I bought some Gals Panic S boards from @ArcSys101. One board in particular is having some graphical issues. Unfortunately, it wont go past this screen.
I tried other carts on this board with similar results. I ended up pressing what I thought was the on board reset button, below the bios chip, a few times and that resolved the issue for some reason. I did however clean the jamma and cart contacts with no results.
Not sure why pressing the reset button multiple times did tho.
I don't have any clue. I'm assuming a korean bios since these were korea based games. I will add stickers to those eeproms. This is how I received it so I wasn't aware. also, i am a noob, so there's that. in any case I'm continuing the convo over on Kaneko supernova region problem.
