The Teensy is in back order until November, whereas the Teensy++ is in back order until mid-September so I would go for the Teensy++ which is only a few bucks more and it's better than the Teensy. Plus would ship quicker as well.

As for your question, I am not sure, just pulling straws here, but maybe the .hex is a raw file, and which the Teensy Loader loads the .hex and programs the Teensy it may not actually be 33kb?

For example, the .hex may be the intructions the Loader needs to program the Teensy, where the program is smaller than the actual .hex.

thanks for the link, but it's not helping me (i'm not familiar with this technical language)

but i saw this : http://www.xboxhacker.org/index.php?...5206#msg115206

so i think it was a mistake to annonce the Teensy 1.0 (at90usb162) as psgroove compatible, isn't it ?

If you're "not familiar with this technical language", you should change forum, spreading your ignorance elsewhere or just wait for ready-to-use plug&play psjb solution.
Especially for you I've loaded the psgroove hex file to check it's size - the last occupied address is before 2EC0 (size < 11968 bytes). You can also add to this sizeof bootloader (usually < 4kB), which is still less than available 16k flash.
