about VDP2 capabilities

[vbt]

i'm trying to use this mode on layer 1 :
16x16 tiles (2x2 char)
1 word
2x1 pages
in the documentation, it says (p.79) 2x1 pages means 128x64 tiles, when i test, with 2 pages modes :
mode 1x1 : i can only fill 32x32 tiles and next 32x32 is a copy of first page because i setup page 2 = page 1
mode 2x1 : i can fill 32x32 tiles, next 32x32 cannot be filled

does it means the documentation is wrong ? or 2x2 char mode reduces the page size ?

after some testing, i was not able to use 2 planes of 64x64 as mentionned in the documentation but 4 planes of 64x32, here is the working layout :

I will try to do a 2x2 plates (128x128)

 

[vbt]

1) plane setup doesn't allow 1x2 (64x128)

2) 2H x 2V with 1 word and 2H x 2V cells is available

after many testing the conclusion is 2x2 planes with 2x2 cells doesn't work. I didn't try on saturn but yabause & ssf emulate it the same way as 2x1.

scrolling possibilities are :
x : -2048 to 2047
y : -1024 to 1023 (and not to 2047)
