there's also a missing priority effect I wasn't aware of where you can see some enemies in the background before they appear... (first time I've seen original footage of this one)

looks like my sprite enable bit is actually sprite priority, not sure why this wasn't pointed out when the game was first dumped and I did the driver.

the music tempo is odd, drivers says the 2203 clocks are measured, only way to speed it up I can see is to adjust them. might be like Street Fight which also has a 2203 and need a hack.

I fixed the sprite priority to match the video, unfortunately the video doesn't repeat the steps to trigger another annoying visual bug that i'm almost sure is a real game issue. (force scrolling the enemy at the top off rather than fighting them results in sprite glitches before a new enemy appears abruptly)

Adding Guru's recent video for another hardware sound reference.
