Nice feature: Auto disc detection
The timeout feature is just great! If you just turn on your console, after the timeout ULF will boot your default prog (hdl, anyone?).
However, what would be almost perfect, would be an option to, boot from a regular cd/dvd (normal boot) if one is present, and if not, just go to the default selected option.
Since not all games are hdl compatible, some must still be played from dvd. And currently, if your default action is PS2 Disc, and no disc is there, nothing will load. However, is your option is boot, say hdl, and a disc is there, then the disc will be ignored.
Just an idea, doesnt seem that complicated.
Oh, btw, ULF (Unofficial LaunchELF) IS awesome, keep up the good work!
