How To: Connect NES controller to Famicom

[133MHz]

Maybe if you don't get a close value, you could get away with a higher frequency crystal and binary/decimal frequency division using decade or binary counters.

what is this? difficult to do?
i have a 56 mhz one

56 MHz / 2 = 28 MHz . You can feed the clock output of that oscillator to a flip-flop or a binary counter to divide the frequency by 2.

For more information about these kinds of digital electronics, take a look here http://www.kpsec.freeuk.com/counting.htm

MCM Electronics don't have on their site

and if i buy a 30mhz one? http://www.webtronic.it/pages/ITA/prodotto.asp?ProdottoID=3642
i think are more easy to find at local shop. they cost 10 dollars? 

That's too expensive. But if you already have a 56MHz one the best idea is to use it. Buy some inexpensive binary counter IC or high-speed flip-flop and then you get your 28MHz.

ps. even a megadrive motorola m68000 is easily damageble from soldering? (made by tv repair shop that install modchip on ps1-ps2 not by me)

and the nes cpu? is the same?

I was referring to the crystal clock generators. I messed up a lot just by heating them a little too much by soldering! But yeah, take care with microprocessors too. Static discharge and leaky soldering irons are bad for them.

ok thanks 133mhz

62 replies ?! This thread spawns at least three different stories in one!: keiffer01's Broken Famicom and the Almighty PPU Swap, Arnold101's Quest for the Overclocking Crystal for his PAL CPU, satoshi_matrix's Quest for the Perfect Genesis Controller and some comments vaguely related with the original topic .

I wonder how CkRtech feels about it .

(my famicom still wait the cpu change, i have the pal cpu)

[satoshi_matrix]

lol my "quest for the holy genesis compatible famicon controller"

what an epic tale.

[Arnold101]

yehaa i have find the clock generator 4 pin 28.6mhz  in the shops is impossible to find, but a friend as shipped one to me 

and thursday i will receive the famicom with the pal nes cpu on it and i'll finish the mod with the clock

it's arrived the ntsc-pal converter too  (from november  )

[133MHz]

Nice!

I want to hear more about the PAL booster. Maybe you could write a small review, even for the site . I live in a NTSC country and I would like to know how well those things work, besides it would be a very useful guide for other people who want to play the Famicom on PAL TVs.

[Arnold101]

the ntsc to pal? ok 
tomorrow is the big day for my famicom

[Arnold101]

nada, same as before, gray screen  maybe is another problem and not the cpu

one question, i have used on famicom a master system adapter, that is 9v 500mA, and only today i have read that famicom need 10v 850mA  but with my 9v adpater the famicom worked well. but it can be the adapter the guilty of my broken famicom  a console can be damaged with a lower volt on adapter output?

[133MHz]

a console can be damaged with a lower volt on adapter output?

No, but reverse polarity can. Anyway a Master System is negative tip just like the Famicom so unless your adapter catastrophically failed or something it is not the culprit.

ok thanks
