Just when you thought the Atari 2600 was dead; ZX-81 once again reintroduces PSP2600 back into our lives… PSP2600 is the obvious PSP port of Bradford Mott’s Stella project. See the sourceforge project page if you’re interested in emulating the Atari 2600 on other platforms.

PSP2600 v1.2.0 changes:

• New graphics from my good friend Horeus (see http://www.ultimatepsp.fr/)
• New Eboot music (see http://www.jamendo.com/en/artist/pako)
• Cheat support (but it doesn’t work with all games)
• Finally fix issue with “Home -> Exit” !
• Add documentation for settings in help menu
• Improve file requester with virtual keyboard to choose sequentially rom files beginning with a given letter
• Text editor to write your own comments on games
• Display first comment line while browsing game files
• Add hotkey to change flicker mode
• Memory monitoring engine to find your own cheat code!
• Text editor to modify the global cheat.txt file
