Finally a complete interface that utilizes original guns!
(which is no longer in production and in limited supply :lol )

Yep!... Handy that isn't it :lol .... I guess if this was done 6 years ago when it first came about it would of been a different story.

There is at least a handful of members who will benefit from this I suppose.

It's a shame really because the setup is as an original arcade lightgun setup should be.
You never know though if BYOAC member, Purple Tophat, manages to get enough people together for a bulk order of these, then they may think about bringing them back into production :dunno

Great work figuring all that out. The "optigun" manual was almost completely worthless in terms of documenting the commands. I wonder if Foley wrote it himself? ;)

For the record mamehooker just uses a generic "hid write" function which can be done in vb and c almost as easily as writing to a file, so a dll could be written to support all those commands quite easily. That being said, considering the only person that ever wants to monkey with outputs and advanced scripting of outputs is me, I don't really see the point.

I'm glad to see the hid write function get some use. I added it because I got sick of people PMing every week to add support for their custom I/O board. Strangely enough when I added it and started replying that they could do it via the function they determined that it would take some actual work on their part and decided it wasn't worth it.

Funny how that works. ;)

Btw those auto recoil commands... you might want to play with those some more. It's really odd that the third byte is used for the duration so the second byte might enable looping, ect. My guess is with some tweaking of the settings you can get those to do a repeatable "machine gun" firing pattern as well. Or at least the optigun manual alluded to that.

Cheers Howard, you've made me realise I've left a command out of that list.

The manual recoil command does make the recoil fire repeatedly (like machine gun fire) while the trigger is held down in games like T2, Rev X, Operation Wolf etc.... I did notice the gun getting pretty warm after a while though using it like this.

The command I missed out adjusts the duration of the recoil;

Player 1 Manual Recoil (Recoil Duration 5):
ghd 1 &H1AB7 &H6570 8 &h04:&h01:&h05:&h00:&h00:&h00:&h00:&h00

The third byte, &h05 in the above command makes the recoil do a double tap. The duration between tap's ranges from &h02 (tap..tap) to &h09 (tap...........tap). &h01 is just a single tap.

Thanks again Howard, I'm sure they'll be other commands I come across.

Added a video of the completed project to the original first post :)
