 ===== Users =====
+==== What is the WonderWitch? ====
+The WonderWitch is a personal software development kit developed by Qute Corporation for the WonderSwan and released in July 2000. It allowed users to create and publish their own independent WonderWitch-compatible games and applications.

 These items are useful, but not mandatory, to use the WonderWitch environment:
-  * A WonderWitch CD. Some proprietary files are contained on it which cannot be found online; this is of particular value if your goal is to develop, rather than only use, WonderWitch software - while open source toolchains for the WonderWitch exist, they are not as complete as the official kit and don't yet have as good documentation.

 Note that a PDF copy of the WonderWitch manual is provided on the CD, so you don't need to own it physically to have all the included material.

 ===== Developers =====
+==== What programming languages are supported by WonderWitch? ====
+Officially, assembly and C are supported for direct compliation; however, the community has enabled the use of other programming languages, like (old) C++ for direct compilation (via Turbo C++) or BASIC for interpretation (via WonBe).
 ==== Which compilers can be used with WonderWitch? ====

 ==== Can any 8086 compiler be used with WonderWitch? ====
-No. To support the WonderWitch architecture, a compiler must support the **small** memory model with **DS != SS** (data and stack segment differ). This is not a very common combination, as typically DOS applications used the same segment for near data and stack contents. It may also be possible, in some cases, to adapt **compact** memory model compilers.
+No. To support the WonderWitch architecture, a compiler must:
+  - not assume that **DS == SS** (under Freya, the data and stack segments are placed in different locations - data in SRAM, stack in IRAM). This is not a very common combination, as typically DOS applications used the same segment for near data and stack contents;
+  - support arbitrary **CS** (code segment) locations without relying on relocation - this, in practice, usually prohibits use of far code memory models.
