 * BIOS controller functions for polling controller input work as intended
-  thanks to proper handling of hardware interrupts. No crude direct I/O polling
-  of controllers in the main loop.
-  
-* Complete Serial I/O support with SIOCONS driver for tty stdin/stdout
-  console access. Hardware flow control supported.
-
-* Full CD-ROM support using libpsxcd featuring data read, CD audio and XA audio
-  playback, built-in ISO9660 file system parser with no file count limit
-  (classic ISO9660 only, no Rock Ridge or Joliet extensions) and multi-session.
-  
-* Preliminary MDEC support implemented with libpsxpress (no VLC decoding yet).
-  Sample encoder included.
-
-* Can target Konami System 573 arcade hardware with limited support
-  (see examples/io/system573/main.c for details)
-
-* Experimental support for compiling separate sections of an executable into
-  shared library files (DLLs) and linking them dynamically at runtime, plus
-  support for function and variable introspection by loading a map file
-  generated at build time.
+  thanks to proper handling of hardware interrupts. Optional limited support

+* Complete Serial I/O support and console driver to redirect standard input and

 * Uses Sony SDK library syntax for familiarity to experienced programmers
   and makes porting existing homebrew projects to PSn00bSDK easier.

 ## To-do List
 
-* psxspu: Plenty of work to be done. Hardware timer driven sound/music
-  system may need to be implemented (an equivalent to the Ss* series of
-  functions in libspu basically). Functions that make use of the SPU RAM
-  interrupt feature to play or capture streamed audio should also be added.
+* `libpsxspu`: Plenty of work to be done. Some kind of MIDI sequencer (similar
+  to the one present in the official SDK) should be added at some point, along
+  with a proper API for audio streaming.
 
-* psxcd: Implement a command queue mechanism for the CD-ROM?
+* `libpsxcd`: Implement a command queue mechanism for the CD-ROM.
 
-* libc: Improve the memory allocation framework with multiple allocators, GC
-  and maybe helpers to manage swapping between main RAM and VRAM/SPU RAM.
+* `libpsxpress`: Add support for version 3 and IKI frame bitstreams.
 
-* Further support for MDEC, and tooling to transcode videos to .STR files
-  (either reimplementing the container and compression format used by the Sony
-  SDK, or a custom format with better compression).
+* `libc`: Improve the memory allocation framework with multiple allocators,
+  replace the string functions with optimized implementations and maybe add
+  helpers to manage swapping between main RAM and VRAM/SPU RAM.
 
-* Pad and memory card libraries that don't use the BIOS routines.
+* Add a full controller and memory card API that does not depend on the BIOS
+  controller driver, and possibly a library for interfacing to IDE/ATAPI drives
+  to make development for arcade systems easier.
