Isoloader issues (HDD mod + Bios mod)

[nicolas1400]

Hi SWAT, thanks for your quick reply.

One of the boards with isoloader problems is a VA0.
Bios mod worked OK (I used 3.3v sources accordingly)
But Isoloader refuses to play games. I am able to choose the game, adjust settings, but black screen occurs at the moment I actually run the game.
Is the hdd mod supposed to work on VA0 and VA1 boards? Or just VA1? I think there's no difference in the gd-rom pinout.

Here I attach a few pics of the problematic board:
