The ROM ordering is different: - row order is linear, 0-63 - bit order from the left, 7-0 - page order, per bit column, i think it's: 7 6 5 4 3 2 1 0, 15 14 13 12 11 10 9 8 http://tsk-tsk.net/net/temp/xl25_good.bin
BTW, Olivier Galibert did a large update on MAME's disassembler. It supports paged layout and LFSR flow now, TMS1000 live disassembly is much easier to follow.
