(incorrect header) and to support some more unlicensed Chinese games with fixed value registers as documented by Andlabs on the Sega Retro wiki
2017-03-29Allow games to be specified in ROM DB via sha1 instead of product ID. Added ↵Michael Pavone
a new ROM DB memory map device type fixed for emulating simple fixed value copy protection registers. Used those two features to support Ya Se Chuan Shuo via a ROM DB entry.

2017-03-21Don't leak a ternary tree when building the menu's initial pathMichael Pavone
2017-03-21Allow initial_path to contain variable references which allows the default ↵Michael Pavone
value to be actually specified in the default config file
2017-03-19Adjust Z80 interrupt pulse duration to match hardware measurementsMichael Pavone
2017-03-19Change handling of invalid scroll plane sizes. Fixes title and high score ↵Michael Pavone

sound after entering pause menu in Pacman 2: The New Adventures
