Zero4 Champ DooZy-J Type-R (Japan) // No boot after the SEGA BIOS logo screen

The game stays on a black screen after trying to boot it with core version 2025-07-18.

Maybe a regression, I'm checking it right now.

After some checks, the game was playable on older core versions.

I tried with core version 2025-01-11 and the game works.

The last working version was core 2025-07-15.

The recent changes on 2025-07-17 created a regression that game.
