Ok so when I added the US set versions 1 and 2, as far as I knew those were the only US versions. However if you search for this game online to find a rom to play. You find Sets 1, 2, and 3 (old version). As far as I can tell Set 3 (oldversion) is what the labeled the original version of the rygar US cabinet. Then they have the "set 2" and then "Set 1" both set 1 and set 2 have the corrected title screen etc. They seem to be the same version. I believe (complete conjecture) that one was mislabeled after they made the Set 3 (old version).

If I'm wrong I'll switch it to 3 separate categories. But for now I'm only having the 2 which I can easily tell the difference on based on Title Screen saying. "All Rights Reserved" vs "All Right Reserved". But if there is an actual difference. And people are willing to show the rom version CLEARLY I'll make 3 categories. Then again you can just rename things.....

On https://www.gamesdatabase.org/mame-rom/rygar

Nicola Salmoria added Rygar (US set 1). Changed 'Rygar (US)' to clone '(US set 2)'.Added new audio cpu rom to (US set 2)

Corrado Tomaselli added clone Rygar (US set 2). Changed description of clone 'Rygar (US set 2)' to 'Rygar (US set 3 Old Version)'. Renamed (rygar2) to (rygar3).

but in the post The differences between the US (set 1) and US (set 2) are :

• 'Set 2' has a bug in the code which lets p2 start a game when p1 is already playing. You need to set a dip-switch to enable this behavior (it is usually on by default). If you press '2' while p1 is playing a single player game, 'Set 2' will check that you have 1 or more credit before it registers that you're now in a 2 player game, but it won't deduct the credit. That's a bad bug and probably accounts for why a bug-fix version was released.

• In 'Set 2', if p2 starts while p1 is already playing, it says 'playre2' instead of 'player2' at the top right.

• The first screen of 'Set 2' says 'ALL RIGHT RESERVED' - missing an 'S' - that's fixed in 'Set 1'

There is no mention of Set 3, If someone can show me that there is a difference I'll easily edit and set the runs up with 3 sets.

If those are the only differences I'm not even sure if I need different categories at all honestly.
