Any idea if anyone’s done a writeup on how to mod a CPS Fighter stick with sanwa parts?


#87

Anyone know if the Seimitsu LS 32-01 has extra play in the stick? I’ve got an HRAP2 that I just put it in. The stock Sanwa was nice but I heard alot of things about the 32-01 that I figured I’d like, including a stiffer spring and a shorter throw. Well that’s all well and good but when I push the stick in a direction, after it hits the restrictor, the top part of the stick moves an 1/8th of an inch past where the restrictor is supposed to stop it. This is because of all the vertical play in the stick itself (you can pull it up and down just like Sanwa’s). The stick DOES stop at the restrictor but since of the vertical play, it moves up and over in the direction that I’m throwing it in. I don’t know if any of that makes sense, it’s hard to explain it. In any case, it kinda defeats the purpose of switching over to this stick since the throw ends up being the same as the Sanwa’s. Does anyone have that issue or do I have faulty equipment?

Taiki, the CPS Fighter Stick would be pretty odd to mod considering the stock buttons are small and close to each other. The stick is fairly thin and would be difficult to mount a stick. I haven’t even looked at mine that close because it doesn’t seem to be a reasonable stick to even attempt.

H82, I’m not really sure what you’re describing but I have never had a problem with the LS-32 moving past the restrictor. Most of the time, my shaft hits the metal base piece before it even has a chance to hit the plastic restrictor piece. I mean, yeah if you put a really strong force on any stick, it will have vertical play that will lift the stick out of it’s normal path. But if you’re doing that, then you’re just not playing correctly. : )

well, looks like I get the task of doing that write up then. :slight_smile: After seeing the mod of the NeoGeo old style home stick with Sanwas, I figured it was POSSIBLE…

I finally broke my CPS Fighter Stick apart and finding that there is more than enough space to fit screw in 24mm sanwas for the buttons and maybe an LS-32 for the stick. I prefer sanwa, so i’m going to try to shoehorn a JLF first


#90

Keep the stock stick, it’s Sanwa anyway.


#91

How do 24mm buttons compare with 30mm buttons? Is there any difference beyond size?


#92

They use the same kind of microswitch so there shouldn’t be any difference in performance.


#93

is it? I’d rather have a JLF in any case.


#94

It’s a Sanwa JLW.


#95

It’s not the JLW that Sanwa’s selling now. When I have a few spare minutes, I’ll take pics… Looks more like a Hori or even seimitsu…


#96

I could take pics too, it’s unmistakably a JLW with Sanwa written on it.


#97

Do you have a Japanese CPS Fighter?


#98

yes.


#99

that explains it.

Could you take photos of the internals if you’ve got the time/effort? I want to know how to mount a JLW in this thing and if it’s possible to mount a JLF in it’s stead.

That’s what mine looks like. I can’t find my camera for some reason, otherwise I’d take much more detailed pics of the mech assembly.

Basically, it looks like some sort of seimitsu mechanism with a blue and white base. I’ve never seen these before, but I’ve never worked with seimitsu parts before.

So they used a Sanwa stick only for the Japanese release… good to know.

Anyway here’s the pics:

The stick is screw mounted on the bottom shell and there’s even a hole for the shaft in case one wants to remove the ball:

The JLW restrictor is glued to the bottom:

I don’t think a JLW would be too difficult to mount on your stick, it would be just a matter of adding 4 spacers (of different height though) on the bottom shell. As for the JLF I don’t think you can mount one as neatly since they don’t have threaded inserts on the bottom like the JLW so you would have to drill holes on the top shell which is not even flat… can be done but it will not look very nice.


#101

Huh, this explains a lot. Looks like a JLW will drop right in… Since I already own a JLF stick(HRAP), I’m going to go with a JLW with a red bat top and some 24mm buttons. Although if i’m right, it’s already mostly a sanwa button because i think that’s a sanwa switch soldered to the board. In either case, time to hack for hacking’s sake.

thanks!

mind if i upload these pics to the Game SX/NFG Wiki for the CPS Fighter?


#102

Sure, you can use the pics.

The buttons have Tokaicom switches which is what Seimitsu uses for their buttons so even if they’re not Sanwa they’re still arcade quality switches:

These switches are also found on the Neo Geo old style stick, Namco PS1 arcade stick and all the HRAP buttons.


#103

i’m going to have to mangle the hole in the case.

Which means I have to either suck it up and break out the sharp objects, or just stick with the stock buttons. I’m honeslty not sure what I’ll do with the buttons.

However, with the stick, it’s a no brainer, I’m swapping in a JLW. Let’s hope this works.
