- square sine tick and tock sounds (more annoying, more useful;-)
- optical indication of tics on display
- unification of mode of operation for SWCODEC and HWCODEC (tested on simulator)
Both playback and display drawing happen in main loop, always.
- operating in two modes now:
-- 1. classic dumb metronome
--- active when openened as application without file to open
--- the usual functionality with tapping and bpm change
--- controls indicated on display
-- 2. track mode with programmable series of parts
--- active when started as viewer for a .tempo file
--- differing meters (4/4, 3/4, 6/8, etc.)
--- patterns (tick/tock/silence on each beat)
--- smooth tempo changes in those tracks
This version had lots of testing regarding metronome accuracy,
resulting in the realization that PLL A and PLL B differ
on the Clip+, causing drift. There is still drift when the timer
intervall is too small, so I settled on 2 ms as compromise.
This is the final version, after adding documentation and extensive
help from Sebastian Leonhardt testing it on slower hardware (YH820),
where it works up to 650 actual bpm with display indication.
Latest change: Documentation nitpicks.

This work is based on:

- Piotr Padkowski's newRaw interpreter which was based on
- Gregory Montoir's reverse engineering of
- Eric Chahi's assembly code

Progress:
* The plugin runs pretty nicely (with sound!) on most color targets
* Keymaps for color LCD targets are complete
* The manual entry is finished
* Grayscale/monochrome support is NOT PLANNED
- the game looks horrible in grayscale! :p
--------------------------------------------------------------------
Notes:
* The original game strings were built-in to the executable, and
were copyrighted and could not be used.
* This port ships with an alternate set of strings by default, but
can load the "official" strings from a file at runtime.
--------------------------------------------------------------------
To be done (in descending order of importance):
* vertical stride compatibility <30% done>
* optimization <10% done>

This is an improvement to the current compressor which I have added
to my own Sansa Fuze V2 build. I am submitting here in case others
find it interesting.
Features added to the existing compressor:
Attack, Look-ahead, Sidechain Filtering.
Exponential attack and release characteristic response.
Benefits from adding missing features:
Attack:
Preserve perceived "brightness" of tone by letting onset transients
come through at a higher level than the rest of the compressed program
material.
Look-ahead:
With Attack comes clipping on the leading several cycles of a transient
onset. With look-ahead function, this can be pre-emptively mitigated with
a slower gain change (less distortion). Look-ahead limiting is implemented
to prevent clipping while keeping gain change ramp to an interval near 3ms
instead of instant attack.
The existing compressor implementation distorts the leading edge of a
transient by causing instant gain change, resulting in log() distortion.
This sounds "woofy" to me.
Exponential Attack/Release:
eMore natural sounding. On attack, this is a true straight line of 10dB per
attack interval. Release is a little different, however, sounds natural as
an analog compressor.
Sidechain Filtering:
Mild high-pass filter reduces response to low frequency onsets. For example,
a hard kick drum is less likely to make the whole of the program material
appear to fade in and out. Combined with a moderate attack time, such a
transient will ride through with minimal audible artifact.
Overall these changes make dynamic music sound more "open", more natural. The
goal of a compressor is to make dyanamic music sound louder without necessarily
sounding as though it has been compressed. I believe these changes come closer to this goal.
Enjoy. If not, I am enjoying it

"Context Menu" when in the bookmark browser screen. This change makes %cs
return "Bookmark browser" when listing bookmarks from the context menu, the
same as when you list recent bookmarks. This change will make it possible
to determin that you are on a bookmark browser screen when skinning using

This port is a hybrid native/RaaA port. It runs on a embedded linux system,
but is the only application. It therefore can implement lots of stuff that
native targets also implement, while leveraging the underlying linux kernel.
The port is quite advanced. User interface, audio playback, plugins work
mostly fine. Missing is e.g. power mangement and USB (see SamsungYPR0 wiki page).
Included in utils/ypr0tools are scripts and programs required to generate
a patched firmware. The patched firmware has the rootfs modified to load
Rockbox. It includes a early/safe USB mode.
This port needs a new toolchain, one that includes glibc headers and libraries.
rockboxdev.sh can generate it, but e.g. codesourcey and distro packages may
also work.
Most of the initial effort is done by Lorenzo Miori and others (on ABI),
including reverse engineering and patching of the original firmware,
initial drivers, and more. Big thanks to you.

track is interrupted within the first 15 seconds.
Regard a rewind to 0:00 as a track restart (updating resume position /
playback statistics before the rewind and starting the 15 s delay).
This allows skipping forward across an unplayed track without changing
its resume offset. Also, it is possible to skip backward to the
previous track after rewinding to the current track to 0:00 (pressing
Left twice) without losing the current track's resume position.
Initially contributed by Dave Slusher
Caveats:
* Works only for SWCODEC
* Skipping forward without altering the resume position does not work
when skip to outro has been turned on.
* The 15-second window in which the resume offset will not be updated
should start at the initial resume position, not at 0:00. This
would allow skipping over partially played tracks without altering
the resume position.
