Re: SNES multitap schematic

For the moment, just investigating. I had this crazy idea to build a pair of them and combine it with my Micro NES board project (which I'm working on an SNES version of) and basically have 8 controllers all built into a single monolithic board... it'd be interesting to see what you could do with 96...

Re: SNES multitap schematic

I think I've hit pay dirt. Not only did I find the schematic in the OEM SNES developer's manual found here: http://www.romhacking.net/documents/226/ (book 2, page 387), but the chip appears to still be in active production by TI: http://www.ti.com/product/cd74hc4053 . Here's the full schematic: http...

Re: Planning for my first portable (N64)

Reserving for updates, and I'll post what I've done so far: I have a rev-03 mainboard, so I have access to RGB video, and I have 2x2Mb RAM chips on-board. I have removed them and plan to replace them with 2x4Mb chips directly on-board so I don't need an expansion pak at all (I know I need the termin...

Planning for my first portable (N64)

I'm currently putting together parts and plans to build an N64 portable this summer when I have more free time and a better workbench. I think I'll start throwing my plans down here and then once I start building, I can post updates once I have something to update. For now, I'm going to see what peo...

Re: 3rd Party NES USB controllers...

Ah, right... I was thinking of ones like http://www.retrousb.com/product_info.php?cPath=21&products_id=32 . I'm not sure what the knockoffs look like on the inside. I don't even know if they use squishies or tact switches. In any case, they probably use gloptop IC's, if that's what you're wondering.

Re: 3rd Party NES USB controllers...

Most of the ones I've seen use the original controller's PCB, then wire a converter circuit into the controller's output pads and the USB cable comes out from there, but it's probably different for each one. If you want to know about a specific one, you'll have to provide more details.

Re: Problems with a snes controller build

A difference of .6ohm isn't likely to cause issues... You do have all of your grounds connected to the brown controller wire, right? Some things to mention, pin 11 on the second IC doesn't matter, it can be GND, +5v, or disconnected entirely. Also, I don't believe you actually need separate resistor...

Re: DMG Gameboy Ribbon Cable

I think I have the measurements (at least fairly close) but can anyone tell me what this type of ribbon-cable connection is called? Searching Google (or distributors' websites) for "ribbon cable connectors" tends to come up with IDC connectors, which this obviously is not.

SNES multitap schematic

Does anybody have a schematic for the SNES multitap? I've looked online, and all I could come up with was the schematic for the Naki TribalTap here http://www.neviksti.com/wiki/TribalTap#IC_Chip but that same page indicates that it does not follow the official spec and would not be detected properly...

Re: Problems with a snes controller build

Have you tried testing it the way I suggested, just shorting the IC pins to ground on your protoboard? Take it one step at a time, starting with getting the controller circuit itself working, then wiring in actual buttons. That way you can isolate the issue. Also, double/triple check the 5 wires goi...

Re: DMG multi-mod

If I ever get this all done, I plan to actually order a professional PCB, but for now, I'm having fun making my own... It makes things like hooking up the Game Boy cart connector to a breadboard a lot easier. It also allows me to break out those QFP USB chips to a breadboard, which would have been a...

Re: NESp controller?? (HELP)

Just to throw this out there... you don't actually need to sacrifice an NES controller for the IC. You can still buy CD4021 shift register IC's brand-new. Jameco has them as cheap as $0.39 each (+shipping) http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_12829_-1 . Also, if you're...

Re: Problems with a snes controller build

What I'm saying isn't a matter of shorts, I want to know what the internal circuitry of the joystick is and how you are interfacing it into the 4021's to know if it's even compatible with hooking up to an SNES in the way you are attempting.

Re: Problems with a snes controller build

I have a feeling that the issue is in how you are connecting to the joystick. Mind posting pictures of those connections? Also, to test your perfboard setup, install the IC's and resistors and then just hook up the wires to the SNES connector (connecting them properly to both IC's), then you can tes...
