A 48K Spectrum emulator port that was made for Linux/Windows, adapted to work on Nintendo DS. It was written with the following tools: devkitARM release 20, PAlib070717, Linker R4 DS. ==Features== * Full emulation of the 48K ZX Spectrum. * Support of snapshots files on SNA format. * Sound management. * Virtual keyboard managed with a Stylus. * SNA files browsing. * Joystick interfaces: Sinclair 1&2, Cursor and Kempston. * Automatic games set-up. * 50 FPS. * Possible loading of another ROM. ==Installation== Copy the bin/SpectrumDS.nds file to the root of your memory card. Then create a /sna/ directory at the same place as the binary and place the snapshot files in SNA format there. To facilitate the selection of SNAs in the emulator, you can place a screenshot of the game in this directory. This file must be in 128X96 pixels GIF format and have the same name as the sna file. Example: ChuckEgg.sna and ChuckEgg.gif ==User guide== ===Operation=== '''Top screen:''' * The top screen represents the Spectrum screen. '''Bottom screen:''' * In Spectrum mode, the bottom screen simulates the spectrum keyboard. * You will hear a clicking sound when you press a key. * Pressing the Start key allows you to access the SNA file loading and configuration panel. * To start a game, click on the image in the center. ===Configurations=== '''Config file:''' * It is possible to define a configuration file. * This file is used to define the interface to use joystick and define a sequence of keys to launch the snapshot. * The spectrum.cfg file must be placed in the /sna/ directory. '''Syntax:''' <SNA> <JOYSTICK> <SEQUENCE> <SEQUENCE>... * SNA - Name of snapshot file. Example: ChuckEgg.sna * JOYSTICK - Can take one of the following values. KEMPSTON, CURSOR, SINCLAIR_1 or SINCLAIR_2. * SEQUENCE- #<value> <key> ** <value>: Half-seconds to wait for each value. Example: #4 corresponds to a wait of 2 seconds. ** <key>: Name of the simulated key. '''Configuration example:''' <source lang="bash"> BountyBo.sna KEMPSTON #1 R #1 7 #1 6 #1 5 #1 8 #1 0 ChuckEgg.sna CURSOR #1 R #1 7 #1 6 #1 5 #1 8 #1 0 #1 S #6 1 ProjectF.sna CURSOR #8 3 #2 4 RollerCo.sna KEMPSTON TheAlche.sna KEMPSTON TheCoven.sna SINCLAIR_2 WizardsL.sna KEMPSTON </source> ===Tips=== * When launching the emulator for the first time, rather than selecting a snapshot, click on the icon at the top left. You will launch the Spectrum in basic interpreter mode. * You can activate/deactivate the automatic configuration by clicking on the Gear icon. * You can activate/deactivate the sound by clicking on the Musical Note icon. * Frames per second (FPS) can be displayed if you press the R button. ==Controls== Select - Change the joystick emulation interface Start - Access the selection panel SNA files and settings X - Shoot, Action D-Pad - Movement ==External links== * Author's website - http://buzz.computer.free.fr/index.php?post/2009/04/20/Emulateur-Spectrum-48K-pour-NDS
