-- U(U) : auto/up (!manual/down)
-- H(H) : high score reset
--
-- To enter service mode press 'advance' key while in game over screen
-- Enter service mode to tune game parameters (difficulty ...)
-- Tuning are lost at power OFF, for permanent tuning edit/set parameters
-- within defender_cmos_ram.vhd and recompile.
--
-- Other details : see defender.vhd

Required ROMs (Not included)
-----------------------------
You need the following 14 ROMs binary files from defender.zip
(MAME defender)
defend.1, defend.2, defend.3, defend.4, defend.6, defend.7
defend.8, defend.9, defend.10, defend.11, defend.12
decoder.2, decoder.3
defend.snd
------
Tools
------
You need to build vhdl files from the binary file :
- Unzip the roms file in the tools/defender_unzip directory (or win32 or linux)
- Double click (execute) the script tools/defender_unzip/make_defender_proms.bat to get the following files
The following 14 files will be converted to vhld (rom) files.
defend.1 + defend.4 +
defend.2 + defend.3 +
defend.9 + defend.12 +
defend.8 + defend.11 +
defend.7 + defend.10 +
defend.6 => defender_prog.vhd
decoder.2 => defender_decoder_2.vhd
decoder.3 => defender_decoder_3.vhd
defend.snd => defender_sound.vhd
*DO NOT REDISTRIBUTE ANY OF THESE FILES*
VHDL files are needed to compile and include roms into the project
The script make_defender_proms.bat uses make_vhdl_prom executable delivered both in linux and windows version. The script itself is delivered only in windows version (.bat) but should be easily ported to linux.
Source code of make_vhdl_prom.c and duplicate_byte.c is also delivered.
---------------------------------
Compiling for de2
---------------------------------
You can build the project with ROM image embeded in the sof file. DO NOT REDISTRIBUTE THESE FILES.
3 steps
- put the VHDL ROM files (.vhd) into the project directory
- build defender_de10_lite
- then program defender_de10_lite.sof
