Hi, i ran into a few problems with my kit. I too have SD card slot that doesn't lock in but the spring works and im able to access the romsbut can be easily pulled out . My other issues is the the settings never saves my settings. My Neo geo has a good battery but resets to default. I was getting some artifacts when browsing through the games list. When i boot i see these lines above the uni bios. Oh and my in gane reset stopped working. It only switches games. When i try reset to menu it flashes then restarts the game.
