Contents • • • • • • Function and construction [ ] Modchips operate by replacing or overriding a system's protection hardware or software. They achieve this by either exploiting existing interfaces in an unintended or undocumented manner, or by actively manipulating the system's internal communication, sometimes to the point of re-routing it to substitute parts provided by the modchip. Most modchips consist of one or more (,, or ), often complemented with, usually packaged on a small to fit within the console system it is designed for. Although there are modchips that can be reprogrammed for different purposes, most modchips are designed to work within only one console system or even only one specific hardware version. Modchips typically require some degree of technical acumen to install since they must be connected to a console's circuitry, most commonly by wires to select traces or chip legs on a system's circuit board.

Hi in this vid I will be installing a £9 PSX MM3 MOD CHIP! This video shows how I got on installing on a. Playstation & PS One Mod Chip Installation. PS One Portable Modchip Installation Playstation Modchip. Recently, I have been making some guides on how to create your own PSX modchip using specific programmers and sometimes its original software and. *Important Note 1* If your installing the MM3 chip into the SCPH-100X series, it will NOT be stealth due to way that model has been made.

Some modchips allow for installation by directly soldering the modchip's contacts to the console's circuit ('quicksolder'), by the precise positioning of electrical contacts ('solderless'), or, in rare cases, by plugging them into a system's internal or external connector. Memory cards or cartridges that offer functions similar to modchips work on a completely different concept, namely by exploiting flaws in the system's handling of media. Such devices are not referred to as modchips, even if they are frequently traded under this umbrella term. The diversity of hardware modchips operate on and varying methods they use mean that while modchips are often used for the same goal, they may work in vastly different ways, even if they are intended for use on the same console. Some of the first modchips for the known as drive chips, modify the behaviour and communication of the optical drive to bypass security.

While on the, a common modchip took advantage of the fact short periods of instability in the CPU could be used to fairly reliably lead it to incorrectly compare security signatures. The precision required in this attack meant the modchip made use of a CPLD.

Other modchips, such as the XenoGC and clones for the, invoke a debug mode where security measures are reduced or absent, in this case a stock was used. A more recent innovation are optical disk drive emulators or ODDE, these replace the optical disk drive and allow data to come from another source bypassing the need to circumvent any security. These often make use of FPGAs to enable them to accurately emulate timing and performance characteristics of the optical drives.

History [ ] Most cartridge-based console systems did not have modchips produced for them. They usually implemented copy protection and regional lockout with game cartridges, both on hardware and software level. Converters or passthrough devices have been used to circumvent the restrictions, while flash memory devices () were widely adopted in later years to copy game media. Early in the transition from solid-state to optical media, CD-based console systems did not have regional market segmentation or copy protection measures due to the rarity and high cost of user-writable media at the time.

Modchips started to surface with the system, due to the increasing availability and affordability of CD writers and the increasing sophistication of DRM protocols.

In addition to circumventing regional lockout and copy protection mechanisms, modern modchips may introduce more sophisticated modifications to the system, such as allowing the use of user-created software (homebrew), expanding the hardware capabilities of its host system, or even installing an alternative operating system to completely re-purpose the host system ( e.g. For use as a ). Anti-modchip measures [ ] Most modchips open the system to copied media, therefore the availability of a modchip for a console system is undesirable for console manufacturers. They react by removing the intrusion points exploited by a modchip from subsequent hardware or software versions, changing the PCB layout the modchips are customized for, or by having the firmware or software detect an installed modchip and refuse operation as a consequence.
