I have confirmed that with the repaired AES the MVS converter works with all my games but World Heroes 2. That game does work on my Omega, so i dont know why that is. But yeah, it works fine with everything else, you may just need to reseat the cartridge sometimes. I played all my MVS games at least 5 minutes to make sure they worked.
Let me know if you are interested. Like i explained in my sales thread, it comes as new with everything, with minimal sign of use if any, and two boxes. One glossy flashy one, and one plain with minimal printing on it. I can provide pics if you want to. Im in Sweden, just so you know.
