Some Super Famicast news has been posted by scherzo in this forum post, a new release may not be too far away:
“I finally got it to work. Right now, it only works with sound enabled. If I disable sound, most games don’t work or have graphical errors. The speed is definitely better but still a bit short of DreamSNES with sound. I’m curious how much faster it is with sound disabled. This is a start though.
Looking at the assembler gives me much insight about how to write SH4 asm. I should be able to use it as kind of a tutorial to write other parts in assembler.
I’m going really to bust my ass to make a release this weekend. Talk to you all later.“
