## Introduction



The Bandai WonderSwan is a handheld game console released and supported by Bandai from 1999 to 2003 in Japan. It is

the last piece of hardware which the legendary Gunpei Yokoi had a hand in.



It is important to note that WonderWitch development is distinct from bare metal WonderSwan development.

The former is specific to the WonderWitch - a special personal use development kit from Qute Corporation which came with

its own hardware abstraction layer and toolchain, while the latter focuses on outputting self-contained WonderSwan software.

As such, some of the tooling may not be applicable to WonderWitch developers.



## Documentation



### Datasheets



#### NEC V30MZ CPU



The NEC V30MZ is an 80186-compatible CPU for low-power platforms with an efficient pipeline design. It should not be confused with the

NEC V20/V30 line of CPUs, which provide additional opcodes and features on top of the 8086 architecture.



For a variety of reasons, NEC's documentation (and some WonderSwan documentation) uses unique NEC opcode names, while other sources

and assemblers typically use Intel opcode names. A translation map between the two is available [as part of STSWS](http://perfectkiosk.net/stsws.html#cpu_8086_translation_map).
