Amiga software is computer software engineered to run on the Amiga personal computer. Amiga software covers many applications, including productivity, digital art, games, commercial, freeware and hobbyist products. The market was active in the late 1980s and early 1990s but then dwindled. Most Amiga products were originally created directly for the Amiga computer (most taking advantage of the platform's unique attributes and capabilities), and were not ported from other platforms.
During its lifetime, thousands of applications were produced with over 10,000 utilities (collected into the Aminet repository). However, it was perceived as a games machine from outside its community of experienced and professional users. More than 12,000 games were available.[ 3][ 4] New applications for the three existing Amiga-like operating systems[ 5] are generally ported from the open source (mainly from Linux) software base.
Many Amiga software products or noteworthy programs during the timeline were ported to other platforms or inspired new programs, such as those aimed at 3D rendering or audio creations, e.g. LightWave 3D, Cinema 4D, and Blender (whose development started for the Amiga platform only). The first multimedia word processors for Amiga, such as TextCraft, Scribble!, Rashumon, and Wordworth, were the first on the market to implement full color WYSIWYG (with other platforms then only implementing black-and-white previews) and allowing the embedding of audio files.

History and characteristics
From the origins to 1988
Amiga software started its history with the 1985 Amiga 1000. Commodore International released the programming specifications and development computers to various software houses, prominently Electronic Arts, a software house that then offered Deluxe Paint, Deluxe Music and others. Electronic Arts also developed the Interchange File Format (IFF) file container, to store project files realized by Deluxe Paint and Deluxe Music. IFF became the de facto standard in AmigaOS. The first to be shown were digitizer software ProPaint (in early beta). Both were used by Andy Warhol to produce a black-and-white photo of Debbie Harry at the Launch Gala at Lincoln Center, New York City in July 1985. In 1985 Commodore licensed the software called Transformer from Simile Research and put it on the market in January 1986, bundled with an external A1020 5.25-inch floppy drive. It emulated 8086 Intel-based PC-XT hardware. It could run MS-DOS and MS-DOS software such as Lotus 123 or WordStar. This provided early access to many applications, while waiting for native Amiga software to be developed. In 1985, Deluxe Paint emerged with graphic features that had been available only on dedicated graphic computers. It was dubbed the first Amiga "Killer application".
In 1986 (the year of the launch of Amiga 2000) Amiga software products contributed to the Amiga's success as a game and multimedia machine. AmigaBasic from Microsoft, VizaWrite, TextCraft (word processors), Pagesetter (Desktop Publishing), Analyze! (Spreadsheet), Superbase Personal (Database), MovieCraft (animation), Deluxe paint II, Deluxe Music, Instant Music (a composition music program for non musicians) from Electronic Arts, and GraphiCraft again from Commodore were released. GraphiCraft was used by computer artist Jim Sachs to produce Amiga software such as Defender of the Crown and Centurion: Defender of Rome from Cinemaware and the Amiga porting of Saucer Attack. Graphicraft was a predecessor of Aegis Images and AEGIS Animator, one of the first programs worldwide capable of creating animation videos and cartoons complete with audio stereo, featuring a cel animation working paradigm interface and outputting files based on delta-frame difference compression method which then were the lead for creating the ANIM file type standard. Byte-by-Byte Software Inc. released Sculpt-3D. It was the first rendering tool available for the first time to a vast audience of public, and in October of the same year, Impulse released TurboSilver.
In 1987 the Amiga 500 (A500) was released. The Amiga software market moved in favor of entertainment over professional software.
In July, Wordperfect created an "Amiga/Atari Division" and started selling a version of its word processor for the Commodore platform for US$400. It could load and save Wordperfect files created on any platform, such as IBM, Macintosh and Apple II. Wordperfect 4.1 for the Amiga was the first word processor in the world capable of opening an unlimited number of documents (limited by RAM), each in a separate window.
In 1988, Photon Paint was released. It allowed digital painting using HAM graphics mode and the full 4096-color palette of Amiga on a single screen. Maxiplan 500 become Maxiplan 1.x, Electronic Arts showed DeLuxe Photo Lab (photo editing software), Newtek demonstrated DigiView 3.0 hardware and software image digitizing suite, and WordPerfect released the WordPerfect Library for the Amiga. At the summer Consumer Electronics Show (CES), the Pro Draw graphic tablet with mouse emulation software was also announced, as well as Flash-Back and Quarterback hard drive backup software. Superbase Personal became Superbase Professional, Micro Illusions started shipping Music-X audio software for the Amiga, and Lattice released its C++ preprocessor for the Amiga. Cygnus Editor ubiquitous text editor, one of the most versatile text editors and best seller on Amiga since then, was also released this year. It was one of the first Amiga programs featuring an AREXX port. Gold Disk released ComicSetter (comic creation) and MovieSetter (32-color cartoons with stereo sound animation software). In November, at the World of Commodore Show, ReadySoft demonstrated its Amax Macintosh emulator for the Amiga.
In 1989, Rashumon was first launched. In 1990, AmigaDOS 2.0 was released. The interface of the Workbench GUI was changed to a fake 3D aspect using gray shades. For the first time, Commodore introduced a style guide for developers on AmigaOS; because of this, the majority of Amiga software developed for AmigaDOS 2.0 had a standardized GUI that improved usability. Programs such as Imagine 3D, Lightwave, ImageFX, and Scala continued using non-standard GUIs. AmigaVision was released and bundled free with any model of Amiga 3000. Directory Master, Directory Opus, TurboCalc, Photogenics, ImageFX, PC Task, Photogenics, Caligari, Final Calc, and Cinema 4D all belong to this period.
1994 to today
After 1994, Commodore's demise left Amiga to an uncertain future. Windows-based PCs became the standard in the home and the office. Many software houses either left the Amiga market or ran into financial troubles. In 1996, Aminet was created. Aminet was the first centralized Internet repository of all Amiga public domain software and documents. It was the first Internet experiment of a centralized software repository created and maintained by one community for the community itself. Amiga's browsers like AWeb, IBrowse and Voyager were enhanced. Voyager was the first browser to adopt tabbed browsing. Mailers like YAM are still used. In productivity software, programs like Candy Factory for image processing were still being developed, for vfx and animation programs like Wildfire by Andreas Maschke (ported by author to Java later). other prominent graphic software include fxPAINT by IOSpirit, fxSCAN for OCR and scanning by IOSpirit, and SketchBlock painting program by Andy Broad for AmigaOS 4.x. Last but not least Tornado3D raytracing program by the Italian company Eyelight.
Amiga software presents a complete graphical interface, following Amiga WYSIWYG "desktop paradigm" and native AmigaOS interface guidelines; that is to say, the software is mouse-driven and presents also pull-down "menus" and "dialogue windows". AmigaOS maintained a text-based shell allowing software to present a text-based GUI, or a "command line".
The main software categories are
- Productivity software (also called application software);
- Support and maintenance utilities for formatting hard disks, recover or backup data, etc.;
- Multimedia software (graphic, video, music);

In some European countries, and especially in France, Minitel data transmitting services were popular before the Internet. Minitel had many consumer-level communication services, including chatting, email, railway and broadcast timetables and travel and hotel booking. Minitel used little terminals rented from telephone companies or computers with modems that accept Minitel transmission protocol speed. Amiga Minitel communication programs were written in France, Germany and Italy (Amiga Videotel).

Skypix is an Amiga communication protocol. It was one of the first interactive online graphics-and-sound protocols. It was introduced in 1987 as part of the Skyline (Atredes) bulletin board system (BBS), running on the Skyline BBS and Skyterm terminal. Years before the World Wide Web, Skypix allowed rich interactive graphics and sound, as well as mouse control, to be a part of the online experience, which was until then limited to text and ANSI graphics. Skypix allowed users to write and integrate graphical programs, and included the first "authoring program", Skypaint. Skypix created enthusiastic game and online application writers years before the World Wide Web made such features a common part of the online experience. It was quickly abandoned as more advanced markup languages for BBS became available and due to the emerging of Internet phenomenon that marginalized the BBS system of communication.
Despite the variety of programming languages and compilers, most development was done using C and C++, 680x0 assembler and various Basic dialects.

AmiDock creates application launching docks on the desktop. It became popular in 1989–1990, due to the NeXT computer, that used the same 68030 processor as Amiga 3000) and that it also had the Acorn Archimedes RISC OS docking station utility. In Great Britain, Archimedes computers were adopted in schools. Young Amiga users (there were 1,500,000 Amigas sold in the United Kingdom) spotted docks on Archimedes at school and asked for it on Amiga also. Various launch bars or docking utilities were born as third-party hobby utilities (many examples of early docking software for Amiga like the ToolManager are still hosted in the Aminet repository of all Amiga free software, in the "Utility" directory) and then Amidock was officially integrated in AmigaOS with version 3.9.
