Not only the new batch of Sony machines (HB-20 and maybe even the rest of the family, HB-10, HB-201,etc); but also the Toshiba machines seems that they dislike this mirroring. Sadly none of my machines are the offeding ones... ...or maybe

Do those machines have a different type of VDP? Is there a list of machines with such a VDP?

Is "VDP Pirates" also one of the programs that fails? (I remember someone said it wouldn't work on a Toshiba HX-10.)

It uses the standard SC0 mode, just some screen splits to change the pattern table and color register. As it's heavily synchronized (without sprites ) any external hardware plugged that uses interrupts could mess the splits; but the VDP type doesn't matter.

The machines that have been reported as "weird" (all of them seems to have the Toshiba VDP) are:

Toshiba HX-10
Toshiba HX-20
Sony HB-10P

But there're some few reports that talk about having such computers and testing sucessfully the mirroring....maybe some cheap T6950 revision?

It would be very interesting to see the Sudoku game running on these machines. The black and white intro is also screen 0 and using heavily synchronized code. Would be very interesting to hear if that part fails running on the machines you mention.
