As of 04-sep-2012, fceux supports this mapper correctly (r2648). The code was taken from fceu-mm which had some bugs related to missing reset logic. It is additionally supported by the Nestopia 1.40u4 hack. Mednafen also supports this mapper.
It is described as "DIS23C01 DAOU ROM CONTROLLER, Korea" and is used by the following games:
- Metal Force (K)
- Buzz and Waldog (K)
- General's Son (K)
- Koko Adventure (K)
The following description of it is based on FCEUX's implementation. It appears to fully-decode them, but that's probably inaccurate.
- PRG-ROM (16KiB switchable + 16KiB fixed-to-last banks)
- PRG-RAM (8KiB, the usual @ $6000-$7FFF, sometimes battery-backed?)
- CHR-ROM (8x1KiB banks)
- Mirroring (defaults to One Screen A; only written on General's Son?; once written, changes to V/H, or difference in hardware?)
