My 11th very own custom Rockbox build for Sansa e200

My latest patched Rockbox build based on yesterday’s Revision 16718. As before it includes USB Mass Storage (High Speed), USB Serial, smooth resized Album Art, Viewports patches and Fast Charge. I also built a patched bootloader, which replaces the whole Sandisk bootloader decreasing the boot time to about 3 seconds (more than 10 seconds before)!SanDisk Sansa e200

I made this build to try the new bootloader and to see if the increased boost ratio I believe to get with the recent builds would drop.
The bootloader is working very fine! But you should be careful to take this step and be sure to read the patch tracker page. To apply the bootloader attach your Sansa to USB, be sure to unmount it, and use Sansapatcher (x86 binaries for Linux and Windows) like this: ./sansapatcher -bl bootloader.bin
High boost ratio seems to persist; though I’m not sure if it really increased. Maybe the higher boost is because of using the multiband equalizer now, instead of just the bass/treble settings like before or I simply don’t remember correctly. Should compare the boost behaviour with an unpatched build..
There haven’t been very grave changes in the codebase as far as I can see. There have been fixes to USB Storage, microSD hot-swapping, charging strategy, WPS tags. Additionally some DSP routines rewritten in ARM assembler.