Directory Opus was a file utility program. When this software was released, Amiga magazines[clarification needed] proclaimed that it was the most important software ever released for the Amiga and "should be built into the operating system". Directory Opus went on to create a "replacement OS" for Workbench which overlaid itself upon the system. It started as a file manager, and then became a complete desktop replacement and an alternative to the official Workbench. The utility was later ported to Windows and remains widely used.
HyperCache was the first commercial disk caching software. Significant in that the base operating system lacked this ability, the addition of caching significantly improved the performance of both floppy and hard discs.
Much shareware and free software was written for the Amiga and could be obtained via the Fred Fish disk series or from the Aminet software archive.
Because the custom chipset shares RAM (and therefore the memory bus) with the CPU, throughput increases measurably if the display is disabled. Some processor-intensive software, such as 3D renderers, disable the display during calculation to gain speed.
Notable emulators included:
Medusa (Atari ST emulator), Fusion (Macintosh Emulator), AMax and AMax II, (Macintosh), GO64 (first Commodore C64 emulator), Transformer and PCTask (it was an Intel 8088 emulator, all software based, capable to emulate Intel PC based platforms ranging from PC XT 4,7 and 7 MHz on Amiga 500, up to 80486 running at 12 MHz on Amiga 4000 and other accelerated Amigas), A64 Package (C64), Amiga BBC Emulator (Acorn BBC emulator)
Atari ST Emulator (AtariST), Hatari (Atari ST and STE), Basilisk II (Macintosh) classic, Frodo (C64), PSXE (Sony PlayStation), Hu-Go! (PC Engine, TurboGrafx-16), FunnyMu (Creativision, Funvision, Wizzard), AmiArcadia (Arcadia 2001 and VC 4000, TVGC).
VICE emulator is modular and emulates all 8-bit machines made by Commodore: C64 (a patch of VICE supports C64dtv), C128, PET including CBM II version (but excluding "non-standard" features of SuperPET 9000), Plus4 and VIC-20.
Thousands of games were produced. At the time it was common for games to be produced for multiple formats. Since the Amiga hardware was the most advanced, games were usually developed on an Amiga, and the Amiga version would be the "gold standard" of the bunch.
The Amiga was a focal point for the "demo scene". The Amiga thrived on public domain, freeware and other not-for-profit development. The demo scene spearheaded development in multimedia programming techniques for the Amiga, such that it was de rigueur for the latest visual tricks, soundtrackers and 3D algorithms from the demo scene to end up being used in computer game development.
Because Amiga was one of the first game-oriented computers to feature a built-in floppy disk drive, it simplified software piracy. Many of the arguments pertaining to software copying, intellectual property rights in software, the open-source movement by the early 1990s.[clarification needed] It was not unusual for demo groups to be openly involved in software piracy.
Anti-piracy measures included the practice of distributing software on disks that contained secret "keys" on high-numbered tracks that were officially unused. The Amiga disk drive officially supported tracks 0–79 from a double-density disk, but could actually read tracks 80 through 82. Standard disk-imaging software ignored these tracks, so that a duplicate of a boxed disk would not contain the key and the software would not work. A similar technique involved writing to normally-unused sectors of the disk. Copy software called "nibble" copiers appeared that could exactly reproduce such disks.
Publishers turned to other methods. Hardware dongles were occasionally used for high-end software. AmigaHASP protected Rashumon and was sold by HarmonySoft to Aladdin Systems. Some software manufacturers asked users to type a word from a particular page number and line number of the manual, meaning that successfully copying software included photocopying a large quantity of text. Sometimes the text was designed so that photocopiers would produce illegible copies, meaning that pirates had to manually add the text.
Pirates responded with "cracking" software that altered the code to bypass copy protection completely. Every protection scheme was eventually broken. One near exception was the scheme on Dragon's Lair, which became the "holy grail" of crackers worldwide, but it was also broken.
The Amiga's floppy disk drive allowed 880 kilobytes on a single disk, comparable to the RAM of most Amigas (512 kilobytes to 1 megabyte). To increase capacity, Amiga used data compression. The disk drive had a slow transfer rate, such that using processor-based decompression could actually reduce loading times versus loading uncompressed data. Early implementations wrote to a video display register, causing it to break into multiple segments of colorful noise, which would become finer as the decrunching continued. This effect was psychedelic and very easy to implement, so it stuck; it was pioneered on the Commodore 64.
