Modding a Mayflash stick (finished! 1/18/2009)

ah, ic thanks ^_^.

now comes the internal debate of whether or not to file up 30mm or to shell out $$ for 28mm international shipping.

Im quite tight on money so i would probably end up drilling :slight_smile:

mmm so many decisions.

i’ll most likely wait until the Stock mayflash starts breaking down before i mod it, though i will probably have the parts in storage before then.

This is all in anticipation for the PC SFIV =P i dont have a PS3/XBOX so i rely on the small ammount of time that i get to bum off a friend.

On a side note, i believe i read somewhere that Chinatown Fair uses Sanwa parts. although thier Joystick feels like crap when im using it playing Guile. Is this most likely the result of constant use or something else?

because if the Sanwa stick feels that loose i might go with Seimitsu because i heard their stick was slightly stiffer but still jsut as responsive. I didnt like HAPP sticks, most likely because i rarely played on those O_o

You don’t have to order internationally for 28mm buttons: like it was said they are OBSF-24’s/OBSN-24’s: you can buy those from places in the US like lizardlick or modchipman

But please dont get the OBSF-24s/28mms: they’ll just drop right through your top button holes:shake: you want OBSF/OBSN-30’s for this mod

When djchen011032 say 28mm, he doesn’t mean the Sanwa OBSF-24 like previously mistaken by him.
He was confused because Coinop Express described Sanwa OBSF-24 as 28mm.
Which is totally true, the diameter of Rim is 28mm.
But when we talk about Button size; 18mm, 20mm, 24mm, 30mm; we are referring to the size of hole Button goes into.

By saying pay for International, is mean buy the Crown Buttons, which are Korean and use 28mm holes.
Would be buying from laugh, SRK Member in Korea.

Holes of Mayflash Case are 28mm.

Alright, i think i got the gist of it.

Heres a list of potential parts im going to collect together when i decide to mod i suppose.

Stick
**Sanwa JLF-TP-8T **(Comes with Harness)
-As stated by another thread, it would be best to file around the stock peice and undermount it, i think ill go with that.

Buttons
Crown 203A(Quick Disconnectable)
-AS i dont want to file any more then i need to, the 28mm will be my best bet on the mayflash i suppose.

Board
I’ll stick with Stock until it breaks down…
On stock…
R1 R2 BU BR BL BD L2 L1 GND

With a weird funky button layout…

L2 R2 L1 R1
O /\ X []

what kinda crack were they on??
If anything i’ll just match it up. Still need a clear description of which is the ground wire.
I read Red, Black, or the first on the right. quite confusing.

**Cthulhu PC/PS3 Board **
For 50 dollars and no soldering required, looks to be a heavy price that i cant pay yet. Though offers the functionability that Stock PCB cant offer. I’ll Look into it.
On the Cthulhu…
PS3:
1P: Square
2P: Triangle
3P: R1
4P: L1
1K: X
2K: Circle
3K: R2
4K: L2
Start: Start
Select: Select
Home: PS

BTW, you said 18mm will fit intot he small 4 on top of the mayflash?

Factoring in All the Costs it ended up being $150. Lol same as a Stock TE stick. at least i hope ill get the satisfaction of building a stick myself when the time comes.

Running Through…
Just trying to set this up in my head since the MAyflash wont arrive until July7, the same day i get SFIV for Pc. heh.

First to clear a question… What gauge wires should i be purchasing for rewiring the Board to Buttons? I noticed that they are directly mounted to a Button Board, and that the first poster used “Too Thick Wiring”

Going to be Based On Stock Board… (Sorry For Repeats but I prefer to consolidate…)

Joystick - Sanwa JLF-TP-8T (Comes with Harness)
I need to keep in mind the color code as posted in the first.
Pretty much i need to match up with what the Stock part was soldered to.

1 - Black - ground
2 - Green - Left
3 - Yellow - Right
4 - Orange - Down
5 - Red - Up

Buttons - Crown 203A for the 8 Face Buttons.
These are happy 28mm that will fit without modding the Mayflash if my information is correct.
They can quick Disconnect as well, which makes things even simpler.

Thats it if i wanted to Use Stock PCB.

With Cthulhu I have more options…
-Which would mean… No top 4 buttons.

Which means i need to purchase… 3x 18mm Sanwa buttons to replaced, since those top 4 are soldered directly to the stock pcb if im not mistaken. That means i need even more wire and QD attachments. But i get Start, Select, and HOME out of this trade.

