Unable to run Attack of the PETSCII Robots.smd

[denjhang]

This is a standard Mega Drive game, but when I use blastem to open this ROM, blastem prompts me that I need Sega CD BIOS. This is very strange. When I prepared the Sega CD BIOS, I couldn't enter the game, it was a black screen. Attack of the PETSCII Robots.zip

After I selected the correct cdbios, I found that after entering the game, the game prompts me whether I need to switch to model 1 mode. When I choose yes, the blastem freezes.
