a couple (probably simple) ms pacman problems - sound / fruit issue / cut scenes

alright, working on a ms pacman board, but came across a few minor issues:

1 - ms pacman graphics are correct, but game plays the pacman plus music at the beginning of the game. what rom/ram controls that? is it 2L and 2K?

2 - when you gobble a fruit, the points stays on the screen where you eat it, until the next fruit comes out, or you finish the level. not major, just weird.

3 - i changed out the speed up chip for a stock speed chip (just for testing), but it didn't change the speed? not major, but why would changing out chip 6F for a stock chip (tested in another pac) not work on the speed?

4 - the cut scenes / acts are weird! first one, 4 ghosts chase each other, 2 of them moving backwards. 2 of them move up together, the other 2 bump. i like it, but what chip controls that? video link below:

thanks in advance.

Perhaps it's a hardware speedup rather than software?

Not sure what chip, but I can tell you that the ghosts that move up are supposed to be mr and mrs pac.

yep, and there's supposed to be a heart above the 2 ghosts that should be mr/ms pacman, but instead the purpleish ghost disappears after the bump, and moves above the ghosts that represent mr and ms pac...ha.

i've had clay's 24in1 pac, but have never seen cut scenes like i see here. makes me want to play some Ms Hakman.

the only thing i'm going to fix will be the pac plus music...the rest of it stands alone as a unique game, as i already have a complete ms pacman right here. just curious what's causing the differences.
