Homebrew developer Zx-81 is at it again, this time to update his PSP2600 for the Sony PlayStation Portable. Based on Bradfort Mott's Stella for PC, Zx-81's homebrew application is a port of the Atari 2600 emulator's version 2.2. PSP2600 version 1.1.2 has a hefty changelog that includes a bunch of sweet updates, such as an auto-fire mode and IR keyboard support.

Like the previous version, Zx-81 expects this one to be the last. Of course, if this is going to be the final build of PSP2600, the developer apparently intends to end with a bang. Aside from the additions mentioned, version 1.1.2 is optimized for better speeds, more accessible with hotkeys, and quick save/load is possible.

Here's PSP2600 version 1.1.2's changelog that may catch your interest:

• Auto-fire mode, press RTrigger+X to switch it on/off useful for games such as space invaders!
• On given games, the auto fire can't be stopped, so an option to stop it, is available in the settings menu.
• It uses now only PSP GU for rendering
• Speed improvements while using GU render modes
• IR keyboard support !
• Add .a26 as valid rom extention
• 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)

• RTrigger/LTrigger keys can be used in the keyboard settings menu to navigate between Normal, LTrigger and RTrigger compose mapping.
