Bootsector

The bootsector allowed an automatic startup (vs tapes) of games like in consoles with cartridges (of course a lot of games came also out as cartridge for computers). Put it in and switch on computer and play. Of course the bootsectorviruses were a sideeffect of this innovation.

Facts

  • TTV1 was the first file-based Amiga virus
  • Its creation was a fun experiment. It was inspired by the boot block based SCA virus which had reached dubious fame due to its very successful spreading and the flaw of overwriting the boot block. Would it be possible to create a self spreading file, thus breaking out of the boot block dread?
  • Development took place between spring and fall 1988.
  • The early code name was HOUZ virus.
  • Thinking up the name we tried to find something that would sound mean and at the same time on the verge to ridiculous. The final name was inspired by a rap band called The Terrorists.
  • The virus does not harm the system. In fact, care was taken to avoid any even unintentional damage.
  • Identity of the authors was kept secret for 30 years. It was officially revealed on March 9, 2019 at the Demonights 008 event in Bern Switzerland
  • "The names have been changed to protect the innocent" shown in the message was inspired by the song Beat Dis by Bomb the Bass. They have sampled it from the Dragnet radio series.
  • The "BGS9" was in fact a clone. Its code is almost identical even including the resident name "TTV1". It got more reach and thus was regarded as the origin.

About the life of the beast

  1. TTV1 installs itself as a reset proof resident module (KickTag/ROMTag) named "TTV1"
  2. On reset the resident module (virus) is called
  3. Execution gets delayed in order to gain disk write access. Therefore Intuition's OpenWindow function is redirected.
  4. As soon as the AmigaDOS tries to open the CLI window the OpenWindow gets called the virus looks for the startup-sequence on the booted disk
  5. The virus is looking for the first command (A) in the startup-sequence
  6. File request windows (e.g. "Disk is write protected") are being temporarily disabled
  7. Virus renames A to $a0202020a02020a020a0a0. This is a combination of none breaking spaces and spaces. The idea is that the user will oversee this "invisible" file.
  8. Virus writes itself as an executable command with the name of A to the disk
  9. Eventually A gets loaded and executed with all its parameters by the virus
The next time the user will boot the disk the virus gets loaded into RAM and step 1 takes place. On reset the horizonal beam position gets evaluated. If the beam position is smaller than a certain number the screen turns black and a message in white letters appears.

Antares is a classic role-playing game of the Bard's Tale variety set in a science-fiction scenario. After the radio contact with space explorers stopped, a second troop goes to look for them. Unfortunately on the way they receive a emergency call, get shot and have to land on the planet Kyrion. Now the troop has to explore the planet and find out more about what happened.

The party has six members (chosen from twelve pre-defined characters) with different statistics and abilities, e.g. fighting, cooking, PSI (the science-fiction variant of magic) or translating (needed to communicate with non-hostile species). The world and dungeons are explored through a first-person perspective and when meeting enemies, the fight plays out turn-based: the player tells the characters what to do and text informs of the results. Killing enemies reward experience points which in turn improve the abilities.

Each character has to eat and sleep. While too much hunger results in death, a sleeping character is in a kind of trance: he still walks around, but can't take any actions or fight. Besides sleeping, there is also medicine available to keep the spirits up: just like other parts of equipment, it can be bought in hidden shops with gold found at slain enemies. Each character can transport up to six items and a radar shows how dangerous the current area is. Dead party members can be resurrected at the landing module.
Market WAR

The Tandy Color Computer was the runner up. The Apple II was the winner in the category of home computer over $500, which was the category the Commodore 64 was in when it was first released at the price of $595.
n the United States, the greatest competitors were the Atari 8-bit 400, the Atari 800, and the Apple II. The Atari 400 and 800 had been designed to accommodate previously stringent FCC emissions requirements and so were expensive to manufacture. Though similar in specifications, the C64 and Apple II represented differing design philosophies; as an open architecture system, upgrade capability for the Apple II was granted by internal expansion slots, whereas the C64's comparatively closed architecture had only a single external ROM cartridge port for bus expansion.
Aggressive pricing of the C64 is considered to have been a major catalyst in the video game crash of 1983.
The price war with Texas Instruments was seen as a personal battle for Commodore president Jack Tramiel.[25] Commodore dropped the C64's list price by $200 within two months of its release.[6] I
Meanwhile, TI lost money by selling the TI-99/4A for $99.[26] TI's subsequent demise in the home computer industry in October 1983 was seen as revenge for TI's tactics in the electronic calculator market in the mid-1970s, when Commodore was almost bankrupted by TI.[27]
Although many early C64 games were inferior Atari 8-bit ports, by late 1983, the growing installed base caused developers to create new software with better graphics and sound.[34]

'After this period of demos, we started to work on a Point and Click adventure game, planned for PC, Playstation, and Linux called Immanis for the Cryogen label, a startup created in 1996. It was a superb project which never saw the light of the day due to questions around money and because the timing was wrong: editors and Publishers of the time didn't believe in Point and click adventures anymore.'

la1n was the direct next step from imp89. New maschines and a new platform macosx. “Therefore i learned objective-c and coded real object orientated” and switched now to 3d games with opengl. The games were now more an more like gameengines and were object-orientated. But still hardcore coded. This change with the upcoming game engine like torque or unity. 
Therefore the last games from la1n.ch till now were again hardcore coded games like axe (atari 2600 vcs), vecZ (vectrex 2016).

a qix/volfied variant of the game in 3d open gl. done in 3 months for a mac contest 2003 in us. there was even a radio event at 3 o clock than. won the 3rd price and a membership for one year in igda. the problem there was only one chapter in switzerland in berne with 3 members and never a meeting.

Floppy disc or magnetic disc are faster and mor flexible than tapes. you can load and store autonom (no start and stop) and not linear, you can store them here or there. but of course also expensiver (you cant anymore use a (music) tapedrive.
