This is Version 0.92, so it is not the final version yet but its the first full release.
Since its  a first released there could be glitches here and there and even major glitches which i am not aware of.
Obviously i cannot guarantee such, i will make sure the game boots and save but thats it.

from what i read some people played all the way to chapter 4 and no problem, also read in youtube comments that  another guy wrote,  the music stop working after defeating a boss later on, could be due to the emulator or even a glitch on  real console i have no idea as he did not write more details.
Stuff like that are to be expected in the first release on a game.
i can also sell n64 programmer for 60USD to update your cart at ease from home when new version comes out.
