The WonderWitch is an official homebrew development kit released by Qute Corporation on July 18th, 2000.
The WonderWitch cartridge is based on the Bandai 2003 mapper. It provides an RTC, as well as NOR self-flashing functionality using the Fujitsu MBM29DL400TC chip.
There were three ways available to acquire WonderWitch cartridges:
- WonderWitch, a software development kit containing a reflashable cartridge, a WonderSwan<->RS-232 adapter, a development manual and a development tool CD;
- WonderWitch Player, a priced-down user-only version omitting the development manual and tooling;
- The VAR program, allowing independent creators to buy reflashable cartridges in bulk, in units of 20 or 100.
The 512KB of NOR flash memory is mapped and partitioned as follows:
