bsnes-plus (or bsnes+) is a fork of bsnes (based on bsnes-classic) intended to introduce some new features and improvements, mostly aimed at debugging.

What's new

  • Improved debugger UI with register editing
  • Redesigned memory editor and breakpoint editor
  • Improved handling of address mirroring for breakpoints (extends to the entire address space, not just RAM)
  • Real-time code and data highlighting in memory editor, with fast searching for known code/data locations and unexplored regions
  • Cartridge ROM and RAM views in memory editor for mapper-agnostic analysis
  • Enhanced VRAM, sprite, and tilemap viewing
  • SA-1 disassembly and debugging
  • SA-1 bus and BW-RAM viewing and (partial) usage logging
  • Super FX disassembly and debugging
  • Super FX bus viewing and usage logging

Non-debugging features:

  • Satellaview / BS-X support
  • SPC file dumping
  • SPC output visualizer (keyboards & peak meters)
  • IPS and BPS soft patching
  • Multiple emulation improvements backported from bsnes/higan (mostly via bsnes-classic)

Development builds

Build status

Up-to-date development builds are available here (64-bit Windows, compatibility and accuracy profiles).

Building on Windows

  • Get mingw-w64 (make sure toolchain supports 64-bit builds)
  • Initialize the bsnes-plus-ext-qt submodule in git
  • Run mingw32-make

Building on OS X

Currently, OS X is not officially 100% supported. See this fork for now.

Building on Linux / other *nix

As there is no configure step, make sure necessary Qt5/X11 packages are installed. On a Debian/Ubuntu system, it would require a command like:

sudo apt install qt5-default qtbase5-dev-tools libxv-dev libsdl1.2-dev libao-dev libopenal-dev g++

Afterwards, run make and if everything works out correctly you will find the output binary in the out/ directory.

The snesfilter, snesreader, and supergameboy plugins can all be built by running make (or mingw32-make) after you've configured your environment to build bsnes itself. After building, just copy the .dll, .so, or .dylib files into the same directory as bsnes itself.
