I managed to get perspective on the Mode 7: http://pixelretro.hebergratuit.net/NesBox/m7.html
(Though I wonder how the calculation soft , for the moment I precalculation in C language).
But I would use a second background.
When I active ext BG ,I have the impression that the BG2 is identical to BG1.
He uses every 2 BG1H0FS/BG1V0FS.
On Secret of Mana, it uses
BG1SC $ 51
BG2SC $ 59
BG12NBA $ 44
and $4000, data on 4bpp
Of course I did the same , but with no result on screen.
I forgot something ?
