question for people who have R4

[Byuakuya]

Yeah I recently bought a 400 gig external HDD and after formatting it says 375 gig. I knew it was going to happen but still if you think about it, 25 gig is quite a bit to loose though.

Probably 16-18 DS games.
The Gameboy Advance games are smaller. So maybe 20 of those.

R4 can't play GBA games

as stated before, you didn't loose anything it is just how the ratio is setup.
