Shrunk ISOs on Nintendont

[ApeApe]

Second time posting here, so apologies if I have made a mistake or broke a rule. A little background, 3 usbs Lexar 32GB. One of which held quite a few GameCube games. After not playing on my Wii for sometime, the ISO roms shrunk. They are detailed as such in the nintendont menu and when checking them on my computer, they are definitely smaller than they were originally. I tried seeing if I could convert them to NKit and then convert them to ISO, but that doesn't work. Please let me know if there is a fix or if I have to redownload & convert them.

ISOs don't shrunk by themselves. It's not like they decide to reduce their filesize out of nowhere.

If you've got CISOs, you can convert them using NKit back to ISO and then do as you please.

They are definitely not CISO. I put them in, as ISOs, black text. Months of not using it, appears as red text. On my computer, they are still seen as ISO, but they are smaller. Could it be that they were corrupted in some way?

If anyone is observing, I have been messing around with it. I used Alien Hominid to be the testing rat. I put it through DMTool, it was at 55 thousand. After, it was at 440 thousand, (I should've wrote the exact sizes, didn't). From there, I put it through NKit, and that failed. However, when I turned off full verify, I had it back to 1.35GB. Now the text color is back to 1:1, but I get a black screen.

NKit is very picky with ISOs, they must be non tampered as much as possible (disabling full verify doesn't fix anything).

If you could hash-verify your ISOs before using NKit that would solve many issues. NKit was supposed to restore ISOs original content making them "hash-verifiable", but it seem to work only with ISOs that have been already processed by it and not just any ISO out there.

Late response, but DMToolBox has to be set like this in order to succesfully shrink Gamecube ISOs:

Not all Gamecube isos will work with Nintendont when shrunk! Be sure to read the Compatibility List before you attempt to shrink any Gamecube ISOs!

I'm pretty sure an ISO can't shrink by itself and then get back to normal... by itself.
So... if that's truly the case, be sure your device (SD or USB or HDD) isn't getting corrupted or something.
Also, as always: utilize MBR boot sector formats with 32k cluster size to prevent any issues.

I decided to just delete and redownload the games that were affected. It's not the first time this usb has given me issues. Perhaps it's a bit defective. Might change later on.
