It has a vertical monitor, so no 2d fighters. I want to turn it into a dedicated cab or something; what kind of games came in that type of cab? I also have a klax cab, but im putting a cps2 game like xmen vs. street fighter in it.
Assuming it is a 19" monitor "cut-corner" Dynamo cabinet (HS-1), then Ikari Warriors is the original dedicated game to use that cabinet:

There is a good chance that your cabinet was originally an Ikari Warriors in fact.
Victory Road (Ikari Warriors sequel) also used that cabinet, as did Guerrilla War (Ikari Warriors' first cousin), as well as the same controls and control layout. For my Ikari Warriors cabinet, I have all 3 boards to swap in it, plus Heavy Barrel (not SNK but it still used the same controls and layout). There are several other rotary games that work with Ikari Warriors controls too.
Though Ikari Warriors boardsets were manufactured with a JAMMA connector for the conversion kit, the dedicated version (which is far more common) used the 44-pin SNK pinout. Most of the other rotary games were JAMMA. For my machine I wired a JAMMA connector in parallel with the SNK connector to allow board swapping without a JAMMA adaptor.
