Irem M72 multi kit installation & support

Just played through the first boss of Ninja Spirit and noticed the slowdown. I don’t know how to count frames but 25% slowdown like @ShootTheCore said feels right.

Anyone get to the bottom of this?

Could anyone let me know if massive slowdown is normal on this hardware? Some examples:

- Ninja Spirit 1st boss if you are using shirukens with a few clones and don't kill him right away when he starts firing lots of green projectiles

On my boardset it goes down to what has to be single digit FPS during these parts. Not having owned the boards before I'm not really sure what's correct and it's hard to tell in MAME what's "accurate" slowdown.

I've been playing Ninja Spirit a lot lately. Here's a PCB capture of a Japanese version PCB (not the multi):

I believe the slowdown is probably normal. The game slows down a lot on the first boss because of all of the projectiles. Stage 6 is another area where the slowdown hits hard. There's just so much action going on at once. I have a multi too and I haven't noticed any discernible differences in the slowdown, only region differences in the gameplay.

Yeah that looks about right. Thanks for sharing that. Glad it’s normal operation. I didn’t get passed the first boss as quickly as in the video
