i have a popeye and the game plays fine, but when i first turn it on the main nintendo popeye screen with the popeye head is missing most of the popeye head. also when i play the game and its over the screen goes blank until i coin up and hit player 1 or 2. i assume there must be a problem with the chip that has the graphics on it can anyone help and where would i go to get new chips to replace them with?? thanks for any help.
 
Popeye boards are notorious for developing poor connections in the chip sockets. Carefully reseat all the socketed chips by pulling them out and pushing them back in carefully.

I have one that some strange issues and only on the attract mode of the game. The problem there was the Rom chips had two that didn't verify correctly. They were very close but not right, and the chips would give different crc each time they were read.
 
i pulled the boards and removed every socketed chip and cleaned and checked the legs and they all looked good and reseated them all. i have the same problem still, but i have an additional problem now and that is i have colored blocky lines running vertical through all the images that move. i am going to pull just the 7 or so chips and reseat them again.

go to radio shack and buy a Fiberglass contact brush..and use it to clean and polish the legs on your chips and then put them back in...usually that will make them have better contact.... it's what i use :)


good Luck.

Did you verify the roms?
 
My guess is you have a rom or too that have become corrupted. You will need a eprom programmer to read the roms and an eraser to erase the roms and reburn new images.
 
verify roms?? how? :confused: excuse the stupidity. also if they are corrupted who can burn new ones?? and should they all be done or just certain ones??

thanks

You need a eprom programmer and maybe an eraser or better yet a friend with one.

The rom chips are chips that have the program written to them, Think of them as the software for a computer. What the rom chips do is store the permanent info on a chip. They store things like the sprites or characters, what they should look like, normal and when exploding. They are pretty much the entire program with a few other proms for sound and color.

After time they tend to get a bit ifffy and if you do a check on them (crc) they should match the rom crc's from another game of the same version. Mame is a very good source for this/us.
 
i don't have a programmer. do you know anyone that does and can burn new ones for this game??
thanks
 
where or what should i look for if i were to buy a eprom programmer?? is there any place to get the game software to program the chips with or is the information hit and miss for each game??
thanks
 
after the second reseating of the rom chips it improved the lines on the characters and i left the game on for the last hour and went and checked it and its back to the way it started as which is the attract screen problems and no game play screen problems with the graphics.
thanks
