Mr. Do! - Treat Scoring Algorithm?

[ColecoFan1981]

In Mr. Do!, is there a specific algorithm (like the one for the Diamond) that computes the score for the treat collected by Mr. Do! on each level up to the 22nd board (scene)?

On scene 1 the treat is 1000 points, and maxes out at 8000 points at scene 22.

If we had the point amounts for each stage, we could just figure out the algorithm.

If we had the point amounts for each stage, we could just figure out the algorithm.

Actually, I remember it was computed this way: it's 500 points + (500 points * scene number), which would work out to:
Scene 1: 1000 points
Scene 2: 1500 points
Scene 3: 2000 points
Scene 4: 2500 points
Scene 5: 3000 points
Scene 6: 3500 points
Scene 7: 4000 points
Scene 8: 4500 points
Scene 9: 5000 points
Scene 10: 5500 points
Scene 11: 6000 points
Scene 12: 6500 points
Scene 13: 7000 points
Scene 14: 7500 points
Scene 15: 8000 points (maximum)

For the arcade version, the computation for the treat bonus ends at level 15 which works out to 8000 points; scenes 16 and beyond will have the treat bonus stand at 8000 points.

However, for the ColecoVision version of Mr. Do!, while the treat bonus is computed the same way, the resulting scoring multiplication keeps going beyond scene (or phase) 15. I know, because in this video where the score rolls back to 0 (maximum points before rollback is 655,350), at phase 59 the treat bonus would work out to 30,000 points.

Wow, that seems like a long time to be playing. Why are the badguys still moving so slowly? Does the algorithm controlling their speed break at some point too?

Don Hodges did a teensy bit of disassembly over here:

I don't know, maybe. We'll need to ask official Coleco programmers about that. People like Zachary Smith or Paul (now Jennell) Jaquays.

The creators of the game should know the exact algorithm, however, I have never played Mr. Do!, but judging by the game play it looks rather fun!

As this is a game from thirty years ago, sir, even the creators have probably forgotten.

Are you only here to promote your website..?

I have to say, Mr. Do! is incredibly fun. I originally played it as an arcade machine at a local movie theatre. I was so sad when I went there one day and the Mr. Do! machine was nowhere to be found. I inquired about it, but it seemed nobody knew where it went nor why it wasn't there. It never returned.
