Had I known Centipede was such a controversial topic I would have started this thread with an abortion joke to lighten the mood. This is what I chose as my hobby ffs.
mecha has helped me out in the past as has andrewb. I respect both of their technical opinions as well as yours Hudson. Although I must say you do come across as a bit of a douch. The game actually does have POKEY issues as well according to my research. However this bug is what currently intrigues me.
If the mux output of P5 was messed up couldn't that make the trackball data be written to the wrong memory location? This is my current theory after looking at the schematics.
Hudson, please don't squelch other people's speech in my thread. This is a community effort.
I'm armed with an oscilloscope, digital probes and a multimeter and I'm not afraid to use them!!!
Y'all want to have some sort of ganglia contest, fine! I challenge everyone in this forum. I'll provide absolutely no measurements only symptoms. Everyone is welcome to make a guess. Afterwards we will see who was on the correct path.
This game has been sitting in my game room for two years now. This is my hobby. Entertain me humans!
I'll post a video soon.

You're correct sir. I was speaking in technical shorthand.The trackball doesn't "write" to anything.
Interesting choice of words. Wouldn't it be more appropriate to say "The MPU reads the trackball data and "writes" the archer's location to the proper memory location."?The CPU reads the trackball, and modifies the shooter position based on it.

You sure about that. Boy what judgment you've passed on me.If I do (b) the OP doesn't know the stupid post was stupid.
