Looks like all the sprites/graphics are messed up it looks like everything moves around correctly but no graphics....

What do you galaga gurus think? This was a totally trashed game falling all apart before I got it and did work at all so this is the first power up after rebuild. I cleanup the board, checksum all the roms and the video ones were correct. Some of the CPU ones were wrong so I burnt 6 new ones for the CPU.

Here's what I'm getting:

Update I read another post about blocky graphics so I removed the 02XX and 05XX chip on the video board in the rom with the roms and of course a couple legs broke off.... so now I'm further behind. I on purpose did want to touch those chips. So I guess I have to replace those sockets as the pin is still in there and solder a socket on the 2 chips that broke. Maybe the 02XX once fixed will be it. Its helped someone else so maybe!
 
02xx or the color PROM. Never touch the 05xx. Legs are too fragile to f*** with.
 
You can break off legs from a donor chip then solder them onto the old stumps to fix the chips back up. If the legs broke off flush with the plastic then you gently dremel away enough of the plastic to make a solder point for a donor leg.

Confirmed. I've done this on a surface mount transistor even. It works.
