Rapido : Autofire for Superguns and Jamma Cabs

[bencao74]

Rapido - Auto Fire Project for SuperGuns and Cabs



I was asked to make a PCB for an autofire project.



Features :

• For Neo Geo Compatible Controller

• Easy installation, just plug between controller and supergun

• Supports 4 Buttons and 4 different Auto Fire speeds

• Configuration via Game Controller, no need of extra buttons

• LED for configuration visualization

The autofire has own MCU implementation and is configured by the controller itself.

Configuration Howto

1. Press Start Player 1 and Button A -> Rapido is in config mode
2. Press Button A one time -> First level auto fire speed. Press Button A up to 4 times for four level of auto fire speed
3. Repeat this for Button B, C, D if wanted.
4. Close config Mode with pressing Start Player 1.

All configuration button press will be visualized by a LED.

The implementation is finished and prototypes was successfully tested.

Here`s a video of this little friend in action. It`s like an adapter.

Next steps will be the PCB layout plus enclosure work. I want to make one supergun / neo geo compatible controller version at least.

Question left is to make a Jamma version or not. What do you think?

[emphatic]

Voting didn't work. I voted JAMMA version. Will this be able to clone button 1 to say, button 3 or 4 for games with charge attacks?

[trap15]

emphatic said everything I was going to say.

[bencao74]

I`ve deleted the poll and take a look later to that. The poll was

Supergun Neo Geo Controller Version
Jamma Plug and Play Version
Both
Autofire is cheating

Will this be able to clone button 1 to say, button 3 or 4 for games with charge attacks?

Could you explain in more detail?

[trap15]

Like, you set it up so that pressing button 3 acts like a rapid fire of button 1.

[bencao74]

we`ve to think about a way of easy configuration then, because we wanted to avoid using a display or something. Further we`ve to check the place left on the MCU. We take it into consideration. It´s a reasonable feature

[Ghegs]

Very cool idea. I have a similar device for NES and PS2.

I say a JAMMA adapter is the only real way to do it, because otherwise you cannot tap the CSYNC line
for implementing SYNC rapid fire which is synchronized to the actual game VSYNC for maximum and consistent rapid fire rate.
I'm assuming that the circuit you're using assumes a 60HZ refresh rate?

Also, I don't wire +5V on my 15 pin joystick port because I use the pin for kick harness buttons.
A in-line joystick port adapter will not work in this case.

[cools]

Adjustable synced auto and button remapping and I'll buy a couple of JAMMA ones.

For the supergun version custom pinouts are not supported of course, only the standard neo geo ones.

So far four different speeds are implemented. Taking the Vsync into account should be possible for the jamma version. Since the jamma is todo I put it on the feature request list.

Such posts helps me to calculate the project! Thanks a lot!

Please make a JAMMA version!

Is there anything you can do to make it work for games like Strikers so you can have one button for autofire and another one for charge shots?

[bencao74]

for the supergun version it will only a simple design without button mapping / cloning. For the jamma version we will enhance the design. At least we`ll give it a try. The supergun version PCB work is done and about ready to order.

For the jamma one we`re considering

- Button Mapping

- Configuration Visulization

- perhaps USB connection. Dunno, perhaps a bootloader. I`ve been thinking about configuration management with a windows app.

- Synced Autofire : It`s really not difficult to implement. Up to now we`ve implemented asynchron autofire and it seemed quite ok for us. Sure, with asynchronous autofire one frame could be missed. Anyway, we made a little study and gave Rapido to gamers and configured the auto fire with 10Hz asynchronous. There was no complaints and this was only on shoot every six frames. The delay discussion is always difficult since human cognition can be trained below 6 frame for sure But which games need 1 frame accurate fire rate? Could someone give me examples or gaming situations?

[ikaruga007]

Will definitely get the jamma version.

[bencao74]

Hey,

just got the PCB and assembled the first one.

Next step is to test this little friend.

This autofire PCB will be great in combination with my new take on the Supergun MAK strike project. Here is a little teaser.

I'm not 100% certain, but I believe Fantasy Zone and Raiden DX (both games which I'd want to use with this device) have frame accurate fire rate. Blazing Star I believe is another one.

I know this is an ancient thread...but I am hunting for one of these and coming up dry. Anyone know where I can find one?

Have one. I need this for a CMVS.
