Got the EZ flash Omega today. It worked on my GBA for a few test title screens and one race of Mario Kart, but when I wiped down the screen with isopropyl and booted up Pokemon Sapphire to take a picture, it froze in the opening sequence. Now, it sometimes goes to a black screen immediately, sometimes has a glitchy boot screen and goes to black immediately, sometimes goes to white, sometimes boots up and starts a game but then the screen goes black and only the sound plays, and many other problems. It never works for more than 30 seconds, unless I'm just in the menu.
I've tried upgrading and downgrading the firmware, installing custom firmware. I tried cleaning the contacts, reconnecting the screen ribbon cables, the paper trick, different micro SD, formatting the SDs and on and on. I'm using a 64gb card with exfat, also used a 4gb Sandisk with fat32. I think the cartridge just might be trash.
