Night Raid PSX not workign fine

[kelv]

Hello

When starting stage 1 at Night Raid the background is black and I only can see the ship and its lasers... background and enemies are vanished.

I checked with serveral isos and same result. I checked the bios and I have the corrected ones with the right checksum.

Pls, Does anyone suffer that issue?

Thx

Sorry for upping this topic again but in REcalbox 6.1.1 I'm having an error message stating that it's an issue with the bios... no playstation bios file found add for better recalbox . However I have the right bioses with right checksums. Any clue if is this a bug?

thx
