Loader 2 Boot Tune via Piezo!!!

Contributor Joined: 26 Jul 2007

After playing around with Loader2's "ipod_beep", I added a "boot tune" function to Loader 2 which plays back a .pzm file generated by the piezo maker module.

The download below includes a modified loader.bin, a sample "boot.pzm" file (which Final Fantasy fans will recognize) and the patch file with the modifications (since Trac is down, as always).

Use ipodpatcher to install the bootloader (see the Loader 2 wiki page for instructions). Copy the "boot.pzm" file to your iPod (Loader 2 checks for a "boot.pzm" or "boot_tune.pzm" file in the same locations as it does with the kernel and loader.cfg file). Reboot your iPod and you'll hear your iPod's piezo (if supported) playback a nice tune.

If you want to play your own tune, you can specify the .pzm location in the loader.cfg file. For example:

Code:

boot_tune=(hd0,1)/FinalFantasyVictoryFanfare.pzm

You can create your own .pzm file using bmxr's piezo maker module or with fxb's Windows app.

Have fun!

WOW. This is... great!

/me uninstalls iloadz and installs this.

I can't put it into words! I love useless-but-cool features!

i had that same problem when i was tinkering withthe piezo stuff. but i managed to solve that problem by having it check for user inputs every few miliseconds, if it detected one, then it would stop the song. i dont have the source anymore, but i am just giving a small suggestion.

but great job! Very Happy

Thanks for the note. Loader 2 already has a keypad_getkey() function so I just added that check into my while loop. I also added a file existence check and searches for both "boot.pzm" and "boot_tune.pzm". "boottune.pzm" (or anything of filename length 12) doesn't seem to work for some reason though, even if explicitly specified in the loader.cfg file. This is most likely a vfs bug (but not really anything worth fixing).

Awesome! Make this like in the official loader2!
EDIT: Will this work with zeroslackr?

The bootloader is independent of the OF, iPL (whatever flavour), Rockbox, <insert any other "OS here>.

So yes.

hmm, does it check for the files in the same way the boot loader looks for .cfg files?

vfs_open (the call to open a file for reading) returns a -1 if the file is not accessible. I just use:

Code:

int f;
f = vfs_open (file);
if (f == -1) {
mlc_printf ("boot_tune file %s not found.\n", file);
return;
}

I just used pre-existing functions and didn't write anything new really.

zowki: Hopefully this will be added to SVN upon a bit of clean-up (*hint-hint-at-courtc*) and it only adds in 0.8KB more to the file size (most of which comes from the hard-coded file names) so it won't cause any issues. And yes, it will work with ZeroSlackr as for ZS I used an unmodified SVN-built loader.bin. I prefer useful changes to be committed up-stream rather than keeping it ZS exclusive.

Your multiple forum accounts are really confusing, why do you do it?
By the way I think you're a programmer god, you have worked on so much amazing stuff.

History. Too lazy to explain. If you just want a short answer, you could say that searching through posts by the "Keripo" account is far faster than searching through the useless comments of the "Keripo Test Account" account.

There are a lot of very-active devs out there far more worthy of that label (/me points to courtc, Exophase and the rest). I'm just a small fry doing end-user stuff. Wink
