The demo was created live at the Takeover'98 demoparty and features a bunch of 2D and 3D effects, all rendered in software.

The code was thrown together in 5 hours. Most of the time was needed creating the 3D meshes and getting my dusted-up prehistorik 3d engine to work. The music was the first tune in my Kork-music directory, so i timed the demo to it.

Release information

The demo was created for MS-DOS, but i've added a dosbox config + batchfile so it can be run from different platforms.

If anyone asks why i've wasted my teenage years behind a computer screen, cramped away in attics and basements? Well, here is the reason:

Logic Design was founded in 1994, as a cooperation by Flash, Balance and myself. Back in those days there were very few demo groups in the netherlands, so it didn't take much to get noticed. After a small intro for our BBS (LA Intro), we went on to create our first demo called Prologue which was released at the Bizarre'94 demoparty. While graphics may seem primitive today, mind you this was all done before 3D graphic cards, or even games like Doom were available.

In 1995 we were joined by Jace, another talented coder that we already knew before and lived nearby, as well as a new musician called Jenkins. That year we really stepped up our game with productions like the Spring! intro that was released at the X'95 demoparty and the demo Performance at the Bizarre'95 party. Both productions took first place in the competition. Until today, Performance is still my favorite Logic Design demo, as i think it best defines the quality and style of our team during that era.

In 1996 we were joined by Amiga legends Danny and Lowlife. This is also the year of our last production, called Fashion. The demo was released at the X'96 demoparty and also won the demo competition. Later that year the group split up and a part of the team joined the PC section of TBL.

To this day a still look back with a sense of pride at my Logic Design days. It ha s been a great learning school for us all and helped us in our jobs today in the game and multimedia industry. I still hang out with the other members of the team and we still have anual get-togethers.

Release information

If you are interested in our work from those days, i've compiled a package with our productions compiled with dosbox and easy-to-run batchfiles.

In 1990, i joined forces with a local coder called Flash to boost our coding skills. This resulted in many small games, intro's and demoeffects that we demoed at a local computer store, which also doubled as a meeting place. In 1993, we officially formed our first demogroup Chronic and Chrontro was our first and only proper release, before forming Logic Design early 1994.

Cavity is an arcade game for the Meggy Jr RGB (a 8x8 LED based handheld system).

Your goal is to navigate your way through the moving caves and collect the orange powerups for points. The game will gradually speed up to increase difficulty. The orange leds on top of the screen will indicate the speed.

Running the game(s)

You can use the avrdude tool to upload the hex-file. I've included a run168.bat/run328.bat (depending on your amtel chip) that does so using COM4 port. You can adapt the batchfile if you need to use another COM-port.

Alternatively, Windows users can also use the excellent ArduinoUploader tool by Vikas Patial that is supplied with this package. Here you can select the hexfile, chipset and com port.

I've also included stand-alone version for Windows systems, that runs in my MeggyJr simulator.

The Trip8/SuperTrip8 demo are demo's for the Chip-8 and SuperChip8 systems. The demo consists of an intro, 3D vectorballs, and 4 randomized dot-effects.

Writing a demo for the original Chip-8 interpreter was a real pain, since your framerate basically drops in half for every sprite you need to draw. So even clearing and redrawing a few dots will cause the framerate to drop to near zero :) Originally the demo was going to be bigger and there were much more graphical effects programmed/prototyped, but a lot of these effects turned out to be too much for the original unoptimized Chip-8 interpreters to handle.

Running the demo(s)

Use the Megachip emulator or any other Chip-8/SuperChip compatible emulator to run the demo.

The Climax Slideshow is a slideshow for the SuperChip8 system. It includes 6 different images drawn by a good friend of mine: Menno Seegers.

Running the demo(s)

Use the Megachip emulator or any other Chip-8/SuperChip compatible emulator to run the demo.

Release information

You can download the demo [here] I've adapted the images to work on a monochrome display and added the titlescreen. Due to the romsize limitation of 3.5kb, the slideshow is split into two parts.

Astro Dodge is an arcade game for the Chip8 and SuperChip8 systems. Both versions of the game are included in this package

Your goal is to make your way through the asteroids field and dodge the asteroids, scoring points for each asteroid you are able to dodge. Button 2,4,6,8 will move your ship, button 5 will start the game.

The MegaChip emulator is my Chip8/SuperChip/MegaChip8 emulator. It is the first emulator to support the MegaChip8 extensions, but ofcourse it also runs the Chip8 and SuperChip games

When developing this emulator, i also focused on something that annoyed me with other emulators: Every CHIP-8 game uses different keymapping, so it is always a pain to find the right keys which is especially annoying when using a console or handheld with fixed buttons. The MegaChip emulator does a CRC-check on the rom and adjusts the keymapping accordingly, so you have a more universal control scheme for each game.

Since i find it important to also support the original hardware (Cosmac VIP, Telmac 1800, ETI-660, etc.), you can switch between SuperChip emulation and the somewhat slower original CHIP-8 emulation on the fly using F11.

Features

- First emulator to support MegaChip8 emulation
- Switch between SuperChip and Classic Chip-8 emulation mode (Cosmac VIP, Telmac 1800, ETI-660,etc.)
- Emulates Hires Chip-8 mode (64x64) as supported by the original hardware
- Developer debugmode (Register info, program stepping,etc.)
- Automatic keymapping using CRC codes
- Different colorschemes