Although now with the Cthulhu i dont have to solder any thing. thanks toodles.^_^.
Soldering Kit is $30. Pretty much at $40 a board i save time and effort and money…

PS3:
1P: Square
2P: Triangle
3P: R1
4P: L1
1K: X
2K: Circle
3K: R2
4K: L2
Start: Start
Select: Select
Home: PS

Thats the Boards Layout.

Total Costs goes into $150 as last posted =P wonder what im going to do now.

The colored wires on Sanwa JLF-H (Wire Harness) does not dictate the directions.
It is the orientation of the Sanwa Joystick that will determine which Microswitch does what direction.

So if you doing:
Black = ground
Green = Left
Yellow = Right
Orange = Down
Red = Up

Then you will be having the TP-MA (Microswitch PCB Assembly) with the connector oriented to the left.
And then just take the corresponding wires and make go to respective wire of Mayflash PCB or Cthulhu or Terminal Strip.

pretty much when i get the stick delivered, i take a look and match it up right?

But the JLF comes with a standard wire harness, that i can just plug into the joystick no? that should make it easier for me to match up the crimp/solder points then

I’ve been looking around stores and the only wires i could find were…

22 Gauge speaker wires are abundant in Radio Shack as well… Will that work?

or do i need a single-core cable or what not?

i’ve done it with 24 gauge awg hookup wire stranded from radio shack: btw this information is everywhere on srk if you just use the search

Yeah, i pulled up a jameco Electronics Online store instead =P

@djchen011032: Forums have this amazing thing called an edit button you should check it out. Double and Triple post might also be against forum rules so you should check them out too.

Not much on the matter of Double/ Triple posting, if you’ve noticed the time difference between each post, it is within exceptable posting limits.

10:01 of Yesterday, 1:20AM today, 1:40AM today, and 2:13 right now.

Unfortunately for all the good the search button is, its not pinpoint accurate so there is some ammount of digging, and in the process dropping a line in the case someone like your fine self could pick up and readily provide much needed assistance, while continuing to browse through the forum posts for any information i may seek. Yes there is an amazing EDIT button as you so mention, but it doesnt quite work well in terms of a conversation when you backpost, expecting someone to read your post when they have already bounced a post foward.

meanwhile my little endeavor has gathered me some much needed information regarding purchase locations, as well as debatable choices that i probably wouldnt have found else where.

www.jamesco.com - finally found a decent site that sold 100ft bundles of 22gauge cables for $4.95

If this particular information was EVERYWHERE in the forums it shouldve taken me those 300 seconds to find a “Best Match for Your Search” but that was not so. You know the rest of this sob story because everyone before me has done it and suceeded without the sarcastic remarks of board members striknig you from every post. Went through every single post lined up in the search queue until one that flashed in bright blue hyperlink text.

www.cableorganizer.com - what better way to organize your haphazard first-time modification to give it that professional yet also hassle free look? I do it with my computer rig and its no surprise that i would like to apply the same idea to an arcade stick that i look foward to modding! AS far as my pitiful attempt to search this forum has revealed, there hasnt been much in the case of organizing your wireworks besides zipties, velcro or electrical tape, Which by all means works just fine. BUT, is not astethically pleasing.

On the other hand lizardlicks is pretty much wide spread so that took a mere 10 seconds, thanks to the search function. But wait. isnt that a widely searched for topic? i think so. along with how to assemble a cthulhu board and how to mod for beginners those searches turned up quite fast.

Thus, do me a favor, and dont treat me like some unsavory piece you just steppped on the sidewalk. A single line with the right wording can really show what the writer was thinking at the precise instant it was posted. You mustve had a bad day.

On another note, im concerned on why jdm714 has been banned. i know its not my place to ask but hes been nothing but help in this thread to me, along with a handful of others that have openly provided friendly and helpful aid.

ALSO. i would love to know how your grounding scheme works

Im looking over it and i cant tell head to to about it. I read over brokenhalos modification thread on
http://shmups.system11.org/viewtopic.php?t=22837

but im still rather clueless on where the grounds for the buttons are going.

There was also an included picture on the underside of the PCB but the only mention is unmarked is common ground.

is it those white round parts then? i can just shove allt he grounds in there or if i figure out daisy chain solder it down there?

