The translation freezes at the main menu in 50hz on real hardware.

The same does the japanese rom.
This can be replicated only in zsnes (force as pal in the loading window).
How can this be fixed?

mod your console for 60hz  or buy NTSC snes.

I recommend playing this on a real SNES system in combination with the FXPAK Pro flashcart.
The FXPAK Pro automatically adapts the ROM to the given console you are using, but I think you can also force NTSC/PAL modes with it.

There are a fair number of games targeted for 50Hz that reliably crash when played at 60, so I'm not at all surprised that the opposite is true. In the case of 50 > 60 my understanding is that the lack of VBLANK time at 60Hz (and 525 lines) is often the culprit; no idea what would cause the reverse issue, but I'm sure it's something arcane and hard to debug.

Can it also be a vblank issue in my case? In 50hz the title screen is blank, music plays, but i can't press any button. If I switch it to 60hz, the menu appears, I can start the game and switch it back to 50hz and it works.
