    Break-Out

    Break-Out

    The classical breakout game for hours of fun !

    This game is a nice remake of the traditional brick breaker game, which rules are the following. Bounce the little ball with the bar to destroy all the bricks. Try to survive all the levels to get a nice score or go as fast as you can to make the best chronos and be in the high-scores. Good luck ! If the game does not launch correctly, you probably have to install a more recent version of Java. I uploaded a light version of the game (without the soundtrack). Feel free to leave a review !

    achtbit

    achtbit

    An 8 bit emulator created on the scratch, including an assembler.

    Ever had the experience of a 8 bit system, having max. 64k memory, using assembler to write effective small programs? This system is an experimental 8 bit, 16 color computer, with a processer similar to Z80, that (on my laptop using linux with NO opengl support) achieves up to 1.2 Million instructions per second and 50 Hz. screen refresh rate. It has a builtin assembler to load assembler programs. There is a rudimentary rom that implements some basic functions like line input, or a system clock. Also there is a snake game, (depending on that rom), as a reference and for fun! Take a look, give me your reply! When having ideas for better performance, let me know!
