Absolute Question and Answer Thread v.3 (ASK YOUR QUESTIONS HERE!)

The levers on the switches are bent, so the engage and throw feels the same.
Probability easier to bend all the levers on the switches than to make new plastic molds or get a custom sku for the switches.

Need some help. Bought a UDUSB and an MC Cthulhu, also have a Genesis pad I want to pad hack. Does anyone know if any of the consoles supported on the MC Cthulhu or the Genesis will give any hiccups with power requirements for the 2 PCBs and the stick and if so how do I go about adding power to it as a back up measure? (Like an external power supply or a 9v battery ?)

Might be an idea to do a project box stick for that one?

That’s what the undamned usb decoder is for essentially.

Seems the MD pads run on 5V (and use weird multiplexer voodoo to drive the pads since there aren’t enough pins to read inputs. I’ve anecdotally heard that the MC Cthulhu runs at 5V even when it’s not the voltage of the console (I.E Dreamcast).

How do people plug holes where cables used to rest in fightsticks? Going to be modding a RAP clone soon and I want a Neutrik. What I don’t want is for dust and shit to enter the stick via the cutout where the cable used to sit. Any standard stoppers people can recommend to fill that hole in?

I’ll have to do some testing on this when I get them both in. Have to order some extension cables and hunt down some insructables to make the rj45 cords for the MCC. I bought a couple Recipe card boxes for like $1.50 each at goodwill that I thought would be pretty nice for project boxes. The first thing I’m probably going to try after update on both PCBs is going to be to see if my Razer Atrox (XBONE) works with the ps3 (since cthulhu has ps3 support), if it doesn’t I’ll try the Madcatz Xbox 360 fight pad to have as a placeholder or I can test it via the redundant way and use my madcatz se ps3 to ps3 via pass through the pcbs (should test it accurately in theary). Then after testing the new Genesis Controller I bought for all functions I’m going to pad back it and test it with the udusb and stick. Hopefully it works out so I can use my MK9 TE stick on MK1-3 and use my Madcatz SE on SF2T and Primal Rage

JB weld perhaps?

I was thinking Sculpty, but I’d ideally like to avoid permanently modifying the case as much as possible (I’m already going to have to make four holes in the back for my DPDT and lock switches, share button hole and Neutrik, but those should look clean with a decent hole saw).

The Wireless NES-looking stick for the Switch comes with a rubber stopper. I was wondering if it was a standard part.

The PlayStation 1 and 2 puts out 3.5v, and the MC Cthulhu works on the PlayStations, so that debunks that theory.

The Genesis /Megadrive pads Encoder works on a Multiplexer. All the Pins are direct inputs except for power, ground, and a sense line. The Pad is polled twice and using the sense line the console knows is it the first or second polling, and the additional inputs are read the second time along.

DB9 Pin Select is low Select is high
1 Up Up
2 Down Down
3 Ground Left
4 Ground Right
5 Control: +5V
6 A B
7 Control: Select
8 Control: Ground
9 Start C

This is done so the Genesis is backwards compatible with the Master system and other DB9 Consoles.
Its why a genesis pad works with an Atari 2600.

Now for the 6 Button pads, the controller is polled 4 times, The 3rd time is for the new additional inputs and nothing is read on the fourth. Basically they Multiplex the Multiplex.

The TG16 Game pads, the two, three and Six button pads work in a similar way to the genesis

Yeah, and the Dreamcast puts out 3.5 while the MCC pulls 5V, someone on he shmups forum was concerned it might cause damage to the console

Where would it pull 5volts from? The MC Cthlhu don’t have a dc to dc converter.

I got to recheck but I am sure the DC does 5volts.

A lot of good info in this thread: the DC does run a 5V line to the pad, which then drops it down to 3.5V. The MCC keeps running at 5V, which I’d seen another poster suggest might cause damage and is part of why I bought the Brook converter: https://shmups.system11.org/viewtopic.php?f=6&t=41051

I played sf2 hyper fighting on a american cabinet recently and had real problems hitting diagonals. I’d like to know if this is normal or the switches are dying. I have one of those 5 dollars an hour 10 dollars for the whole day arcades with old 80’s 90’s games near me. Thanks.

In the past it was probilly intentional.
Arcade owners used to use subpar or inferior parts so players played worst and used more quarters.

As for today?
American parts are designed for durability and not precision.

So do I need a special setup to use the genesis or mcc to use it with the udusb? I’m not trying to mess up the consoles or the pcbs.

Undammed USB decoder to genesis? No.

How about the MCC and its many consoles?

They all will work fine with the Undammed decoder. The Undammed just need a steady 5 volts.

Okay. So in case I need to add more voltage should I add like a external power supply or like a 9v with a resistor of some type? I’m basically making an EVERYTHING converter box. Sorry about the thousand questions x.x
