I've been looking for a solution for use of a lightgun on my Mame/Mister FPGA arcade, with 15Hz CRT, and it looks like the Gun4IR project is the best option currently.
I've purchased the DIY kit from RPGElectronics, and have watched the few videos I can find on youtube about how to put everything together. They seem to focus mainly on the IR/mouse control wiring, for which they seem very helpful.
However, I'm unclear on how to integrate the control buttons that come standard with the Guncon-2 (4 way D-pad on the back, reload button on the butt of the gun, and the various push buttons on the frame). Pre-mod, these controls integrate into the original Guncon PCB, which I assume gets tossed during the conversion process, and replaced with the Gun4IR Adruino and associated software.
If so, how do people still use the push buttons on their gun? Do these somehow integrate into the Adruino? Do they still retain the original Guncon PCB for directional keys, and just re-route the aim-control tasks to the Gun4IR side hardware? Or am I totally missing the point and need to be asking a different question? I appreciate any/all info (Apologies if this has been asked, I've been searching for an answer for a few days without luck).
