byuu v3

March 19th, 2020, 18:03 Posted By: wraggster

byuu v3 is released. byuu is a multi-system emulator that focuses on accuracy and ease-of-use. It is currently in early release beta status. byuu is an upcoming multi-system emulator that aims to provide the accuracy of higan, with the ease-of-use of bsnes. It seeks to accomplish this by catering to the common 99% of use cases, rather than higan, which tries to cater to every niche. As such, certain advanced functionality will not be available in byuu; however, the emulator will be significantly easier to use, like bsnes.

Planned roadmap:
v1: support for gamepad mapping and the save state manager
v2: support for other controller types (mice, light guns) and multiple-players
v3: support for Famicom Disk System, Super Game Boy, and Sega CD emulation
v?: support for per-system input mapping, cheat codes, movie recording, and run-ahead functionality
v?+X: optional scanline renderers for each core to boost performance substantially
v?+Y: additional emulation cores from outside of higan (PS1, Saturn, N64 would be most promising!)
