it works flawless on nullDC on my side, same Zintrick
i completed the game, 1/2 hours longplay (one or two? don't know, times fly when i play this one lol)
on average, it works great
randomly nit-pick things (consider happened on emulator) :
- when i was on fifth stage, the music turned off and after a while, it starts play the boss tune, but after i lose a life, all back to normal
- in each phase before boss-fights, when the enemy talks to you to be clear, the speech itself seem start with a little delay, so the sequence itself ends and the speech is cutted (few secs, if no less)
- little slower than the original rom, but VERY close
- not a single crash, or framerate slowdown
