- PSX game Spyro 2 had antipiracy protection which randomly removed items from game and told that functionality is not guaranteed on hacked version.
- PSX game Crash Bandicoot (naughtydog) had playable Spyro (Insomniac) demo game included and hidden in idle-screen. Spyro had the same with Crash Bandicoot idle-screen.
- making of Crash Bandicoot has a nice readup and there is an extended video documentary (2h14m)
- PSX discs have a wobble in the inner, unwriteable disc tracks, which modchips worked around. There is AtTiny85 OSS modchip 'PsNee'. There used to be black coloured burner CD-Rs (for aesthetics).
- There is an ODE SD-card reader to replace faulty CD lasers/drives if laser tuning does not work
- nsOne is a PS1 PCB recreation working project from 2025
- PlayStation Portable had pandora battery recovery mode long undiscovered. It was recovered because modified battery and MagicGate MemoryStick were still inside when someone had received it from manufacturer repair. <insert good link>
It came up with the "Nintendo PlayStation" project, a CD-Drive for upcoming SNES-console and became it's own console by Sony.
- You can modify a USB-C socket inside hollowed PS-Vita connector (done myself with microUSB sockets on defective ports)
- Buy µSD-Card PCB adapter for Vita game card slot.
- Buy µSD-card adapter for MemoryStick (also dual µSD); works well with SE phones and Sony PSP (except for PSP recovery with pandora battery due to no real MagicGate MemoryStick); adapter has ASIC inside; needs reformatting in dual µSD-card mode
- M2 MemoryStick micro is basically a shrunk down MemoryStick, they are electrically the same.
- Glitch PS4 Renesas MCU to revert to previous firmware <insert links>
- PS4 is vulnerable to BD-JB exploit which was 12-2024 updated - jar-loader integrated :)
- early PS3 prototype model had no GPU. As Cell Processor is complicated to programm, devs protested, Sony added NVidia GeForce 7 GPU onboard. It is impressive what Graphics can be squeezed out of Cell PS3, see Naughty dogs Uncharted 3 and its progression documentary
- All PS3 with CFW are able to run backwards-compatible PSX and PS2 games with official emulator. Phat PS3 has PS2 coprocessor.
- the CFW story behind PS3 Cell (+PSP) hacking is entertaining *keyword golden firmware, golden times*; fully hacked
- the documentary of Naughtydog Crash Bandicoot on PSX is insightful
- The Logo of PS1 is a standing 'P' with a lying 'S'.
- PS2 FreeMCboot MemoryCard update mechanism exploit, boot from USB | now FreePSXBoot for PS1 too | PS2 FreeDVDBoot to setup FreeMCboot (2020 way for no modchip at all)
- There was a FreeMCBoot exploit which tricks the drive into thinking it is a VIDEO_DVD in no need of game-piracy-protection (need to patch games first)
- PSP/PS2/PS1 have tons of emulators for other systems - There are many emulators for Sony Playstation with upsampling and AntiAliasing (look@ Retroarch/Libretro)
- PS1 lack of FPU has become its own renderer style. Also good read is copetti.org
- The round Sony Ericsson logo is a fluid joint of Sony 'S' and Ericsson 'E' (SE)
- Sony Ericsson phone scene is still (kept) alive :)
