Homebrew differences between backup loader gamma and usb loader gx

[dragon9000]

for me the gamma backup loader plays most of my games well except for super mario galaxy the movie lags and rune factory frontier the movies lag a little. super smash bros brawl frezes on movies and subspace. same goes for usb loader gx. but mario galaxy and rune factory movies play with no lag on usb loader gx. but i have a problem getting sonic unleashed to load it freezes after the movie on usb loader gx. but it will play full speed using gamma backup loader. i just want to know why that is?

Backup Loader Gamme was used for disc backups. Usbloader GX is used for USB backups, that's the difference.
Better use NeoGamma than Gamma it's way better.
