I have released DSLua 0.1 to public today.  The response has been positive.  I still have plenty of work to do before DSLua is finalized though.

Currently, it only supports some very basic text functionalities and input checking status.  Current version also only supports a few cards that Chishm's FAT driver supports (GBA Movie Player CF, SuperCard CF, M3 CF and Neoflash MK2/MK3).  Here is my todo list:

• add sprite/background/graphics support
• add sound support
• add music support
• file read/write support
• add GBFS support
• add network (TCP/IP & UDP) support
• better error reporting
• transfer scripts wirelessly and execute them
• support for other storage devices
• more documentations. Well, need to start one first
• more examples
• update Lua to latest version
• update libraries to the latest versions
• debugger/emulator to make it easier to develop/test
• allow edit and run scripts on DS

Please let me know how the preview version is working out for you. Thanks!
