CaH4e3 updated his site with the following message:
- Queen Bee V (Unl)[!]. Let's continue. One of my long standing undemped carts from my Japanese frined Pongbashi. Queen Bee V by Nitra finally dumped. So sad it took so many time for dumping, even if mapper for this cart very good known a long time ago and have at least one more game working on it: "Time Diver Avenger" by the same Nitra. I don't even understand why previous attempts in dumping it has failed, but this time it took about 15 minutes to write mapper 250 dumping sequence and runit on my new hardware. Enjoy finally. You can play this dump on any known emulator, though.
