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
