impossible to run Ocha-Ken Hot Medal

[rguisados]

Hello, I am not able to pass the TEST MODE of this game. I get open doors error and other various errors.

I use Demul and the latest bios and roms. I've been trying to get it working for a week with no luck.

I saw the video of the partner p1pkin that gets into test mode in debug mode but I have no idea how.

Could someone help me: I would really appreciate it very much
