Roudoudou released a brand new Zilog Z80 cross-assembler that targets the Amstrad CPC. Of course it supports all the undocumented opcodes, but beside of that, you can use conditional macros, a floating point engine and several mathmatical functions. A special feature is the possibility to create a cartridge for the Amstrad Plus or the Amstrad GX4000 directly by assembling your source code and you can automatically add an AMSDOS header to your binaries. However, it currently does not support the Maxam assembly syntax.
The latest version contains a lot of bugfixes (local labels, macro, label tree, alias, …) and a documentation in french and english. You can download and discuss it at the CPCWiki forums and at the end of this news.
