is there a way to shrink a dreamcast image?

[johnnybravo1]

hello guys,
i have extracted several of my dreamcast games from their original cds, but now they occupy too large a space. is there a way to shrink them, like we is done with the gamecube images?
thx.

of course. there are several tools for shrinking dreamcast isos.
you have to downsampling movies and sound files.
take a look of this site : http://homepage.ntlworld.com/menace-59/gd-rom_stuff/
btw. how do you copied the original DC Games?
Coders Cable, BBA or the "swap trick method" ?

As a matter a fact, i am not good in computer tech. i hired a technician to do it.

if you want to emulate, then you dont must shrinking. you can make a iso with all files and use bin2boot to make a selfbootimage, then you can mount with dtools (or whatever).

You hired a technician to rip your DC games... wow..

lets not get testy now, it's just a little uncommon when someone rips games like this

 

[johnnybravo1]

ok, sorry for that.

Actually I'd pin my guess, that you didn't get a technician to rip them, I'd bet on you downloading them ...but hey assuming that is actually true (yeah and the pope is buddist, and I am Lord Llama the 22nd). Try 7zip, it compresses ISOs and ROMs extremely well ( www.7-zip.org ) and use the beta version

thanks.
problem is - they are not playable anymore unless you uncompress them.

Burn them to CD/DVD or compress them with NTFS.

Remove the dummy files, if there is any.

 

[johnnybravo1]

good. i´ll tell my technician to find those dummy files. regarding ntfs compressing, it has no overall gain, because the OS still informs the former size.
so i´ll compress them with winrar and uncompress the ones not compatible with the current emulator version. too bad most of my games are not compatbile, but chankast has performed a giant step. congrats, chankast team.

Look in the properties and an uncompressed iso will normally be smaller using NTFS compression. In the following case I gained 239MB with no file modification and works in Chankast fine without uncompressing.

 

[johnnybravo1]

good. so it is still possible to mount the iso on the daemon tool. i´ll give it a try, thx.
