Nov 27, 2011 So I was dumping my gamecube and wii games off of my wii and getting them ready for my new computer build to emulate them, and as I was reading a few posts on the cleanrip website (program used to dump games) I noticed that my gamecube games were 1.4 GB as opposed to 1.35 GB. Same with my wii games too 4.4 GB as opposed to 4.37 GB. The Nintendo GameCube (commonly abbreviated as GameCube, model number: DOL) is a home video game console released by Nintendo in Japan and North America in 2001 and Europe and Australia in 2002. The sixth-generation console is the successor to the Nintendo 64.
Why do we change the cluster size when formatting USB drives for storing GameCube games?
For loading GC Games with USBLoaderGX via DiosMios/Nintendont, format your usb drive's primary partition as FAT32 with 32KB clusters (also known as blocks). This increases performance by reducing the NUMBER of transactions required to perform a read/write operation at the expense of the (very negligible) LENGTH of time to complete a transaction; since it's reading more data per transaction.
I'm not certain, since I can't find a GameCube disk specification, but I don't think the 32KB cluster size is an attempt to imitate the on-disk storage format of retail GameCube discs; which may or may not be 32KB. Retail Wii discs however, actually DO use 32KB clusters. As far as I can tell, 32KB is simply the highest density of bytes per cluster that is supported by FAT32 and of course, by extension, Wii homebrew storage libraries.
If you're concerned about storage efficiency and you're using extracted images, you can find the optimal cluster size by calculating the mode of file sizes and using that number rounded up to the nearest multiple.
How to format a USB drive for storing GameCube games
Explanation:

Sectors contain bytes.
-S 512 means that we're specifying 512 bytes per sector.
Clusters contain sectors.
-s 64 means that we're specifying 64 sectors per cluster.
If we represent this mathmatically:
Or we can represent this visually:
This
-F value represents how many bits are used in file allocation table entries. The entries themselves are used to address individual clusters on disk. As the number of bits increases for each individual FAT entry, the higher the value it's able to represent and the higher the quantity of file allocation table entries that it can address.

To restate this, the more bits you use for file allocation table entries, the larger the numbers they can store. The larger the numbers they can store, the more FAT entries you can have. The more FAT entries you can have, the more clusters they can point to. The more clusters you point to, the more bytes they can contain. The more bytes they can contain, the more data your disks can store using this system.

We specify 32bits for the allocation table entries so that they can store a maximum of 4,294,967,296 entries (aka FAT32). This gives us a approximate maximum disk size of 8TB... but 4 high order bits are reserved ... only 28 are used...
To further illustrate, a 32-bit value has 32 binary places(2^32). When all of the bits are set to 1, as in the binary representation of the number 4,294,967,296:

(spaces added for clarity)
On 32bit CPU architectures, this is the value of a unsigned integer.
The datatype used in the FAT implementation is a signed integer which can store a maximum of 2,147,483,647 positive values represented in two's compliment form.

Recently, the number of game cases on my shelf has gotten to the point that it's becoming inconvenient to go through them to find games, so I've recently been moving away from using the original cases, going for the cases that can hold a ton of games.
For most consoles, this isn't a problem, as they fit the standard cd cases you find everywhere, which can usually hold up to about 120 discs.
However, the smaller size of GameCube discs make them more of a pain. While they (obviously) fit in the sleeves designed for full size discs, they don't stay in place very well and are likely to fall out, so I was trying to find something for them.
I found some marketed specifically toward GameCube games, but I also found some that are for MiniCD and MiniDVD. Are they the same size (or near enough to the same size that their sleeves would fit)?
If anyone has any experience in this, I'd appreciate it.
(Also, the relationship of this question to gaming is, admittedly, tenuous at best, so if somewhere more appropriate for this question, let me know.)

Gamecube CDs have the same diameter as MiniCD/DVD (which is 80mm).
A sleeve for MiniCD/DVD should also fit a Gamecube CD.
