Further Note regarding compatibility:

We do not recommend this chip for asian v8 boards ( 39005, 39006, 39007). This is because there seems to be a compatibility problem with certain asian v8.

The chip have so far been tested and works fine on the 79000 and 79002. Hence, we expect it to work with other 7900x models as well.

FAQs

Can I play DivX and MP3 files using my PS2?
Yes, you can. It has been tested to be compatible with PS2 Mediaplayer 1.50. More information concerning the Mediaplayer can be found at the Links Section.

Why did you not include the Mediaplayer function as part of the modchip?
We did not believe that is as a good idea. PS2Reality specifically requested that they do not want to see their freeware used to sell other people products. (Mediaplayer is a freeware program.)

Can it play movies from other regions?
Yes, as long as your playstation 2 can support dvd output signal. it can not. For example on the whole, NTSC PS2 can only play NTSC DVD even though you have unlocked the region-lock problem. Whilst Pal PS2 can usually playback both NTSC and Pal movies. However, it is always better to use a standalone multi region DVD player for DVD movies.

Is it compatible with HDLoader & HDAdvance?
It works fine with both HDLoader and HD advance when using a standard IDE hard disk.

Does it support program that is on the memory card?
Yes it supports applications from the memory card. ie Dev 1

Does it support program that is on the HDD?
Yes it supports applications from the HDD. ie Dev 2

Additional information


V9 and v10 LA chip syndrome.
It is a well documented fact that the latest v9 and v10 machines suffer from a major problem. The LA chip has a tendency to die. After it dies, the only solution to get your machine working again is to replace the chip with an original LA6508 or a device called LA6508 RII. However, in both cases, it is quite a hard soldering job. (much harder than to install a chip). The following can be done to reduce the chances of the LA 6508 chip dying. Again do not attempt the simple modification unless you know what you are doing.

Firstly - the prevention - by far easier than the cure:
1) Carefully lift Pin17 of the LA6508 Chip,
2) Ensure no solder links it to the pad it was just lifted from,
3) Link Pin17 to 5 volts as demonstrated in the picture below.
