Lastik & RetroBlitz | Character dialogue

Lastik

Hey, I was thinking we could try re‑building an old Atari joystick. I’ve got the parts, and it could be a good test for our DIY skills—plus it’d give you a legit retro controller to keep the 8‑bit vibe alive. What do you say?

RetroBlitz

Yeah, bring the parts, but no fancy LCDs or cloud services. We'll wire it up the old‑school way, hit the right pins, and keep the firmware simple enough to run on a 6502 in a jar. Just remember: no save‑scumming, just pure button‑tapping glory. Let's do it.

Lastik

Sounds good, I’ll grab the 74HC595, a few pull‑ups, and a stack of 10‑k resistors. We’ll wire the X and Y pins straight into the 6502’s I/O, use a simple scan routine, and keep the firmware short enough to fit in the spare 16‑byte EEPROM. No fancy LCDs, no cloud, just pure button‑tapping. Let’s get to it.

RetroBlitz

Great plan, just make sure those 10‑k pull‑ups actually pull up, not down. I’ll double‑check the register addresses while you solder, so we don’t end up with a half‑wired joystick that looks like a Tetris block. Remember: no cloud, no glitchy UI, just clean 8‑bit button pulses. Hit me with the parts list and we’ll boot it up in a single frame.

Here’s the kit: 1× 74HC595 shift register, 4× 10 kΩ pull‑ups, 2× 220 Ω series resistors for the buttons, a few jumper wires, and a flat 9‑pin IDC connector for the joystick. Grab a 6502 dev board with a 16‑byte EEPROM for the firmware. That’s it—no extras, no fuss. Let's keep it clean.

RetroBlitz

Got the kit, no extras, just the bare bones of a classic. Pull the 74HC595 into the data bus, latch the shift, scan the joystick once per frame. I’ll keep the firmware under 16 bytes—just a few lines of assembly, no loops that cause glitches. This is how we play: no UI, no cloud, just pure button‑tapping. Let’s hit the assembly line.

Lastik

Nice, lock the 74HC595 into the data bus, and keep the scan tight. I’ll wire up the buttons, make sure the pull‑ups are solid, and push the firmware to the EEPROM. Once that’s in place, we’ll have a clean 8‑bit button stream ready to go. Let's get it humming.

RetroBlitz

Alright, set the latch high, pull‑up those pins, push the firmware, then watch the 8‑bit stream go live. No lag, no UI—just clean button pulses. Let's see that joystick start the rhythm.
