Month-long modding project lets him go back to the 32-bit past on the go.
When the PlayStation Classic went on sale last month to celebrate the original Sony System’s 24th birthday, Japanese Twitter user @NIWAchannel grabbed one right away. But more so than being excited to play the bundled collection of classic 32-bit games, @NIWAchannel couldn’t wait to tear the mini retro system apart.

早く改造したいー#PlayStationClassic pic.twitter.com/PtdRjNZqJC
昨日の夜、中身をずーっと眺めてやっと改造プランが決まりました!

今日から少しずつやっていこう。
お楽しみに^ ^#PlayStationClassic pic.twitter.com/aGc29J5dcl
Just two days after he’d purchased his PlayStation Classic, the pieces were laid out on his table, and a plan was laid out in his head. Because for @NIWAchannel, a PlayStation Classic wasn’t enough. He wanted a PlayStation Classic Portable.
In a way, it’s really not such a greedy ambition, since the PlayStation Classic itself is as compact as many portable gaming systems. @NIWAchannel would still need to figure out a way to turn the processor into a complete game machine, and the first order of business was sorting out how to add controls.
まずは分解。

初代のコントローラと比較。
microUSBケーブルが普通に刺さってるー。断線してもメンテしやすくていい設計だね^ ^
フレキなのでここに手を入れるのは改造初心者の私には難易度高いなぁ。汗#PlayStationClassic pic.twitter.com/n5trJEbHmH
とりあえず配線確認して、初代プレステ(オリジナル)のコントローラ基板をのこぎりでカット。配置の確認までしたところ。早く完成させたいなぁ。#PlayStationClassic #改造 pic.twitter.com/kaFy4A3wvR

@NIWAchannel’s solution was to slice open an original PlayStation controller, wire its internals into the PlayStation Classic’s innards, and attach the left and right halves of the controller to the sides of the mini system.
少し作業しました。

今回はちょこっとだけコントローラの配線をした感じー。
ここが終われば完成までもう少しかなー。#PlaystationClassic #改造 pic.twitter.com/boOOzkgvPW
まだ改造途中だけど、シルエットはこんな感じ。

Of course, being able to control a game isn’t much good if you can’t see it, so the next task was to add a screen. For that purpose, @NIWAchannel opened a rectangular hole in the top of his rapidly evolving PlayStation Classic, one big enough to fit a 3.5-inch LCD display.
今現在の改造状況。

内蔵のモバイルバッテリー駆動で、増設コントローラーでのプレイが可能。液晶も内蔵。
が、なんか三角と四角ボタンがうまく動かない。どうも配線の接触が微妙な様子。。
やり直すかー。
見た目は後でよくする予定^ ^#PlayStationClassic #改造 pic.twitter.com/rFNi9lETtW
Now all the system needed to be truly portable was a power source, so @NIWAchannel plugged it into a 4,000-mAh battery, and his PlayStation Classic Portable was operational.

結局、コントローラの配線は全部やり直したー。
— にわ@チャンネル (@NIWAchannel) December 26, 2018
あとは液晶とバッテリーを中に入れてしまえば機能的にはほぼ完成かな^ ^#PlayStationClassic #改造 pic.twitter.com/GwA9cQ23w3
But @NIWAchannel wasn’t quite done tinkering. For starters, he wanted the screen to be flush and the battery internal. Also, with the screen occupying what would ordinarily be the “top” of the console, his modded system no longer had the original PlayStation’s iconic circular clamshell ridge, so he removed the required pieces from a full-scale PS1 and added them to the back of his self-made portable.

Other improvements include stereo speakers, a volume control knob, a headphone jack, and a micro USB charging connector.
まだ手を入れるところは沢山あるので仮組だけど、ひとまず普通に遊べるところまで出来ました^ ^

こんなダサいの作ってる人はなかなかいないんじゃないかなー^ ^#PlayStationClassic #改造 pic.twitter.com/TCTbQv6Hvb
中身はこんな感じ。

液晶と各種コード類で本体内がキツキツになるので、バッテリー分の容量確保にはこんな感じで対処しました^ ^#PlayStationClassic#PlayStationClassicPortable#PScP pic.twitter.com/lPi2cPEwxl
With only an hour every day after work to spare for the project, @NIWAchannel said it was slow going, but on January 1, he sent out the triumphant announcement that his PlayStation Classic Portable was complete!
完成しました。

https://twitter.com/NIWAchannel/status/1080661063241068545Of course, with Japan’s strict ways of dealing with modded console resellers, @NIWAchannel’s PlayStation Classic Portable is strictly a personal project, and not for sale. Still, it’s an awesome example that a portable PlayStation Classic can be done, and a great project idea for any other techno-savvy DIY fans.
