509 in 1 multicart

[FF_]

I received this game cartridge today (509in1). I bought it only because of "immortal the" game. When I turned it on, I saw artifacts, although the wiki says that the game works on old CRT TVs.
I checked on my other TV and it works fine.
Problems that it has - JVC c21ze.
No problems - 21DG16KG.
The image is very dark - Philips 42pfl3604
But part of the screen on the Thomson is moving a little, that's why I use jvc.
