[DottMark]

Hi, i want to compress my gamecube games, afaik Nintendont only read iso and ciso, which is the best tool to do this?

use only dmtool box and make sure you choose 32k alligment or else audiostreaming games will be broken.

Yeah, use the DMTool box. Make sure to check the Nintendont compatibility list for games that work or don't work when compressed.

they shoudl all work compressed with dmtoolbox at 32k alligment, only games that dmtoolbox cant compress will fail but you will notice since the games like kirby air ride files get bigger than base iso lol

Didn't not know that.. Thank you for the info.

whaou! thanks for this post, I did'nt know it was possible to use compressed image with nintendon't!

You can use GC ISO Tool to do the job. It's a more complete solution and have more options.

nope gc iso tool breaks the alligment of many audiostreaming games, making them crash with nintendont. it shouldnt be uised, while most games dont have audiostreaming the ones that do are easily breakable with that app.

they arent compressed, they are trimmed, so you just loose the extra filezie that doesnt have anything on it and are made of padding.

Nkit (nkit iso format) does align the audio and tgc files to 32k. Why is dmtoolbox recommended instead?

Nkit iso is not recomneded for nintendont, many nkit isos dont even work, i cant count on how many reports we had of people using isos that crash only to find out they were nkit isos, they switch to full isos and everything worked, so i would never recommend nkit for nintendont ever.

even thge dolphin devs said it shouldnt be used for gaming read its reply

see dolphin dev reply.

And nintendont is much more picky than dolphin which can make many games crash and such.

I get the point, but can't see why dmtoolbox is different.
btw, many users can't distinguish between gcm, nkit.iso, iso... so i wouldn't trust that nonworking reports

I wanted to add ZSO support to Nintendont but I could never find the time. I'll give it a shot as soon as I can.

Swiss' developers at least recommend using Nkit to trim .isos (to the point that Swiss complains unless you use nkit or untrimmed)

The real efficacy test would be comparing nkit trim to dmtoolbox trim, not to untrimmed. For what it's worth, I haven't had a single problem with Nkit yet, and it's the only fully optimised trimming method. (Obviously there's only one optimum way!)

its very easy to see the difference. when you trim with dmtoolbox you dont swap file locations around, you just trim the padding they put at the end of the iso so if the game was 900mb and then they added padding to the end of the iso to reach 1.35gb, if you use dmtoolbox you get trim until 900 and done.

nkit moves file locations around besides trimming to do better shrinking and it probably will shrink agmes more which can be an issue depending on the game or way you play it because nintendont might expect that file to be at that location and it isnt.

Thx for the explanation. I tought that these inner movings applied to wii isos only, not gc.
To end this conversation, do you known positively about just one title that doesn't work as nkit? so i can see it with my eyes.

i dont know any single title, i heard people complain about games not working over the time and many of them were nkit isos complains, i dont recall any specific game name tbh, like i said, if it works for your games then nice, but please dont go to nintendont thread or github issues complain when a game crashes using a nkit iso before trying a vanilla iso.

Bumping for 2 reasons:

1- A long time ago I tried this DM ToolBox and my isos crashed no matter what. So, what would be the exact options to correctly shrink an iso? And can I checksum with DM ToolBox?

Extracted + 32K?
Optimized + 32K?

2- Will try tomorrow and don't want to lose this thread.

optimized and 32k and then install

of course the iso you feed it should be md5 checked with redump, putting a random broken iso or nkit.iso will not bring good results.
