easy...just write a small assembly prog. to disable all but NMI, switch
to full rom above $8000, and copy the roms to various other blocks...
something like below...but you then have to copy it out to disk or
wherever...do it block by block...same way as you use the 512k cocoIIIs
to do disk copying in single passes.

orcc #$50; lda #rom_setting; sta $ff9x ldx #$8000; clra
loop2
sta #$ffa2; ldy #$4000
loop1
ldb ,x++; stb ,y++; cmpy #$6000; bne loop1; inca; cmpa #$4;
bne loop2; andcc #$af
