Upgrade Notes and Prerequisites

• The readme on GitHub has more instructions, and is usually more up-to-date than this page.
• Never mix different versions of BizHawk. Keep each version in its own folder.
• Windows users: Don't forget to run the prereq installer first!
  • Due to how BizHawk has evolved, earlier releases (1.x and 2.x before 2.4) might not work unless you also run an older version of the prereq installer.
  • BizHawk versions starting from 2.0 require a 64-bit OS. A "backport" release, 1.13.2, is available for users of Windows XP, 7, or 8.1 32-bit.
• Linux users: Distro-specific build instructions / packages are linked from the readme. A list of known bugs affecting the latest release can be found in issue #1430.

• Windows binary
• Released May 2, 2020
• Installation notes
  • Upgraded to .net 4.8, and c++ runtime deps have changed
    • Run the new prereqs installer
  • config.ini files from previous versions will no longer work

• New Core!
  • SubGBHawk - similar to SubNesHawk, allows for sub-frame movie recording support

  • update mgba to 0.8.1
  • Add memory callback support (debugger and lua)
  • Add trace logging support
  • Add input callback support
  • Support cpu register setting

• Gambatte
  • Many updates ported from upstream Gambatte through Gambatte-Speedrun to support the following:
    • Console accuracy for Pokemon TCG 1 and 2, now matching Game Boy Player when played as GBCinGBA mode
    • GBP console accuracy for Mickey's Dangerous Chase and other plain GB games that use LCDC interrupts when played as GBCinGBA mode
    • Maintain sync for all existing GBP console verified TASes
    • Pokemon Crystal (JP)
  • Ignore GBCinGBA setting unless console mode is GBC. GBCinGBA mode causes an edit to the GBC BIOS so that it matches GBA/GBP/GBI timings. If in GB mode this option is irrelevant.
  • A new palette mapping option "Libretro". The shader is an option in Extrems' GBI and in RetroArch. It accounts for non-linear colorspaces while doing the color mixing documented in Gambatte and in Libretro's shaders for the GBC LCD. See this thread for visual comparisons.
