TODO

Near future

• Check for zero pages when saving a state using /proc/self/pagemap flags
• Implement incremental savestates. Using the soft_dirty flag introduced in kernel 3.11, we can access to which pages have been written since a savestate was made, and only write the modified pages. It is performed by CRIU
• Input editor:
  • Show and edit analog inputs (mouse/controller axes)
  • Add copy/cut/paste features
• Restructure savefile handling to support renaming/removing files
• Fix savestates done on non-draw frames (need to save the return/register address from the altstack in the savestate and restore them when loading)
• Add tooltips to help the user
• Hook FMOD audio library

Not so near future

• Add hooks to Steam API functions so that Steam games can be launched without Steam opened
• Playing with the thread scheduler might add more determinism to multithreaded games
• Add the option to make certain threads to run synchronously, i.e. don't start the thread but call the function instead.
• Add to the state loading code the ability to stop and recover threads. It would need to build a correspondence table between game pthread ids and real pthread ids, and wrap every pthread functions that use the pthread id.
