This information is superseded, see Sachen Mappers. I thought I might as well update that within hours of opening my 4B-007 cartridge I managed to dump it.

So I recently acquired a Sachen game, 4B-007 “4 in 1”. Of course, I had to open it somehow to look inside… Cartridges are a bit smaller than regular Game Boy cartridges and they lack a screw at the back. So with no easy way to open it and prying… Read more »

So I’ve been somewhat busy tracking down some unconfirmed Gameboy cartridges from the no-intro set. Glad to say that right now only German Pokémon Yellow is missing from German DMG games 🙂 Have some other games in store I dumped and forgot about, but will commit them to DoM soon… Read more »
Yeah, so I uh.. procrastinated a little with everything here 🙁 Anyway, I totally had time today to fix some things up on this site, but as you can see, still no magic header image rotation 😐 I was busy doing important™ stuff™ for university, like working towards my M.Sc…. Read more »
