add null filler infront each bank 0x8192 bytes at
0, 10000, 20000, 30000
add 65,536 at 0x000000
cut 0x30000 to 3ffff
paste at 0x0
banks are now ordered 0-1-8-9
clear all null filler by setting it to 0xff

when you say add 65,536, you mean add 65536 bytes at 0x000000?

if i follow the step without put the 65536 bytes at 0x000000 the file is 256ko. but i see something wrong in the file the vid block when i cut 0x30000 to 3ffff and paste at 0x0, the vid block normally will be at 3FF06 move to 0FF06. maybe something wrong with that
