Playing Super Mario Bros. cabinet

[JJFBlaster]

I don't know if this is the right forum to post in, but here goes.

 

I have been reading many discussion posts on how to download the ROM and get it working on VPX, VPinMame, etc., and I cannot seem to get this game to work. I get get other tables to load properly, however. I do not know what I am doing wrong, so if I were to uninstall everything, what do I need do download and modify to get it to work?

 

The games I am wanting to load are Super Mario Bros. and Super Mario Bros. Mushroom World.

 

Note: Some discussion posts claim solutions that lead to other posts, but please don't do that, because sometimes they lead to dead links and it infuriates me.

Note 2: I also attached a screenshot of the "game info," which says I'm missing a ROM set. I can't find them individually outside of downloads of the ROM itself, and they're all the same download, making it unhelpful. If that's the problem and someone knows how to fix it, please tell me how to fix it.
