A new version of the Super Nintendo emulator bsnes has been released. Here are the major changes in version 0.108 according to the author:
This release brings in a 25% speed increase, optional frameskipping during fast forward (allowing an additional 33% max frame rate), official HD mode 7 support, SameBoy integration for 60% faster and more accurate Super Game Boy emulation, software filter support (snes_ntsc, HQ2x, Eagle, scanlines, etc), the return of mightymo's integrated cheat code database, cheat search support, movie recording and playback support, rewind support, cubic audio interpolation, 7-zip decompression support, ExLoROM board mapping support, adaptive sync support for OpenGL, and greatly improved macOS support. And if that's not enough, there's also true pixel-perfect ZSNES snow effect emulation ... seriously!
You can download the new version from the bsnes page. On this page you'll also find two new download links: the link for Nightly builds (with as-of-yet unreleased features) and the HD-mod, which improves graphics of "mode 7" games like F-Zero and Mario Kart. One of the Nightly builds (about SNES CPU overclocking) was featured in this Ars Technica article, while the HD-mod of bsnes was featured in an older Ars Technica article.
