Ok a couple of noob questions here, just to clarify some things
1. Why is it called 3in1?
2. whats does MK3/MD5/32X stand for?
3. Does the 3in1 supports multiple roms that you can select from a menu when you start the genesis? (like the PowerPak for nes)
1-It works for the different types of ROM's. Master system, Genesis, and 32X
2- Those are the abbreviations of the imports consoles
3- If the ROM is compiled with all of them in one ROM then yes.
This isn't ever going to see the light of day. I have been waiting years and gave up and gave my money to the competitor. I am just glad the NEO PCE has been made as that gets the most use out of all my flash carts/copiers.
