are cdda tracks really needed for cdda games?

[hrb2k]

i have a us/ntsc dc.

i binhacked the 4 *.bin files, 1st_read,bin, 2_dp.bin, maigo and sg_dplder.bin.

but it seems as if the 1st_read.bin has 2 instances of "cd001". binhack only changes the first instance. do i manually have to change the 2nd instance in hex workshop?

thanks.
