well, your program is nice, except for two things.
1) it seems a bit more unstable, especially if the save settings partition is mucked with.
2) without usb mass support, or umcdr support, it's not very much use to me. currently i'm using launch elf usb mass to xfer files 16 meg at a time until i get a bigger flashcard.
I know you can't distribute umcdr enabled ps2menu-k, as that would go against drak's wishes but perhaps you can make a utility that could insert his irx, if someone has it (like me).
No don't ask me where I got it from. suffice it to say that it's no longer there, and you snooze, you lose.
