Pozatym problemów może być masa w innych miejscach. Taka zgadywanka jest trochę bezpłodna. Może poprostu zamieść cały kod...
To jest właśnie cały kod :) Uszczupliłem go do minimum, tak aby było wyświetlenie obrazka i podmiana vbl'a
Tzn, brakuje jeszcze init'a. Ale jak pisałem wcześniej. Jest z tutoriala perihelion'a + moje ze cztery linijki.
Wygląda tak:
init
* set supervisor
clr.l -(a7) clear stack
move.w #32,-(a7) prepare for user mode
trap #1 call gemdos
addq.l #6,a7 clean up stack
move.l d0,old_stack backup old stack pointer
* end set supervisor
* save the old palette; old_palette
move.l #old_palette,a0 put backup address in a0
movem.l $ffff8240,d0-d7 all palettes in d0-d7
movem.l d0-d7,(a0) move data into old_palette
* end palette save
* saves the old screen adress
move.w #2,-(a7) get physbase
trap #14
addq.l #2,a7
move.l d0,old_screen save old screen address
* end screen save
* save the old resolution into old_resolution
* and change resolution to low (0)
move.w #4,-(a7) get resolution
trap #14
addq.l #2,a7
move.w d0,old_resolution save resolution
move.w #0,-(a7) low resolution
move.l #-1,-(a7) keep physbase
move.l #-1,-(a7) keep logbase

Ablolutnie żadna. Ale jak się tego nie robiło, a tylko o tym czytało i to z 15 lat temu, to trzeba znaleźć gdzieś te wszystkie adresy. Ale skoro już podałeś to dzięki :)
