Hello, 
 
I've got an issue with my Atari CX2600GP (secam video output). When i cold start the console, I can play a game normally but after 2 or 3 minutes, the game just resets, and the selected game number continuously increases by itself, like if the "Game Select" switch was stuck. If I turn it off, and turn it on again, the game stays stuck with game number continuously increasing. I must wait one or two hours for the controls to work again for 2 or 3 minutes. I tried different controlers (CX40 - CX78, all working fine with others consoles) and different games but always stop working after a few minutes. Did someone already I'm wondering how could this happen. Is the RIOT Chip dying ? Thanks all for your help.

PS : Sorry for my bad english

That's likely the cause, in my opinion.

Ok thanks for the answer !

Another question : Is the following chip is a good replacement for RIOT 6532 ?

Yes. Should be a drop-in replacement if your console has socketed chips. If they're soldered, you'll have to remove the old chip and clean out the through-holes first. If that's the case, I suggest you install a socket before you replace the chip.

Some news !

Today i opened my Atari 2600 in order to change the RIOT chip. I was lucky because all chips were mounted on sockets. I just replaced the old C010750 with the brand new 6532 chip i ordered from eBay. The console now works like a charm ! Thank you all !
