Famicom Powerpak 47K resistor mod with switch FDS extra sound in games

With this mod you can enhance the sound of certain famicom games when using the powerpak.
some japan released games like doki doki panic and zelda's sword sound can be heard using
this mod to the NES and some files added to powerpak directory. You have two methods in this video (1) just adding a 47k resistor to pin 3 and 9 of expansion connector always on. method (2) adding a switch and mounting the resistor circuit on the underside of NES with hidden cover and ON and OFF switch. VISIT nesdev.parodius.com for Loopy's files download and directions on powerpak file setup.

why a momentary? cant the switch be an spst thats not momentaery

[alienform]

@YoshiFan501

any switch will work . you dont really need the switch but its great if you want to compare with the resistor and without...

[cavemano123]

if i were to do the first method, the one not including the on/off switch, would that effect games that dont support fds sound in anyway?

[alienform]

@cavemano123

no not at all. no effect switch is only for comparing with and without

[alienform]

You can mount resistor to removable plastic cover on bottom of NES sometimes the fit is tight when you cover the expansion connector port. leave wires longer and mounted to the inside of removable plastic cover on bottom of NES. Or anywere you like as long as the expansion connector on motherboard sits in the bottom cavity of plastic case.

stupid nintendo being so coriouse NOT to put the external soundpins in the cartride port of the nes,besides the exp port,and stupid enough to even refuse company's the bring their own specialized chips to the west,as sadly as it is,the west versions dit,nt exist or were slichtly downgraded.

i know that nintendo intendo a disk system for the nes either too,but since the insucces of it in japan,it never reached the west.

their early plans just turned into a wastle,aaarrrrgggg nintendo!!!!!!!!!!

@cyhill99 You only need the switch if you wanna make comparison videos. There's never a situation in which you need to disconnect the resistor for the NES to function properly. Just solder a 47k resistor between pins 3 & 9 of the expansion port and call it a day. No need to cut up the NES casing. It's so simple that I went ahead and did the mod when I opened up my NES to clean the 72 pin connector and disable the 10 nes chip. I don't have a powerpak yet, but my NES is ready for it :p .

@XMaskedMagicianFanX Not possible without major hacking.

[cyhill99]

is there any real need for the switch?

[mexicanwaluigi]

really good vid thanks for sharing, I had seen ways of doing it with out the switch, but this is the first switch i've seen for it. You could always just use a second nes to compare if you don't want a switch. :D

So wait, the American NES is actually capable of playing back ALL the sounds in the Famicom/NES library? The expansion port on the bottom was an unused sound module of sorts? This is incredibly awesome, sir! I also have a video request in addition to my questions: would you ever consider making a tutorial for the Super NES digital audio mod (I can give you a link if you want). I would love to see how an experienced console "modder" would go about doing that particular mod...thank you so much!!!!

Cool, but dude, putting that single resistor on a board and have it glued to the case was totally unnescessary. You could have just soldered the resistor directly to one end of the button and put some electric tape over it. Less destructive that way. :)

Method 3 (or 1.5): 1. Solder a length of wire to each end of resistor. 2. Slide heat-shrink tubing over end of wire to cover resistor & soldered ends. 3. Heat the tubing. 4. Solder to appropriate point(s), adding in switch (and third length of wire) as detailed in video.

You *could* even run the switch wires out the expansion cover clip holes if, like me, you can't stand the idea of cutting on your precious NES case.  :)

[qwerfderf]

so with this mod i can play .nsf files containing expansion chip channels?? if true im a verry verrry happy man :)

so you dont need expansion chips because they are flashed through the powerpak?????? This is very confusing due to the lack of physical components as if the console can emulate these sounds.

@captainnintendo no, you need a soldering iron.
