# Building
|
||||
|
||||
In addition to _Contra_ (US), this repo can also build the _Probotector_ rom.
|
||||
To keep instructions simple, the section below only contains instructions for
|
||||
building _Contra_ (US).
|
||||
|
||||
If you are interested in building a _Probotector_ rom file, first read this
|
||||
section to understand what is needed, then follow the instructions in the
|
||||
section titled _Probotector_.
|
||||
|
||||
## Prerequisites
|
||||
* This repo does not include all assets (graphics data and audio data)
|
||||
necessary for assembling the ROM. An existing copy of the game is required.

|
|||
documenting the codebase. Every label had to be given an appropriate name, and
|
||||
each line of assembly had to be documented.
|
||||
|
||||
# Probotector
|
||||
This repo can also produce a _Probotector_ rom file. _Probotector_ is the
|
||||
PAL-specific variation of the _Contra_ (US) game. It is mostly identical except
|
||||
different sprites. For a full list of differences, see the document
|
||||
`docs/Probotector.md`.
|
||||
|
||||
## Building
|
||||
|
||||
First read the section above for building _Contra_ (US) in general. The process
|
||||
is very similar. Place a _Probotector_ rom in the root folder with the name
|
||||
`baserom.nes`. It should have a MD5 hash of `7127F616C13B58087481DD9E93AEB2FF`.
|
||||
|
||||
Then, depending on your environment, run one of the following commands.
|
||||
|
||||
| Environment | Command |
|
||||
|-------------------------|---------------------------------|
|
||||
| Windows | `.\build.ps1 -Game Probotector` |
|
||||
| Windows (no PowerShell) | `.\build.bat Probotector` |
|
||||
| Mac/Unix/Linux | `./build.sh Probotector` |
|
||||
|
||||
Notes of caution, especially for people building both _Contra_ (US) and
|
||||
_Probotector_.
|
||||
|
||||
1. Be sure you have the correct `baserom.nes` for the game you are building.
|
||||
Otherwise, the generated rom will be incorrect.
|
||||
2. If you have _Contra_ (US) assets in the `/src/assets/` folder and are
|
||||
building _Probotector_, or vice versa, the build scripts will delete the graphic
|
||||
asset data and re-extract it from the `baserom.nes`. This prevents accidentally
|
||||
using the wrong game's assets in the result rom.
|
||||

# Overview
|
||||
This file outlines the differences between _Contra_ (US) and _Probotector_.
|
||||
_Probotector_ is the PAL-specific variation of the _Contra_ (US) game. Note
|
||||
that all of the documentation that refers to code or look up table memory
|
||||
addresses were documented using _Contra_ (US) and may not be identical to the
|
||||
addresses in _Probotector_. All of the addresses that are used for game logic
|
||||
are the same. This includes pretty much any address defined in `constants.asm`.
|
||||
|
||||
# Differences
|
||||
|
||||
There are about 168 differences (#$a8 differences) between _Contra_ (US) and
|
||||
_Probotector_. Most of these differences are sprites.
|
||||
|
||||
## Logic
|
||||
|
||||
* When destroying all enemies (cleared screen, defeated boss, or picked up
|
||||
falcon weapon item), there is an additional check to not update the enemy to the
|
||||
"enemy destroyed" routine if its HP is 0. This check isn't done in _Contra_
|
||||
(US). This has no known effective difference in game play.
|
||||
* There is a useless execution of a function that does nothing but exit in the
|
||||
`check_for_pause` label.
|
||||
|
||||
## Audio
|
||||
|
||||
The helicopter sound is not played during the ending animation in _Probotector_.
|
||||
This is because the helicopter was replaced with a Jet.
|
||||
|
||||
## Background
|
||||
|
||||
* The introduction screen is completely different in _Probotector_. There is no
|
||||
scrolling introduction, and Bill and Lance have been replaced with a large
|
||||
PROBOTECTOR graphic.
|
||||
* The `level_8_supertile_data` is different between _Probotector_ and _Contra_
|
||||
(US). 3 super-tiles on the wall in front of the Alien Guardian (enemy type
|
||||
#$10) in Alien's Lair contain more well-formed shells in _Probotector_. The
|
||||
shells in _Probotector_ are actually retained from the super-tiles from the
|
||||
Japanese version.
|
||||
|
||||
## Palettes
|
||||
|
||||
A few palettes are different, causing the sprites to have been updated to use
|
||||
a different palette index to maintain the same color as the _Contra_. Some of
|
||||
the sprites are different colors due to the sprite changes
|
||||
|
||||
* Giant boss soldier's (enemy type #$13) spiked projectiles (enemy type #$14)
|
||||
were changed from blue to gray.
|
||||
* Enemy bullet color is red rather than white.
|
||||
* Dragon orbs (enemy type #$15) are red and blue rather than grey and red.
|
||||
* Ice grenades (enemy type #$11) are gray instead of blue.
|
||||
* Mining carts (enemy type #$14 and #$15) have black wheels instead of blue.
|
||||
* Flying capsules (enemy type #$03) on Alien's Lair are pink.
|
||||
|
||||
Player invincibility sprite palette pattern for player 2 alternates between red
|
||||
and gray instead of red and blue like in _Contra_ (US). In _Contra_ (US) both
|
||||
player 1 and player 2 flash between red and blue when have the B weapon.
|
||||
|
||||
## Text
|
||||
|
||||
* In the SPECIAL THANKS section of the credits, the to "AC CONTRA TEAM" has been
|
||||
replaced with "AC TEAM".
|
||||
* The location of various text on the game over screen and continue screen have
|
||||
been slightly moved
|
||||
* GAME OVER
|
||||
* CONTINUE
|
||||
* END
|
||||
* 1 PLAYER
|
||||
* 2 PLAYERS
|
||||
* Similarly, the introduction screen cursor locations have been updated to match
|
||||
the new location of CONTINUE/END.
|
||||
|
||||
## Sprites
|
||||
|
||||
Many of the sprites were changed to replace humans with robots.
|
||||
Additionally, some sprite animations were simplified, making many sprites
|
||||
identical, when they weren't identity in _Contra_ (US)
|
||||
|
||||
* `sprite_27`, `sprite_28`, `sprite_3c` are equal
|
||||
* `sprite_29` and `sprite_42` are equal
|
||||
* `sprite_3b` and `sprite_3f` are equal
|
||||
* `sprite_3d`and `sprite_3e` are equal
|
||||
* `sprite_93` and `sprite_94` are equal
|
||||
* `sprite_b7` and `sprite_b8` are equal
|
||||
* `sprite_bd` and `sprite_be` are equal
|
||||
* `sprite_cc`, `sprite_cd`, `sprite_ce` are unused in _Probotector_. However,
|
||||
they do exist and point to `sprite_cf` (ending animation islands).
|
||||
|
||||
To accommodate the player sprite changes, the initial location relative to the
|
||||
center of the player where bullets are generated have been adjusted (see
|
||||
`bullet_initial_pos_00`).
|
||||
|
||||
## Graphics
|
||||
|
||||
Below is the list of compressed graphics that are different. I haven't
|
||||
confirmed, but these differences are most likely just sprite pattern table tile

||||
