I just installed MARS IV MA-705 modchip for V12 in 3 type of PSTwo's
70006 HK, 70004 EUROPE 70001 US
All machines wokring well with any kind of DISKS CD-R CD stamps DVD-R DVD Russian Stamps.
The chip is comming with Diode fix which is in the same package. The diode fix is especially desinged for this chip by MARS chip developers.
Only one thins which was strange for me thats the Playstaion2 logo problem.
Then you starting your console and then its booting your game and the time when Playstaion2 shoudl appear it's just scratching the logo no clear Plasystion2 logo just scratches.
All other part is working ok all games booting DVD movies ok PSoine Ok.
If somebody can explain why thats' nois sctratced logo is appearing instead of normal Playstaion2 logo?
