I did lots of mods and electronics projects, going back to when I was a kid.
I probably couldn't create one if I wanted to, but I liked following guides or assembling kits or repairing things that most would just trash.
A few years ago I seemed to have switched to collecting projects to complete, as opposed to completing projects. Yep.
Although a repair will get done because it is fast, rewarding, and easier for me than disposing and buying new.
That said, I did enjoy modding one of the "Tiny Arcade" games with the brilliant mod of using the 4 joystick positions at power up to select 1 of the 4 contained games.
Sure Pac-Man and Ms. Pac-Man are more iconic.... Okay! They had sold out of those 2 of the 4 released games.
I love the sound and artwork most on the Galaxian , and next the artwork on Space Invaders.
Why shouldn't I get to play Pac-Man and Ms. Pac-Man also?! Mizz Man - heh heh... hey, wait! My Aunt's name is Ann Mann, maybe she's related...?
Space Invaders was chosen to mod into a four game entertainment powerhouse.
Absolutely brilliant, I was saying, — No need for 4 jumper switches and 16 solder joints!
I liked that it can be done without dissembling entirely, just the screw to the battery door, then the back is just plastic snapped together with plastic tabs, then you see the electronics.
Four wires need soldered to 4 places on the ribbon cable that goes to the joystick.
The wires are already exposed between the circuit board and where the plastic of the "ribbon cable" starts.
Very quick, low heat, no desoldering, cutting or stripping of the games parts.
The following hundred words or so are my attempt to describe what should be a couple pictures.
The other end of the 4 wires get tack soldered; 3 to one side of surface mount jumpers. The 4th to a spot nearby shown in the post I followed. It had pictures. So much nicer than reading.
To supply my own 4 wires, I used a bit of old IDE cable from a box of computer parts.
I chose every 3rd wire to strip and tin. This held the perfect spacing of both the joystick ribbon cable connections and the 4 places the other ends get soldered onto.
Snap plastic back together. Insert batteries. Close back door and secure with screw, preferably the one you removed at the start of this mod.
To make a right angle from the ribbon cable I got tricky by using about a 4" length of IDE cable. Bending it 45 degrees from the 12 o'clock starting position to 3 o'clock, next taking the 3 o'clock end over itself to where the jumpers are.
This results in correctly spaced wires and a right angle.
Didn't get that? Another Example: "this letter: L turned 180 degrees clockwise"
Did I need to mention these things are fricken small?
I seemed to have lost a lot more readers upon mentioning "right angle".
No need to continue, as it is done. Really.
No more to do except marvel that you actually soldered four wires into that tiny space.

I know from talking on the side he was looking for Centipede and the other original atari flashback 7800 to NES NOAC conversion roms. I had them over a year ago but the site they came from when offline and I can't find another source.
