How can I make bootable CDI from GDI file?

[bshi02]

Is there any detailed tutorial which teach how to make dreamcast bootable cdi from gdi file?
and Is there any tools which make any size of dummy file as I want?

i don't have the time right now to write up a tutorial for ya.
but a quick take is.
this is for making audio/data 117002 cdi
download gdrom explorer.
use japanese cakes gd rom explorer
extract .gdi
extract filelist.txt for sort order (might be getting isobuster mixed up with the correct name of filelist? maybe gdromexplorer extract correct sort)
make a sort.txt from filelist.txt (use sort.txt creator)
use a hex editor on main bins and edit lba
search cd00 8 spots from left edit (5c 2e for 11702 lba, 6e b0 for 45000 lba)
5c 2e for this example
use binhack on ip.bin and 1st_read
binhack ,enter name of binary - 1st_read.bin , enter name of bootsector - ip.bin, enter LBA desired 11702 in this example.
download cdi4dc and cdrtools
put the cdrtools files in a folder with cdi4dc and create bat file.
put game data in folder named data.
put sort txt file in root folder that has cdrtools and cdi4dc.
use this batch script with cdrtools:

mkisofs -C 0,11702 -V "input desired volume name" -G ip.bin -l -sort sorttxt.txt -o data.iso data
cdi4dc data.iso "input desired cdi name".cdi
del data.iso

Done!

I'd suggest hack4 over bin hack but they're mostly interchangeable.

Great succinct guide.

Thank you very much for uploading whole of tutorial which include making dummy file!
Frankly speaking,I intend to replace 1ST_READ.BIN and IP.BIN with hacked one in gdi file,Because there is some game which is impossible to run in hdd moded dreamcast with retrodream, and I also intend to push the actual data to the outer ends of the disc by padding dummy files in saturn cdimage file.
