WonderSwan:WS Flash Masta USB
The FlashMasta is one of the oldest multirom flashcarts available for the WonderSwan. Instead of being microSD based, this cartridge has onboard storage and uses a microUSB cable to connect directly to your PC. It supports up to 16 slots for ROM files (The first game slot is usually reserved for the menu file so you can select more that one rom), and has one save file slot. Until recently, all games share the one save slot, meaning you lost progress when switching roms. But the new WSCartFriend menu automatically switches saves when changing games. This menu is experimental, but still recommended over the official menu.
Compatibility
Unfortunately, the FlashMasta does not have perfect compatibility with all WS ROMs. Below is a compatibility list pulled from the freeplaytech forums.
Due to hardware limitations, the following roms from GoodWSx v3.27 do not work with the WS Flash Masta v5.1:
