Hacking correct 1:1 iso size

[lilpuddy31]

I am just curious, what are the correct sizes for 1:1 Gamecube and Wii isos?

All my Gamecube isos are 1.35 GB (1,459,978,240 bytes)

My 2 Wii isos are Kirby's Return To DreamLand: 4.37 GB (4,699,979,776 bytes)
and Metroid Prime Trilogy: 7.91 GB (8,497,659,904 bytes)

I've tried looking around on Google, but couldn't find a straight answer for a 1:1 iso...

Those are all standard sizes for 1:1 ISOs (and FYI, the standardized units for storage is 1000 bytes for 1 kilobyte and so on, so it'd be 4.7GB and 8.5GB respectively). The reason why MPT is nearly twice the size instead of the usual 4.7GB is simply because it's one of the few dual-layer games on the system (other examples are SSB Brawl and Xenoblade Chronicles).

Well I found this in another thread, posted by Cyan

Wii single layered
4 699 979 776 bytes

Wii double layered
8 511 160 320 bytes


GameCube
1 459 978 240 bytes

It seems that my iso for Metroid Prime Trilogy doesn't match that...

I'm confused...
