Wonderful work! Such great findings.
Yes, the workaround tickboxes would set the template to ID 0 (which is likely unspecified so the defaults are used), so they need to be off and the trons set to the default for the wrestler. So basically, these files are the ones containing the templates that are linked to from the .moveset file (via ID).
Do you know if assetconv.pac also controls the victory music/tron templates or is there a different file for that? Similar question for victory motions.
In any case, this should be the key to create templates for all 10 attires of each wrestler and be able to add different entrances and possibly victories for each of the 10 possible attires for any wrestler, be it available in-game or otherwise (I wonder if there is a limit). This should be great as we could have attires from different eras/gimmicks of a wrestler each have a fitting entrance/victory.
