Bandit Kings of Ancient China emulated.

Hey there.

My mom is a huge fan of Bandit Kings and has been trying to play it again after many years of not owning a console. It appears that the timers the game uses cause it to struggle to emulate properly (visual glitches, missing txt boxes ect)

Can anyone here let me know if there's some kind of fix for this? I'm currently looking into hdmi modding my nes for her as a gift, but what I'd really like is to get it running on her nes mini (proper Nintendo model)

Any help is appreciated.
