If you can find a Seimitsu produced auto-fire circuit board or another 3rd-party one produced one, they work just fine. ^_~

Unfortunately, the Seimitsu auto-fire PCB is all sold out and not in production in anymore.

If you can acquire a cheap-ass NES Advantage joystick, it has the required "555" chip that is used for auto-fire purposes.

Some ace Japanese shmup players use such daisy-chained auto-fire boards or a PC setup to fine tune such customized auto-fire rates for WR scores on PCBs and console games. Using an external auto-fire PCB will definitely save 'n' tear on the ol' hands and breathe new life into those old-school arcade shmup PCBs from the mid to late 1980's such as A-Jax/Typhoon, Alcon/Slap Fight, Darwin 4087, etc that didn't have auto-fire from the get-go.

Capcom's HyperDyne Sidearms PCB circa 1986, has a faster rate of auto-fire in-game than if you were to use such an external auto-fire PCB on it. That was a very interesting discovery to find myself. Capcom knew what it doing when developing Sidearms -- most mid to late 1980's arcade shmup PCBs didn't have auto-fire from the get-go.

I do recall playing on some USA region Centuri produced Time Pilot arcade cabinets that had auto-fire from the get-go and this was back 1984-1985. I'd have to assume that auto-fire was later added as a hack for it. ^_~

i was thinking of finding a cheap used hrap and just 'borrowing' the autofire setup....

i was going to try and use a saturn pad i have with autofire controls on the back but the autofire stuff is embedded on the pcb...im looking for something with wires so i can splice into it

Just place a Wanted post for an external Jamma auto-fire PCB in the Trading Station and see what comes your way. Granted, such an external Jamma auto-fire PCB is the easiest way to add auto-fire to your existing arcade PCBs without the need to wire up and soldier such auto-fire curcuits from other console joysticks and the like. You can select which arcade buttons to have auto-fire via dip switch settings for easy customization. It makes your arcade PCB hobby more enjoyable since all the hard work is already done for you. ^_~

good idea....i will give it a shot

I bought a Sega Master System rapid fire unit years ago, but I never got it to run. it needs power I think.

[emphatic]

This is by far the easiest/best solution:



You just put this between the your fire1 button and fire1 gnd cable (black cable on the picture) and then connect any of the blue ones to the gnd on the fire1 button and whatever other button you want. Each circuit can handle 2 buttons. My setup is p1 fire1 and p2 fire1 using just one circuit.

I got mine from a swedish forum (a guy who got these fairly cheap from Yahoo jp I think). I know that sven666 use this circuit as well, maybe he knows where to get one directly from Japan.

If you plan to use it with a J-Pac hooked up, this circuit is NOT recommended though. I broke my circuit somehow when the J-Pac was installed and had to buy another one. I payed about $30 for mine.

im not worried about using it with the JPAC cuz anything i would be running through the JPAC has the option to configure autofire

but ya...that looks like what im looking for....i certianly dont have the electrical knowledge to throw that together myself but would definitley be interested in buying one......or trading...whatever

thanx for the info guys

Seimitsu never made any. 'twas Sanwa.

Which leads us to...

This is by far the easiest/best solution:

Sanwa MGM-SS2

There are others like it, but this was the best since it included a mirror of button 1 (so you don't lose the charge shot).
The ultimate weapon for shooting games.

Unfortunately they stopped production three years ago, so it's likely going to be a bit more painful to track down.

You can just reroute any button to any other button so you don't lose the charge shot with a simple clam cable (dunno what they're called) http://www.hod-electronics.nl/shop.aspx?id=TS%201&t=NL
But yeah that sanwa pcb is awesome, but expensive.

[jonny5]

curses...i figured it would be costly

still open to ideas or offers on homemade contraptions.....only really need it for psikyo pcbs

Whoops, yeah it's Sanwa alrighty. My mistake there. Thanks oxtsu for straightening it all out. Yes, I do have one of those bad boy Sanwa auto-fire PCB for my own personal use. ^_~
