please, use english only. I don't need Brazilian, and it will not help anybody to find your message in brazilian here if it's a question and not an answer.
the best format is FAT32, it's compatible with EVERYTHING. all consoles and all homebrew and all devices over the world supports FAT32. PS2, PS3, Wii, WiiU, etc.
Wii games bigger than 4GB can be played on FAT32 too.
NTFS is for PC (not for console). for example saving big files (videos, full ISO, backups, etc.)
I don't understand PT-Br, but I noticed he said "emulator".
Yes, you can play gamecube games on emulators (Dolphin) on your PC with a NTFS drive.
If nintendont added NTFS support, then he can use it too.
But there is no USBLoaderGX 1263. You need to launch nintendont directly from The homebrew Channel.
if it works from HBC, it's a problem of USBLoaderGX. It needs an update.
if it does not work on HBC, it's not USBLoaderGX problem, it's nintendont not compatible with NTFS.
