Arcade Supergun A51099 (Vogatek) sega megadrive controller chips

[Matt-MCJDesign]

Hello, I have recently brought a Vogatek Arcade Supergun (Model A51099). The megadrive controller IC's for the unit did not work how I wanted.

 The problems for me were.....
1: If no controller is plugged into port 2 then random switch inputs occur (documented on the paperwork that came with it...... I only have one controller!)
2: Not being able to "add a coin/credit" without getting up from my seat to press the button on the PCB

 I wrote my own software for the PIC16F505 chips, and it works very nicely....... The random switch inputs are sorted by having to press "A" on the megadrive controller when first powered up. The "add a coin/credit" works by holding "Start" and then pressing "C" to add a coin/credit (2 wires have to be soldered on the underside of the PCB to make this work, very easy mod).

 Basically, I am new to this forum, and wondered if this code would be of use to anyone else? It seems a shame to only use the time and effort it took on just one Supergun!

 If you are not sure what the I am on about then here is a link to a description of the device.

 I am offering these files for FREE, as long as they are not used for commercial gain, if you want to sell them, then please contact me and I we can talk!! All rights to the software remain with me (MCJ Design)! These files are all my own work and are not ripped/reversed engineered from the Vogatek chips.

 Please note, I do NOT work for, am NOT associated with and make NO money from Vogatek!
 OK rant over

 Let me know! (also I am not sure how to attach files... duh... sorry)

Regards


MATT!

Hello, again I have worked out (I think!) how to attach a file

 This hex file is for the Vogatek A51099 Arcade Supergun. It is to replace the existing code on the 2 PIC16F505 chips that are on the PCB. You will need a PIC programmer to update this (you can use the original chips as they are flash parts).

 When initially powering the supergun you will need to press "A" before any keys are recognised (you only need to do this once). This will prevent any random key inputs if you do not have a 2nd controller connected.

 Press "Start" and "C" to add coin/credits, you will need to do the wiring mod as shown in the attached picture to use this feature.

 Please note, this file is supplied "as-is" use it at your own risk!

 Have fun, please give me some feedback if you find this file usefull!

 Thanks



 Regards


MATT!
