WonderSwan
Bandai's WonderSwan family runs a CPU compatible with 16-bit x86. Ghidra's x86 real-mode language reads it. Unicorn runs x86 16-bit code, so GameFrame's Unicorn emulator can run its functions.
The devices
| Device | Years | CPU and clock | Media and format | Ghidra support | Emulator with a debugger |
|---|---|---|---|---|---|
| WonderSwan, Color, SwanCrystal | March 1999 to 2002 (JP) | NEC V30MZ at 3.072 MHz | Cartridge | x86 real mode; ghidra-wonderswan | Mednafen, Mesen 2 |
Mednafen covers the WonderSwan with a debugger in its SDL front end. Mesen 2 covers the WonderSwan (system list not confirmed) (Mednafen docs; Mesen).

Hardware
The NEC V30MZ runs at 3.072 MHz and is compatible with 16-bit x86. The screen is 224x144 (WonderSwan).
Tools
Load the code with Ghidra's x86 real-mode language. ghidra-wonderswan adds a loader. The extension has few users, so test it on a known binary before trusting it.
For an exact reimplementation
Unicorn runs x86 16-bit code. Run single functions headless under GameFrame's emulator, as for DOS code (DOS games).
