The wswan target provides support for targetting the Bandai WonderSwan console. In addition, experimental support is provided for targetting the WonderWitch abstraction layer.

Currently supported languages include:

• assembly - via binutils-ia16's GNU assembler, using Intel-style opcodes and syntax;
• C - via gcc-ia16, supporting up to the C11 standard with GNU extensions.

• Platform overview
• Known bugs

The wswan target features multiple subtargets:

• wswan/medium - create a ROM with multiple code segments, the default;
• wswan/small - create a ROM with one code segment, slightly faster code but 64KB maximum code limit;
• wswan/bootfriend - special subtarget for creating BootFriend executables which execute from RAM.

In addition, there exists an experimental wwitch subtarget for targeting the Freya abstraction layer.
