I have been working on several of the Operation Wolf boars for some time and have run into several problems with program files.

I had one that was working but had some vertical lines running through the images (looked like bad ram). I don't have spare rams to test so I pulled the roms and check them. Two were blank but instead of the correct blank code it had BF all through the rom chips (Yes two were like that). I erase the chips and programed the correct code from my working board set. Now the board does nothing!

Are these roms encrypted and does someone know if the blank roms are for filling the address in the program.

I would like to get this board set back to running condition. All socked chips have been tested and working. Voltage is fine and have a working cab to test in with a working board set.

I believe the rom changes I did stopped this board from working and need some indications on where to go from here.
 
are all the roms on the good place on the mainboard ??
no legs bent ,is the eprom far enough pressed in the socket
have checked of the mark/key from the eprom is on the right place

double check the roms for the right program( verify ) otherwise .... erease them en burn them again at slow speed this time with software from mame maybe it will helps

Oh yes!

I had the board set working but the roms looked like they had bits of program missing. I burned a new set from a working board and now I have nothing.

I have heard a rumor that the roms are encrypted and wonder if that is true or not.

I do know that if you take the roms and zip them for running on mame they will have the final scene on the jungle missing. The part with the hostage and final Rufkin.

Voltage and legs are fine I firmly believe it is in the program it's self.
 
if you want the roms, i can make a copy and send it to you !!!

but i think thats the roms are not complete empty when you burn them
so try to erease them again ,and burn it again at slow speed
 
and have you got it working again ??

Got the rom files and still nothing at all. I put it up for awhile but have to measure a wire for another member so I will put in the working board set to measure it.

Thank again for the rom files.
