The game apparently has anti piracy that causes the opening screen to loop forever. Which is exactly what happens in Ares.

This isn't uncommon with pirate games: they often have extra hardware in the cartridges specific to that game, in order to prevent playing on flash carts or emulators.

In order to run these, ares would need to emulate every single cartridge variant ever used by a pirate rom; which at the moment isn't really worth our development time when not a single commercially released game, or homebrew title, uses the same hardware.

It's just a crappy form of copy protection. It has absolutely nothing to do with "running it in an inaccurate emulator". https://archive.nes.science/nesdev-forums/f12/t4417.xhtml
