Something just caught my eye :S
Well, maybe not for some people that this will work for with the Disc Read Error on V9s.
However, upon inserting a fairly scratched DVD-R movie on OPTODISC media, it said Disc Read Error. At this point I almost shit myself because I thought the board died. However, upon putting a Retail music CD in and / or a DVD-R PS2 Backup or PSX Backup, it worked fine. So if maybe retails still work for people getting the disc read error, then maybe its the media, maybe im wrong but its just a guess at the v9 problem.
Also, I used the VIAs and not the CDX Chip Legs for this V9
