- 21st December 2007: Guru - A huge box arrived today. That 19.75kg box looks mighty impressive, although I'm not sure that all of it is going to be useful. Some could be alt. versions but most don't work so I'll need to dump all of these before I can tell exactly what they are. It contains Empire City (Seibu Kaihatsu, Taito/Romstar License 1986, orig.) and others. Thanks to Tingoes for sending these out.
