I've got a Japanese Mega Drive (Model 1) and a Japanese Mega CD (model 2). When I start the game, I get the following message:
No Disc Found, do you wish to insert Pier Solar disc? Yes - NO
The disc being already inside the mega cd, I press yes, then it says open the tray, place the disc and press start. I do what's asked but the game tells me the disc is not to be found.
However, my mega cd works perfectly on its own, if I insert just the CD and not the cartridge: the motor starts and I get a message telling me that this disc is to be used with the cartridge inserted.
Any advice on what's going wrong and why the game doesn't recognize my Mega Cd?
