Controls: Movement: Joystick, Keyboard(Arrow Keys) Buttons: 1-4 on Joystick Fire Buttons (Player 1) 1-4 on Keyboard 1-4 and WASD (Player 2) NUM, /, *, - on Numpad and Arrow Keys

ToDo: Reset (hold Button longer for a Correct Reset)

-- DE10_lite Top level for vectrex by Dar (darfpga@aol.fr) (27/12/2017) -- http://darfpga.blogspot.fr

-- Educational use only -- Do not redistribute synthetized file with roms -- Do not redistribute roms whatever the form -- Use at your own risk

-- Use vectrex_de10_lite.sdc to compile (Timequest constraints) -- /!
-- Don't forget to set device configuration mode with memory initialization -- (Assignments/Device/Pin options/Configuration mode)

-- TODO : -- sligt tune of characters drawings (too wide) -- tune hblank to avoid persistance artifact on first 4 pixels of a line

-- -- Main features : -- PS2 keyboard input @gpio pins 35/34 (beware voltage translation/protection) -- Audio pwm output @gpio pins 1/3 (beware voltage translation/protection)

-- Uses 1 pll for 25/24MHz and 12.5/12MHz generation from 50MHz

-- Horizontal/vertical display selection at compilation -- 3 or no intensity level selection at compilation

-- No external ram -- FPGA ram usage as low as :

-- 336.000b ( 42Ko) without cartridge, vertical display, no intensity level (minestrom) -- 402.000b ( 50Ko) with 8Ko cartridge, vertical display, no intensity level -- 599.000b ( 74ko) with 32Ko cartridge, vertical display, no intensity level -- 664.000b ( 82ko) with 8Ko cartridge, horizontal display, no intensity level -- 1.188.000b (146ko) with 8Ko cartridge, horizontal display, 3 intensity level

-- Tested cartridge:

-- berzerk ( 4ko) -- ripoff ( 4ko) -- scramble ( 4ko) -- spacewar ( 4ko) -- startrek ( 4ko) -- pole position ( 8ko) -- spike ( 8ko) -- webwars ( 8ko) -- frogger (16Ko) -- vecmania1 (32ko) -- war of the robot (21ko)

-- Board key : -- 0 : reset game

-- Keyboard players inputs :

-- F3 : button -- F2 : button -- F1 : button -- SPACE : button -- RIGHT arrow : joystick right -- LEFT arrow : joystick left -- UP arrow : joystick up -- DOWN arrow : joystick down

-- Other details : see vectrex.vhd -- For USB inputs and SGT5000 audio output see my other project: xevious_de10_lite

-- Use tool\vectrex_unzip\make_vectrex_proms.bat to build vhdl rom files
