PSX Development With Unity And LUA

April 18, 2026 by 9 Comments

The Unity game development platform was first released in 2005, long after the PlayStation had ceased to be a relevant part of the console market. And yet, you could use Unity to develop for the platform, if you so desire, thanks to the efforts of [Bandwidth] and the team behind psxsplash. 

Yes, it really is possible to design games for the original PlayStation using Unity and Lua. Using a tool called SplashEdit, you can whip up scenes, handle scripting, loading screens, create UIs, and do all the other little bits required to lash a game together. You can then run your creation via the psxsplash engine, deploying to emulator or even real hardware with a single click. Currently, development requires a Windows or Linux machine and Unity 6000.0+, but other than that, it’s pretty straightforward to start making games with a modern toolset for one of the most popular consoles of all time. Just remember, you’ve only got 33 MHz and 2MB of RAM to play with.

We still love to see the legendary grey machine get used and hacked in new and inventive ways, so many decades after release.

How Resident Evil 2 For The N64 Kept Its FMV Cutscenes

February 3, 2026 by 13 Comments

Originally released for the Sony PlayStation in 1998, Resident Evil 2 came on two CDs and used 1.2 GB in total. Of this, full-motion video (FMV) cutscenes took up most of the space, as was rather common for PlayStation games. This posed a bit of a challenge when ported to the Nintendo 64 with its paltry 64 MB of cartridge-based storage. Somehow the developers managed to do the impossible and retain the FMVs, as detailed in a recent video by [LorD of Nerds]. Toggle the English subtitles if German isn’t among your installed natural language parsers.

Instead of dropping the FMVs and replacing them with static screens, a technological improvement was picked. Because of the N64’s rather beefy hardware, it was possible to apply video compression that massively reduced the storage requirements, but this required repurposing the hardware for tasks it was never designed for.

The people behind this feat were developers at Angel Studios, who had 12 months to make it work. Ultimately they achieved a compression ratio of 165:1, with software decoding handling the decompressing and the Reality Signal Processor (RSP) that’s normally part of the graphics pipeline used for both audio tasks and things like upscaling.

Subverting PS4 And PS5 Through The PS2 Emulator

October 3, 2022 by 7 Comments

Game console hacking remains a fascinating area, and we’re glad when someone brings the spoils of exploration for us to marvel at. This time, we’re looking at the [mast1c0re] hack story by [cturt] – an effort to find bugs in PS2 emulation toolkit present on Sony PlayStation 4 and 5 consoles, proving fruitful in the end. What’s more, this exploit seems unpatchable – not technically, but under the Sony’s security practices, this emulator falls under the category of things they refuse to patch when identified.

In this story, we’re taken on a journey through the PS2 emulator internals, going through known-exploitable PS2 games and learning about a prospective entry point. Circling around it, collecting primitives and gadgets, bypassing ASLR on the way there, the emulator is eventually escaped, with a trove of insights shared along the way. As a demonstration, [cturt] successfully loaded a different PS2 game from outside the PS2 emulator, transferring it to the PS4 over WiFi!

Burning Your Own PS1 Modchip Is Easy

November 1, 2020 by 18 Comments

The original Sony PlayStation came out just in time for CD piracy to really start taking off. Aware of this threat to sales, Sony engineers included a copy protection and region locking mechanism that placated executives and annoyed end-users alike. [MattKC] explores how this copy protection worked, and how you can burn your own modchip at home for just a few dollars.

Sony’s method of copy protection relied on steps taken during the manufacturing process, pressing a special groove into the game media that regular CD burners couldn’t replicate, a topic our own [Drew Littrell] has covered in depth. This groove contained a four letter code that could be read by the console, corresponding to the region in which the game was sold. The console would read this groove on startup, and check that the code in the game matched the code in the console before booting. Modchips circumvent this by injecting a spoof code into the console that matches the local region, regardless of what is read off the disc. This has the effect of both allowing users to run bootleg CD-Rs, homebrew code, as well as games from other regions.

Today, we’re blessed with the Internet and cheap hardware. As [MattKC] demonstrates, it’s no longer necessary to mail-order a chip from a dodgy ad in the back of a games magazine; instead, one can download source code and flash it to a commodity PIC microcontroller for just a few bucks. With the chip soldered in to the relevant points of the PS1’s motherboard, you’re good to go.

As far as console modding goes, the PS1 is a great platform to start with — simple to work on, and also the best selling console of all time, so the stakes are low if you mess up. Video after the break. Continue reading “Burning Your Own PS1 Modchip Is Easy” →

Tearing Apart The Nintendo PlayStation

July 16, 2016 by 30 Comments

The mid 90s were a weird time for video game hardware. There were devices that could play videos from compact disks. Those never caught on. Virtual reality was the next big thing. That never caught on. The Sony PlayStation was originally an add-on for the Super Nintendo. That never caught on, but a few prototype units were produced. One of these prototype ‘Nintendo Playstations’ was shipped to a company that went into bankruptcy. Eventually, the assets of this company were put up for auction, and this unbelievably rare game console was bought by [Terry Diebold] for $75.

[Terry] allowed [Ben Heck] tear into this piece of videogame history, and he has the video proof that this was a collaboration between Sony and Nintendo.
