Homebrew legend Zx-81 has released another — PSPTI99 v1.0.3, the TI-99/4 emulator for PSP.

Changes:

• Speed improvements
• Add vsync and autofire options
• Add several new hotkeys:
  • settings such as fps, render mode, auto fire speed can now be directly modified inside the emulator (no need to enter in the settings menu)
  • quick save / quick load current state (no need to enter in the main menu)
• Default Hotkeys can now be set in the keyboard mapping menu (useful to add hotkeys on existing/previous keyboard files)
• Bug fix in the low battery watchdog
