Sorry I wasn't lear enough. Ok say u already hav ethe converter with the bios debug chip,. can u tell a MVS cart to boot up in AES mode, where u have an option meue and practice and such?
Yes, G', you can. The code is the same in MVS and AES carts. It's the BIOS that tells the cart how to boot up. You can have the home options of a MOTW cart using a Phantom and a home deck.
