World heroes 2 compatibility issues

[betamaxizhuge]

Hi all, upon plugging the World Heroes 2 cartridge into the Family Computer I'm greeted with a screen error message and broken mucked up graphics, I'm wondering if this means it's a non-compatible Famicom cartridge and will only work on Chinese Famiclone type systems, I know this sounds petty but this cartridge came with a hefty price tag - if anyone knows about CONY soft cartridges and has had similar experiences with their World Heroes 2 title please fill us in with some info it would very much appreciated.

Thank you all

The error message I'm greeted with is F SCREEN ERROR

I remember one of their games (maybe this one) had option of selecting pal vs ntsc mode at the title screen.

IIRC, this game works fine in my Twin Famicom.

[P]

I would try cleaning the pins.

That's the first thing I tried doing long before posting problem here on Famicomworld but thanks
