Today I've released a new version of my mega drive (genesis) emulator - sonic is even better :)
Had some fun doing the de-interlace coding - it supports bob and weave, as well as doing vertical filtering. Perhaps this is a bit over the top for an emulator, but it makes sonic 2 split-screen level nice and funky. If only it was within the bounds of possibility to do motion- adaptive de-interlacing, but I've never seen it done in software, and I don't think we have the processor power yet.
Last week I wrote an ftp client patch for openbsd so that you get a progress bar (well, the count bit) even when the file size is unknown, but gnats ate my email. Gah. I'll have to write the sendbug again :(
