FixBot & Trial

Hey Trial, ever tried turning a broken old gaming console into a retro arcade machine? I’ve got a few hacks that might surprise you.

I’ve dismantled enough consoles to know what works and what fails. If your hacks are based on solid wiring and component integrity, I’ll listen. If they’re just wishful tinkering, I’ll point out the risks. What’s your first step?

First, grab a solid board—an Arduino or ESP32 is the most forgiving, plus it’s cheap and you can stack it on the console’s PCB if you want. Cut out the power section and test the voltage rails with a multimeter, make sure you have a clean +5 V and a proper ground reference. Then solder a few jumper wires to the main controller pins you want to hook into. You’ll see which ones are live and which are dead before you even touch the console’s guts. That’s the only way to keep your wiring tidy and your parts from frying.
Trial
Sounds like a methodical approach, but remember to check the logic levels on those controller pins; if they’re 3.3 V on the console and you’re feeding a 5 V MCU, you’ll fry it. A simple level‑shift or a small resistor divider can save you a lot of headaches. Also keep a separate power supply for the MCU so the console’s regulator isn’t overloaded.

Good call on the level‑shift, you’ll keep that MCU alive. I usually wire up a 10k‑10k divider on the console’s 3.3 V lines and then feed that into the Arduino’s 5 V pins; if you need a bit more speed, grab a tiny TXB0104 from a Reddit post I saw last week. Keep the MCU’s 5 V on its own supply—just tap a clean 5 V rail from the console’s regulator, add a 100 µF capacitor close by, and you’ll avoid any regulator buzz. Don’t forget to tie the grounds together before you start soldering, or you’ll get a phantom current that burns everything. Trust me, that’s the trick that turns a half‑broken console into a full‑blown retro arcade.

That’s the right level of detail—just watch the capacitor’s ESR, a cheap one can ripple the regulator. And make sure the TXB0104’s reference pin is tied to the MCU ground; otherwise you’ll get shifting logic. After you’ve isolated the power, run a few loop tests on the pins before hooking up the display. That’s how you avoid a silent failure.
