Quoted from Fezmid:Had a weird bug pop up on the game today and was wondering if anyone else has seen this. I loaded the cannon and got multiball twice. I then loaded the cannon again, it told me I had to hit 3 targets (so far, so good). I made my shot, managed to hit two targets with one ball, so it said I had 1 target remaining. I load the cannon again and it says I have 255 targets to hit! Umm... But only one target was blinking, so I thought no big deal. I load the canon again, and this time it says 254 targets to hit, and there are NO blinking lights.... Uhh.... Unfortunately, after the ball launched, it went SDTM so I didn't get to try again.
Anyone else see this and know what caused it?
Haven't seen it myself, but it looks like an example of decrementing an unsigned storage register past 0, in this case 8-bit "underflow". Maybe the system thought you hit 3 targets? The two's complement of -1 in this case would be 255, and would make sense if you hit the target again to go to 254 (-2); I doubt the designers worried about "negative targets" to hit, but then again the maximum is 5.... Did it last through a power cycle?
