Hello
I recently aquired a nice pirate famicom cartridge with lots of different games, but some of them had garbled graphics.. So I took the cartridge and preheated all the contacts on the back side. Some of the games are now working flawlessly, but not all of them. So I'm thinking that some of the ICs on the board are bad and need replacement. There is no problem replacing the 74 670, 74 174 or 74 273 but there is also a "programmable array IC" named PAL16L8 and I need help with it...
Is there a way to find out how is the array programmed? And if I know that, how can I programm such a device? I have a programmer http://www.elnec.com/products/device-pr ... prom-02alv but I'm not sure if this device can be programmed with it.
Here is a very bad scan of the cartridge:
Can anyone please help me with it? I was googling a bit but with no luck so far...
