Purpose

This working group is established to build libraries for the 6502 Atalan compiler, in order to streamline the programming of 8-bit content

Atalan compiler produces efficient 6502 code and is in active development. It specifically tailored for 8-bit game programming.

You can find more about Atalan at http://atalan.kutululu.org

State of development

• Atalan can now produce NES files, that can be directly used with FCEUX emulator.
• It is possible to create sprites and backgrounds.
• It is possible to read Input state of the Game-PAD's 
• Added support for 'in stream' registers like PPU_STAT_REG ($2002).

Goals

• Address joystick
• Address keyboard 
• Address PPU (Graphics Card) 
• Create some demos 

Scratchalan

Purpose

Scratchalan is module, that will allow creating a game in Scratch development environment (See http://scratch.mit.edu/) and generate Atalan source code,

that will then compile into NES cardridge image. For more information, contact Marcel Cevani at Atalan discussion group http://groups.google.com/group/atalan-lang. 

State of development

• Simple Controll blocks (loop,if,ifelse) and variable asigments are available
• Switching of background is now possible 
• Added more than one stage logic (for making intro screen,main , end etc) 
• Added new CommandBlock that alllows us to switch to a different stage 
• New minus block added 
• NES Specific Event blocks (Sprite Initialisation, Sprite Update, Sprite KeyPad Pressed)  are implemented
• Collision detecion with Bounding box (touch block) 
• Pressing the green flag will automatically start the ATALAN-Compiler and the resulting rom will be run in fceux emulator.
• Sprite defination files can now be imported.    

          If an preview File exist for it,its shown in the Sprite panel.

Next Steps

•   Adding more Controll-Block and adding Random number generator 
•  Testing... Testing 
•  Preparing beta package
