Download ZSNES 1.51

With ZSNES you can emulate a Super Nintendo Entertainment System under DOS, FreeBSD, Linux and Windows. Among other things, it mimics the following hardware of the SNES and its cartridges; the SPC700 sound chip, the SPC7110 data decompressor, the Super FX graphics accelerator, the Cx4 math coprocessor and the S-DD1 asic decompressor. The developers have released version 1.51 with the following announcement:

I’m pleased to announce the 73rd release of ZSNES – ZSNES v1.51. On the emulation side of things, we now finally have 224 lines displayed correctly, and some minor timing fixes. Major emulation core changes won’t be until a future release.

I would like to thank all those who reported bugs and sent in patches for v1.50, we’ve fixed roughly 3 dozen problems that cropped up with v1.50, including issues with loading older save states and various save state saving/loading problems , so this release should now be quite stable.

For SDL users who had sound issues before, we’ve made some fixes to that, as well as added support for libao sound output. Run configure with –enable-libao to get the new sound options compiled in. See zsnes –help for a list of drivers you can use. Feel free to play with each one and see which works best for you, there should be something to make everyone happy. Note however that certain older Linux versions have a bug in their threading which would cause all libao drivers to not output sound. If you’re having such an issue, install a new Kernel.

Also requested many times in the past was separate input for each game. I’m pleased to announce that with our new PSR language, adding this greatly desired feature was a cinch, so enjoy!

Lastly, people who have enjoyed the movie features with v1.50 should be happy to see that we’ve expanded them even more. For those of you dumping to raw or AVI, you’re now able to specify a logo file to use in the config file. You’re now also able to dump past the end of a ZMV.

And saving the best for last, there is now a custom multipass lossy dump option with decent default settings so you can dump really tiny good quality AVIs of your runs (and tweak dumping settings to your heart’s content in zmovie.cfg).

To those packaging releases for your distro, please see the notes for v1.50. Also make sure you review the configure options to provide the best build for your users. And please please include the documentation, located in docs/readme.txt and docs/readme.htm.
