You have to change the INTRA_SECTOR_GAP: http://cbmrom.trikaliotis.net/listings/2031-01.lst You can find it at $F5DB (F5DA: ldx #INTRA_SECTOR_GAP) and $FD1F (FD1E: ldx #INTRA_SECTOR_GAP). Other than that, you also have to adjust the ROM checksum (at $FF35 in the 2031 ROM), or disable the ROM selftest. Regards, Spiro. -- Spiro R.
