Modbo 4 0 Installation Instructions
Modbo 5 is not the best, modbo 4 v1.93 is. They're not compatible until v4 (with bios gap, no-bios gap not supported). The only one I know of that is supported by matrix infinity clones, not modbo (because I wrote the diagram myself) is the v2 gh-004 motherboard. A major difference we found between Modbo 4 and Modbo 745 is the Modbo 4.0 does work from v5 to v16 as advertised, but the Modbo 745 has trouble working in consoles under v9. Another bonus with the Modbo 4.0 is its now running the Matrix Infinity firmware v1.91 and is also possible to upgrade the firmware at a later date without any problems.
After struggling to install my Modbo 760 correctly for three days i finally cracked this thing.

Lacking a proper diagram for the Modbo 760 and GH-072-42 combination i used this one which is for a Matrix clone:

This diagram however has one point that doesnt match the Modbo 760, namely the Cx point. Thinking that there is only one point left unsoldered on the chip i assumed point Z on the chip should be Point Cx on the diagram.
At first my original FFX would load properly. Then all hell broke loose after about 5 resets of the console. I started getting messages like “DVD player is not set up”, legitimate PS2 games being identified as “DVD video”, the Playstation 2 logo would display as if the game was about to start, but then i got thrown back to the browser without any explanation. I thought i had fried my BIOS or laser and that the PS2 is dead.

Google suggested i should check for bridging and cold joints of B,G,H,I,U,O and P. This didn’t help and the problem drove me nuts.
As it turns out, just desoldering Cx and Z fixed the issue immediately.

I wasn’t able to find this information anywhere online, so I’m putting it here in case anyone faces the same issue.
