Ways to run bios only?

02 Sep 2019, 20:50

Is there a way to boot only the bios for Sega CD, so it's like there is no disc inserted?

I would also like to do this for the SMS, to access the snail maze game. Is there a blank rom or some other way to achieve this?

If you just want to see the bios animation, you can just use an audio cd. It will stay in the press start screen with the animated logo.
If you want to access the cd player or backup memory manager, with an audio cd, just press start. With a game cd, just press any button except start.
Ability to properly run a sms bios has been added to the next firmware, you'll just need to load any dummy file renamed as a sms game, and you'll be able to run the internal bios games

An audio CD image. Now why didn't I think of that? Seems so obvious now.
Thanks for the reply! Cheers!
