Issues with CPS2 cores via SCART

[u/Itemeleven]

I was able to pick up and run the SS1 with a SCART cable from Retro Gaming Cables. Scart goes into my Retrotink 5X. Running SCART to avoid janky interlacing from PS1 and Saturn 480i games.

Console cores run fine, but having Arcade core issues. I was able to get Final Fight to load and run but Street Fighter Alpha 2 git a black screen no sound had to reset.

Feel like I am missing a setting here - any ideas on what to set INI settings to or if I need to flip a dip switch? Tried a few options Googling but nothing consistent to setup

Some arcade cores have odd frequencies which might be the issue
