fa3fc0c5c7 Commit FS #7379 - This patch fixes most of the sound problems from the previous version. This is a complete rewrite of VisualBoyAdvance's sound code from C++ to C. This patch also eliminates the need for some large tables giving more room in IRAM and the plugin buffer.

2882b26a99 Major Rockboy update.
1) Adapt Rockboy to smaller screens (H10, X5, and iPod Nano).
2) Add the ability to use a preset palette on color targets. Choose 'Set Palette' from the main menu.
3) Clean up the code to remove any unused code and variables.
4) Changed tabs to spaces.
5) Disable reading and writing sound when sound is disabled.
6) Disbable writing to the RTC since it is not implemented yet.
7) Minor optimizations from WAC gnuboy CE and iBoy.
8) Massive clean up of code to make it appear consistent.
9) Change all C++ style comments to C style.
10) Completely reorganize dynarec. Add fixmes to all unimplemented opcodes. Add debug writes for all opcodes. Attempt to implement a few opcodes myself.
11) Silence some warnings when built using dynarec.
12) Minor reshuffling of IRAM, may or not offer a speed increase.
13) Include fixes found in the short-lived gnuboy CVS.

All in all, there's about a 10% improvement on my test roms when sound is disabled and slight improvement with sound. Especially noticable when there are few sprites on screen and less action is occurring. See FS #6567.

137fb6cb9f Karl Kurbjun's patch #1407719:
Here's another patch for rockboy that adds automatic frameskip (it's pretty
rough as I haven't figured out an accurate timer), fullscreen support on the
H300, and a bit of assembly and some IRAM stuff. I'm not sure if I'm doing the
IRAM stuff correct though as it doesn't seem to make much of a difference if
any. I've also added a statistics option that will show how many frames per
second the gameboy is seeing (not what the player is getting) and what the
frameskip is at. When you enable stats sometimes you have to go back into the
menu and then come out to clear erronous values.

d2456b44f7 Centralised the ICODE_ATTR and IDATA_ATTR #defines. Renamed some musepack and rockboy headers to avoid clashes with rockbox headers.

384de10246 Rockboy - gameboy emulation for rockbox, based on gnuboy. Still a bit early, but already playable on iRiver H1xx and the simulators. The archos recorder version is currently rather slow...
