UniPCemu build 2018/09/20 18:48 is now live!

Another smaller update, but with large stability and accuracy improvements!

Common emulator framework:

• PSP requires semaphores too for proper application functioning.
• Implemented multithreading safety by locking multithreading data using semaphores.
• Fixed thread.c code typo.
• Fixed multithreading.
• Implemented automatic thread cleanup.
• Improved terminated threads to be cleaned up better.
• Added the thread cleanup functionality to the threads termination functionality.
• Optimized thread cleanup.
• Replaced the entire thread pool used flag with the proper status bit.
• Fixed terminating threads and deallocating unused threads.

UniPCemu itself:

• Improved ET3000 vs ET4000 differences and compatiblity.
• Improved detection using the Segment Select register(always accessable).
• Improved ET3K/ET4K register protection to be complete.
• Improved handling of switching VRAM autodetection when changing video cards.
• Improved ET4K/ET3K memory size autodetect and size filters.
• Improved VRAM size redetection being applied correctly during restarting the emulator and applying new settings.
• Improved VGA memory needing to be a power of two to work properly and memory autodetect on VGA.
• Improved VRAM size safety checks.
• Improved ET3K/ET4K horizontal timings based on documentation.
• Improved ET3K double horizontal clocking on ET3000, according to documentation.
• Improved horizontal timings on ET3K/ET4K.
• Improved settings save detection, not saving unchanged settings.
• Simplified settings loading/saving only when starting/terminating the emulator.
• Fixed saving settings.
• Removed some unneeded settings saves during emulator startup.
• Fixed settings loading and saving.
• Allowed compiling signed PSP builds with the development kit, if supported.
• Improved free memory requirements.
• Fixed MMU code.
• emu_bios_post.c: Implemented logging of failed loading Option ROMs.
• Added logging of emulator reset loading ROMs.
• emu_bios_post.c: Improved POST and locks.
• Fixed graphics debugging to lock and unlock the main thread correctly.
• Fixed graphics debugging routine to properly release it's main thread lock.
• Updated the common emulator framework to the latest commit.

So in short, this bigger update contains:

• PSP versions have been fixed and signed, allowing running on any firmware.
• Multithreading has been improved and protected against multithreading operations(mostly affecting PSP crashes, which weren't protected from anything running multiple threads).
• ET3000 vs ET4000 accuracy improvements.
• Video memory size has been protected against strange values and proper automatic redetection when changing graphics card settings is now applied.
