those are generally the best sites for file hosting, no ads/high storage space/high download speed, its more a problem of would there be legal problems by putting a download up containing all of the english lines. Maybe get in contact with gamebanana moderation or something, they'd probably help with that. If it's not okay, maybe could hire someone to make a program where you select your BK gamecube iso and it auto-rips all the files from it or something.MEGA or GoogleDrive will be good options indeed Helsionium! Especially MEGA.
I absolutely cannot WAIT to finally getting the remaster we fans deserve. Also cannot believe how fast you managed to do this. This is magnificant!
Hooray for such a dedicated fan!
