I made a simple USB power box using a spare USB extension cable, a Sega Genesis/Megadrive joystick extension cable (DB9 plug end) and a plastic box which a Raspberry Pi came in years ago 😉
To make you own, all you need to do is use a USB socket (or cut one from a USB extension cable as I did), and connect the two outer VCC and GND pins on the socket to pins 7 (+5V) and 8 (GND) on the DB9 joystick extension cable. Add shrink tubing to the DB9 plug cable and solder the wires to the relevant pins on the USB socket.
Once you are happy with the soldered connections, shrink the shrink tubing to protect (or do as I did, cover in hot glue and hide your sins in a box 😉 )
Now, you must shave the end of the plastic plug to fit the Vectrex port and you are good to go!
Please note :
I do not accept any responsibility for damage to your Vectrex by using the USB power cable, use at your own risk!
The “AY 38912 Sound Tool” allows you to manipulate the AY sound chip registers.
Controls
Left/Right on joystick to select sound register.
Button 1 retriggers the hardware envelope.
Button 4 and joystick L/R to change values.
Button 3 changes values in steps of 10, Button 2 steps of 100.
You can save into 4 slots by holding down on the joystick and pressing button 1-4. You can load these slots by holding up on the joystick and pressing buttons 1-4 to recall.
As I didn’t have time to write any new Xmas themed games for 2016, I thought I’d make a little festive mod to one of my existing ones.
“Xmas Space Race” plays the same as the hidden 2 player game “Space Race“, found on my “Galaxy Wars : Space Launcher” cartridge. This version adds Christmas trees and a single player mode where you race against the Vectrex!
