In what is becoming a trend among homebrew developers, zx-81 is upgrading the supposedly final build of PSP2600 to version 1.3.3. Not that we're complaining, it's good that zx-81 is not settling for mediocrity for this Atari 2600 emulator.

Version 1.3.3 now includes eboot music from Observe & Control. zx-81 also rewrote many parts of the code for speed improvements. However, the changes done are not enough to play Pitfall 2.

zx-81 included the source code and mentioned that PSP2600 is bound by the GNU public license. For more information, be sure to check the readme first before doing anything
