When you're shopping for gaming replacement parts modding, the first question is usually which upgrade will change your retro setup the most. Here we have two entirely different projects: a digital HDMI mod for the original PlayStation and a USB-C rechargeable battery pack for the Nintendo Game Boy DMG-01. One is about getting a cleaner picture on a modern screen; the other is about keeping a handheld powered without a stack of AA batteries. They don't compete for the same slot in your collection, but they might compete for your next modding budget.
Quick verdict
If you want to improve how your PS1 looks on a modern TV and you're comfortable with a soldering iron, the PS1 Digital to Digital HDMI Mod Kit is the upgrade that changes the experience. If you play the original Game Boy DMG-01 more often and want to stop buying batteries, the RetroSix CleanJuice USB-C Rechargeable Battery Pack Mod Kit is the practical first mod. There's no overall winner because they serve different consoles, so the right pick comes down to which machine gets more play time.
At a glance
| Product | Price | What it does | Good for |
|---|---|---|---|
| PS1 Digital to Digital HDMI Mod Kit | $48.50 | Adds HDMI output with OSD, video modes, and aspect ratio controls | PS1 owners ready to solder |
| RetroSix CleanJuice USB-C Rechargeable Battery Pack Mod Kit | $35.00 | Replaces Game Boy DMG-01 power with a USB-C rechargeable pack | DMG-01 players who want to ditch AA batteries |
Where each product wins
For a cleaner PS1 picture: The PS1 kit takes the console's digital signal straight to a modern display, which avoids the analog conversion step of external converters. You get 480P and 1080P resolution options, a built-in OSD menu, three video modes, six aspect ratios, and adjustable deinterlacing.
For a Game Boy you can recharge: The RetroSix CleanJuice is a power supply unit made for the DMG-01. It's built in the United States, and because it's a battery pack rather than a video accessory, it solves the daily problem of keeping a classic handheld ready to play.
Product notes
For PS1 Digital to Digital HDMI Mod Kit For Playstaion PS1 Console

This kit includes a PCB and flex cable that must be soldered into the console, so it's not a plug-and-play project. The product calls for good welding skills and doesn't ship a paper manual; you can request the installation manual after the kit arrives. If you're comfortable with soldering, the payoff is a PS1 that outputs a clean digital image with several display adjustments. The main limitation is the installation: it needs a steady hand and some experience, and the included ribbon cable is designated for the PU-23 CXD8561CQ board variant. That makes it a job for a careful modder, not a quick weekend swap.
RetroSix CleanJuice USB-C Rechargeable Battery Pack Mod Kit for Game Boy DMG-01

This battery pack is made specifically for the Nintendo Game Boy DMG-01 handheld and the console, so it's a targeted power upgrade rather than a universal accessory. It comes from RetroSix and is made in the United States. The USB-C charging is the standout convenience: you can recharge the pack with a modern USB-C cable instead of hunting for AA batteries. If you play your DMG-01 often, this is a direct solution to the handheld's biggest annoyance. The limitation is scope: it's built for the DMG-01, so it won't power other handhelds, and it doesn't change the way games display.
Final choice by use case
Choose the PS1 Digital to Digital HDMI Mod Kit if your priority is a modern TV setup and you're ready to solder. It costs $48.50 and turns your PS1 into a console with modern digital video output. Choose the RetroSix CleanJuice USB-C Rechargeable Battery Pack Mod Kit if your Game Boy DMG-01 gets regular play and you want a rechargeable power source. It costs $35 and keeps your handheld charged. Both are legitimate gaming replacement parts mods, but the right one depends on which console is getting more of your time.
