Xworld - Another World interpreter for Rockbox
Co-conspirators: Franklin Wei, Benjamin Brown
--------------------------------------------------------------------
This work is based on:
- Fabien Sanglard's "Fabother World" 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>
