Chui n'a clairement pas abandonné la Dreamcast et c'est tant mieux, un de ses message sur son blog :
Well, The goal of GENS4ALL for Dreamcast is emulate MegaCD at future but not 32X because we think that it is a similar work than do a Saturn4ALL but maybe at far future.
About NEO4ALL, we dont think about ISO+MP3 on SD-Card support at near future, now we are working an AES4ALL with SD-Card support first.
PCSX4ALL is working progress for CAANOO and Wiz now and Dreamcast version at near future, first with ISO support and next original CDROMs. I hope that first Dreamcast version will be released for this summer and a decent version for next Christmas.
Saturn4all could be after finish PCSX4ALL. Maybe for 2012?
