Changelog

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
mGBA

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.
