 # Navigating the code
 
 ## Initialization
 
-[`4cade.a`](https://github.com/a2-4am/4cade/blob/master/src/4cade.a) is the main assembler target. It builds the launcher itself. Launcher code is split into code that can be run once from main memory then discarded, and code which is relocated to the language card and persists throughout the lifetime of the launcher. As the language card is only 16KB and will also need to store some persistent data structures, memory is precious and tightly managed.

-[`4cade.init.a`](https://github.com/a2-4am/4cade/blob/master/src/4cade.init.a) contains the code that is run once at program startup. First, we do some hardware detection, like how much memory you have, whether you have a joystick, and whether you have a IIgs. Then we relocate selected code to the language card and load the appropriate search index. (For example, if you do not have a joystick, games that require a joystick will not appear in search results.) [`constants.a`](https://github.com/a2-4am/4cade/blob/master/src/constants.a) has a rough map of what ends up where, within the language card and its overlapping memory regions. Then we load and parse the global preferences file ([`PREFS.CONF`](https://github.com/a2-4am/4cade/blob/master/res/prefs.conf)) and store the results in the language card. Finally, we jump to the main entry point (`Reenter`). The launcher is initialized; anything left in main memory is discarded.

 ## Search mode
 
-There are three major modes in the launcher: search mode, browse mode, and mega-attract mode. Search mode is the default, and it is always the first mode you enter when launching the program. [`ui.search.mode.a`](https://github.com/a2-4am/4cade/blob/master/src/ui.search.mode.a) tracks your keystrokes to determine the best match within the game list for the keys you have typed, then loads the game's title screenshot and displays the game name and other information at the bottom of the screen. If you have not yet typed any keys, it displays the title page and welcome message instead. The `InputKeys` table documents all other recognized keys.

 ## Browse mode
 
-The user enters browse mode by pressing the right or down arrow key. [`ui.browse.mode.a`](https://github.com/a2-4am/4cade/blob/master/src/ui.browse.mode.a) then watches for other arrow keys and displays the next or previous game in the game list.

 ## Mega-Attract mode
 
-If the user presses `Esc` from any other mode, or does not type anything for 30 seconds, the launcher goes into Mega-Attract mode, a.k.a. screensaver mode. [`ui.attract.mode.a`](https://github.com/a2-4am/4cade/blob/master/src/ui.attract.mode.a) manages loading and executing attract mode modules. An attract mode module can be a short slideshow, a self-running demo, or just a single screenshot. Modules are listed in [`ATTRACT.CONF`](https://github.com/a2-4am/4cade/blob/master/res/attract.conf) and are run in order until end-of-file, then it starts over from the beginning. The entire cycle is quite long (several hours), and some screenshots appear in multiple slideshows, but there is no actual randomness in selecting the next attract mode module.

However, not every game is playable on every device, so each record also contains metadata, e.g. "this game requires a joystick," or "this game requires 128K," or "this game has a double hi-res title screen" (which is not identical to "this game requires 128K").

 The format of the `GAMES.CONF` file has changed as new requirements have appeared, and it may change again in the future. There is up-to-date format information in comments in the file itself, which I will not duplicate here. However, in general, each record is 1 line and contains the name and flags for 1 game. The file is parsed during build and used to create the search indexes and other files which are stored on the final disk image.

 Attract modules are loosely divided into sets that have a loosely similar mix of hi-res, double hi-res, super hi-res, and self-running demos. The `ATTRACT.CONF` file is maintained by hand and changes frequently as we add games, split up slideshows, or reorder things on a whim.

Each record is a filename of a transition effect file, which is an executable file [assembled at build time](https://github.com/a2-4am/4cade/tree/master/src/fx) and stored on final disk image in a custom format. At the beginning of each slideshow, we query the global preferences to find the filename of the FX or DFX file, then update the global preferences with the next filename (wrapping around to the beginning of the list). If you watch the Mega-Attract mode long enough, you will eventually see all the transition effects, and since the cycle of transition effects is separate from the cycle of slideshows, you will eventually see the same slideshow with different transition effects.
