-- Universal Cosmic games (Z80 based) for MiSTer - Mike Coates
--
-- V 1.00 - 03/07/2022 - Mike Coates
---------------------------------------------------------------------------------
--
-- Up, Down, Left, Right, Fire 1, Fire 2 (not all games use all buttons)

---------------------------------------------------------------------------------
This is a recreation of the Universal games that run on similar hardware
The game timing should be very close to the original, but the code is not
necessarily identical to the real thing, but achieves the same end result.
---------------------------------------------------------------------------------
Known differences / problems
Sound effects are implemented using samples (other than the DAC)
I have added a screen flip option to the sprite code, sprites are flipped by the
software on the real hardware, but everything else does have a flip signal. It is
implemented as a fake dip switch.
---------------------------------------------------------------------------------
Hiscore save/load
Save and load of hiscores is supported for Cosmic Alien only.
To save your hiscores manually, press the 'Save Settings' option in the OSD. Hiscores will be automatically loaded when the core is started.
To enable automatic saving of hiscores, turn on the 'Autosave Hiscores' option, press the 'Save Settings' option in the OSD, and reload the core. Hiscores will then be automatically saved (if they have changed) any time the OSD is opened.
Hiscore data is stored in /media/fat/config/nvram/ as "<mra filename>.nvm"
