as Hitachi version,  
except 5473c and 5474a are not used, and IC3 (5596) and IC10 (?) are added.  

NoTE:  The ROMs in IC3/IC10 on my board are apparently not the same 
as the 'standard' ones.  I was told that these ROMs did not work when 
swapped into a board that had a different set, and vice-versa.  If I can find 
out any more info (and/or get a dump of the other ROMs), I will!
