Mr. Do! - Max High Score 655,360

[ColecoFan1981]

 

Watch as the score resets to zero when this guy plays Mr. Do! - the maximum possible high score is 655,360 before going back to zero due to $FFFF (65,535) being the highest byte number in an 8-bit register.

 

I wonder if any of you ColecoVision hackers know anything about how to hack the ROM set so that the maximum score limit reaches 999,990 points before going back to zero.

65535 is a 16-bit value, actually. The highest 8-bit value is 255, if it's not a signed value.

That kind of thing is possible, I guess, but why would any hacker bother? It's not like every CV fan out there is going to buy an AtariMax USB cart, download the hacked ROM and play it into the wee hours of the night just to see the score go beyond 655360.
