Unfortunately its not easy to identify the 'version' of a ROM.

You'll need to run a desktop version of MAME and do a Rom Check. If it passes with the current version then it may be the newer ROM and it may be the problem.
If you run version .36 final of MAME and the rom Passes, then it should be the right ROM. Again the game may pass the check but it may be one of the Games that are still not operational in MameCE3.
Hopefully I will get the next build finished soon and then the newer ROMs should work again.
