Game Console Modifications and Hacking

After 12 years , the "unhackable" Xbox One has finally been hacked thanks to the new Bliss exploit that triggers a hardware glitch in the Xbox One console Boot-ROM. In today's episode we take a closer look at the exploit and discuss what this could mean for all things unsigned code, homebrew and the preservation of Xbox One games.

Sony was an unstoppable force in the early 2000s. The release of the PS2 went swimmingly, and gamers worldwide were enjoying the technological advancements made by the console. Despite going on to become one of the best-selling consoles of all time, Sony wasn't fully satisfied with how things were going later in the PS2's lifespan. Much like its predecessor, the PS2 had a serious security problem. Once the copy protection was broken, it became the wild west, so much so, that if you buy a used PS1 or PS2 in 2026, there's a good chance it has some kind of modchip inside. Things had to change for the PS3, and Sony had a plan.

For a late-1990s engineer with good soldering skills, many a free pint of beer could be earned by installing modchips on the game consoles of the day. Modchips were usually a small microcontroller connected with a few wires to selected pins on the chips or pads on the board that masked or overrode the copy protection and region locking. This scene was brought back for us by a recent [Modern vintage gamer] video looking at the history of console hardware mods, and it’s worth a watch (see the video, below).

The story starts in 1996 with the original PlayStation, largely the source of those free pints for a nascent Hackaday scribe back in the day. Along the way, as he expands the story, we find other memories, for example, the LPC bus-based hijacks of the first XBox console, and the huge modding scenes on both that machine and Sony’s PS2. The conclusion is that this community left its mark on today’s consoles even though the easy hardware hacks may be a thing of the past on the latest hardware, and as past Hackaday articles can attest, jailbreaking older consoles still has a way to go.

The Sony PlayStation 2 contains a chip called MechaCon. Its job was to be the system's ultimate security gatekeeper, controlling disc authentication, region locking, MagicGate encryption, and KELF file decryption. For years, it was considered the last unbreakable barrier in PS2 security. Modchips could only bypass it. But buried inside Sony's redesigned Dragon MechaCon it was discovered that it was EEPROM patchable and exists a factory service feature.

In this video take a closer look at the exploit chain from the PS2's boot certification handshake through the cryptographic failures, and the tools that finally cracked it open: MechaDump and MechaPwn. The factory backdoor Sony built for their own service centers became the front door for the homebrew community.

I have a PS3 for quite a while now, and for years it worries me, the worst part to find replacements is the original controller. With very important functions being bound to the PS button, and my console being compatible to my knowledge only with HEN, the lack thereof would easily be a problem, and in my case, I'm already having to use the PS Move controller I have for PS button functions.

When I watched the video, I remember the thought crossing my mind: would this method help circumventing this issue?

Thanks in advance!

With the launch of optical media in game consoles such as the Sony PlayStation 1. The console could be hacked with a use of a simple modchip - an unauthorized hardware modification that was soldered directly onto the motherboard. This was done to circumvent security features. While the original goal was for piracy and backups, as modchips evolved, so did their use cases. Everything from Region Free, homebrew, emulators, makeshift development kits and more were soon possible. In today's video we look at the earliest modchips and how they shaped the video game landscape.

Since the PlayStation 5's release in late 2020, console hackers have attempted to gain complete access to the system by discovering and exploiting vulnerabilities, using software exploits to access features not normally available to consumers.

But on New Year's Eve, console hacking groups detonated another sort of explosive that could have massive consequences for the PlayStation 5 hacking scene, opening the door for permanent jailbreak, custom firmware, emulation, and much more.

Got a second hand Wii earlier this year, but got some weird but sporadic glitches, like certain Wii ROM formats not working, and that the previous owner, whom I still talk to, didn't recognize said glitches.

As I could circumvent the glitches I found, I didn't mind them enough to care. But then, as I started tinkering with the GameCube compatibility, I started seeing way more errors.

CleanRip, when starting, would estimate dumps to take, as a manner of speaking, 1/256 of an eternity. Physical games couldn't save through Nintendont. ROMs wouldn't appear on USB Loader GX. And maybe a few more errors I'm forgetting.

It was fun. /s

Also can't remember why I didn't try another USB, but maybe it was a mix of not having devices easily available and coning from consoles where for things to work, the stars would need to align just right coughcoughps3coughcough

Then I had to put it aside for some months because life happens.

Then, some months later, 3 days ago, I noticed the USB stick I had gotten somewhat recently wasn't being used and the data in it was minimal, and I remembered the warnings about trying different USB sticks if problems appeared.

Been using everyday since, the stuff I put in the USB has been working near flawlessly! Even the USB recognition issues from the Wii, which I had read that is spotty indeed, hasn't yet happened.

So moral of the story, if you see weird behaviour when modding the Wii, please do try another stick, even if you have to buy a smaller one from your local electronics shop.
