I'm using baseball as my donor cart for Balloon Fight but its not working. I burned bf's prg file to a 27C512 and stuck it in the socket then I got treeted to a nice gray screen. I checked the solder by sticking the baseball rom back in and it worked. Then I dumped the baseball prg chip, erased the 27c512 (erasable winbond ), burned it, verified it, loaded it then marveled at gray. From what I've read the pin outs are the same for 27c512's and 32k prg chips. What am I doing wrong?
Thanks