Daisy-chain all the Ground of your Buttons together.
It does not matter which prong is Signal or Ground.

After Daisy-chaining all the Ground of your Buttons, you will have one wire leading out right?
This Ground wire will go to the Ground point on Mayflash PCB.

Remember how the Mayflash PCB has the labeled row of contacts?
R1 R2 BU BR BL BD L2 L1 GND

That is where you will have Buttons go to.
Signal of each Button will go to the respective Signal point.
The Daisy-chained Ground wire will go to Ground point.

Here are pictures to better illustrate:

Black wire is the Ground for Buttons.

http://img172.imageshack.us/img172/6686/mayflashdiagram.jpg

See the Daisy-chain for Ground?
(Ignore the Joystick part, person who originally drew just labeled for convenience, not correctness.)
(It actually goes: LEFT, DOWN, RIGHT, UP.)
(Do not follow the wiring of Buttons to Mayflash PCB either, just showing you where Ground is.)

Here is together.

You can even use the same Button Ground point for your Joystick.
But I like separating Buttons from Joystick.

I typed this Post, but I didn’t even know if I answered your question.
Laugh.

So, you not going the Cthulhu route?

Also keep in mind that if you wire to the mayflash pcb you’ll need to check which version you have. You’ll either have the same button layout for ps2 and ps3 or different layouts for ps2 and ps3. It will be clearly shown on the back of your box and on the insert when you get the stick.

The 3rd pic jdm posted is a stick with the different ps2 and ps3 layout. I forget the exact layout I used but I still have it written down if you need it.

excellence, thats the info i needed =O
Would the button layout matter if i was planning to rewire new buttons in? i know there was a post somewhere that mentioned the labeling

R1 R2 BU BR BL BD L2 L1 GND
Via this, its supposed to be written on the board if im correct.

To Jdm,

Im going to go with Mayflash PCB first, before i try my hands with a Cthulhu Board, since it is more expensive.

Besides, if i wanted to mount a Cthulhu board, it would require more work since i have to mount a USB.f into the side of the Case, since the PCB wont fit in the same location as the MayFlash.
That definitely helps.

Ive already begun collecting tools neccessary, drop a post if something seems missing.

*Edit: I figured id go ahead and redo the button configs, since i’ll be sticking with the stock PCB for a while. My plan is to remove the AUTO/CLEAR buttons and cover them up, leaving start/select as the 2 18mm buttons.
Rather then 8 button config ill stick with a 6 button basic, more art so to say and i just cant seem to get used to the sloping buttons (I printed out a blank copy and was mindlessly tapping at it) its awkward. After grabbing a mapout of the buttons for the Stock pcb, i think its in my best interest to swap the buttons and rewire the PCB as soon as possible. its some stupidly mind boggling controls. Guile FTW

EDIT2: Forget the 6 button config, after playing around in CF for a couple hours i kinda wished they had the 3P and 3K button avbailable… heh.

Reason being for the Cthulhu going into storage…
If and hopefully this mod project goes well, i’ll start fresh with a case i’ll build myself or purchase depending on what would be simpler, you know, like a no strings attached custom stick. All i have to do from that point is to just take apart the mayflash when the time comes. OR purchase new Stick+buttons if budget allows.

anybody have this problem? I haven’t used my mayflash since i modded it ages ago, then today i was doing some work on the acrylic and what not, all of a sudden, none of my punches work, the buttons work, because when i moved the kick wire to them it worked, but none of the punches, square, triangle and R1 worked… really really strange, its always worked, just dunno whats happening lately…

i’ll re-wire and re-solder the pcb when i can, but i just thought of asking just in case someone else that problem

Just Finished getting Everything in order, Wont beable to start modding until maybe 2~3weeks from now, Lizardlicks wont ship until maybe 2 weeks from today so i have to wait on that.

Mayflash will arrive July 9th, Crowns maybe right before the joystick/PCB+Connectors.

Heh, didnt hink it would be this time consuming.

@mR_caESaR

this does happen alot in networking, but im not sure if it will apply to your modded stick.

Normally, it would be a wiring problem but if after you try resoldering/Replacing wires and it still doesnt work, check your board for damages/obstructions on your PCB face.

maybe check your ground wire, if one part of the wire daisy chain isnt connected, the rest of the buttons (after where the ground is disconnected) dont respond till the ground is hooked up properly
