If you want to play a PS ONE on a modern display, you need a way to convert its signal to HDMI. External converters exist, but many add lag or soften the picture. The Hispeedido PS ONE Digital to Digital HDMI Mod Kit takes a different approach: it installs inside the console to send a native digital signal to your TV.
Quick verdict
At USD 51.50, this kit is for someone who is comfortable with a soldering iron and wants a cleaner HDMI path than an external converter. It supports 480P and 1080P output, includes an on-screen menu, and offers three video modes and six aspect ratios. The catch is the install: it requires soldering the included PCB and flex cable into the console, and the manual is only available digitally after you request it.

The board and flex cable are designed to work with the PS ONE's digital video signal. Once installed, you get 480P or 1080P HDMI output, with an OSD menu to switch between Mild, Standard, and Dynamic video modes. There are six aspect ratio options: the first three run at 480P and the last three at 1080P, so you can adjust the shape and resolution to fit your setup. Deinterlacing is also adjustable between Bob and Weave. Because the signal stays digital from console to HDMI, the kit avoids the analog conversion step that external adapters rely on. The listed price is USD 51.50, and it comes with a 1-year manufacturer warranty.
Who it suits
This mod kit is aimed at retro-gaming enthusiasts who are already doing console repairs or mods. If you own the right PS ONE board and know how to solder, you can turn the console into a clean HDMI source without adding a bulky adapter. The OSD and multiple aspect ratios are useful for matching the picture to different TVs, especially if you switch between 4:3 and widescreen displays.
What stands out
The digital-to-digital path is the main advantage here. Because it keeps the video signal in the digital domain all the way to the HDMI output, it sidesteps the analog conversion that external converters typically perform. The built-in OSD gives you control without leaving the game, and the adjustable deinterlacing (Bob or Weave) is a thoughtful extra for a console from this era, since it lets you choose between smoother motion and a more static presentation.
Meaningful trade-offs
The biggest limitation is the installation. This is not a plug-and-play device. You have to solder the PCB and flex cable inside the console, and the instructions are not printed on paper. The kit requires good soldering skills, and you need to request the installation manual after receiving the product. That means you should be confident working with small components before buying. Also, this kit uses the PSONE CXD8561CQ two-ribbon cable configuration, so your console must match that board layout.
Bottom line
If you are comfortable with soldering and want a native HDMI signal from your PS ONE, the Hispeedido mod kit is a practical upgrade. At USD 51.50, it provides 480P/1080P output, an OSD, adjustable video modes, aspect ratios, and deinterlacing, all in a small board that fits inside the system. The manual and soldering requirements are the trade-offs, so only buy it if you are ready to open up the console and work on the board.
