PS2 Moving games from USB to HDD?

[OilFreak]

I know it wouldn't be very fast at all, but trust me when I say that there is no good way to interface with an APA hard drive on Linux. My only Windows computer is a laptop with no SATA connectors and I rather don't feel like buying one.
How would one move a game in ISO format from a USB drive to the HDD? I know you just use uLaunchELF, but where in the file system should I put it? As far as I can tell there's no way to just browse the file system from OPL.

Disc images on APA aren't placed on any filesystem but injected into area dedicated to fs space. In other words: each APA partition with game, have normal Attributes area and FS area replaced by disc image. You cannot copy to/from such partition a disc image (mainly because on USB 1.1 this can take eternity, so no one ever make such application/feature) on PS2 side. Except from disc by HDLGame Installer (however DVD5 only).

Format drive as APA-Jail.

Well, I dare to not trust you. ;D

Oh, I stand corrected.
What I ended up doing last night was creating a full IMG backup of the drive, converting it to VHI, mounting it on a Windows VM, doing the deed, converting it back to an IMG, and restoring it to the drive. Hopefully this tool follows a less moronic process XD
