One thing that makes MSX great is BASIC, the programming language that is accessible for all. To promote MSX-BASIC we are going to post some minis. Small parts of basic code that can be handy for making games or tools.

Most can be found in the many books written about MSX-BASIC, but sometimes it is easier to see a example.


The first will be about how to use mouse input.



20 X=255: Y=107: PSET (X,Y),0

30 IF PAD(12)=0 THEN GOTO 30

40 X=X+PAD(13)

50 Y=Y+PAD(14)


70 LINE -(X,Y),P,B

80 GOTO 30


We took some images of or msx collection.

It is a fascinating screen that is not used a lot on MSX. On MSX2 I once made some animations from gif to MSX.

It was a lot of work to set the correct palette for each frame.

Still progress on the game Petra.The game is made in Screen 8(256×212 256 colors), so the Darkstone logo should be also.


This Youtube movie shows part of the game play of the upcomming game : Petra



Part of the intro image is made. The ‘player’ is done. now we need to draw her to game size.

At the Bonami fair, Darkstone will show a first live peek of their upcoming game!

Darkstone's wip game

The 24th Bonami fair takes place from 10:30 to 15:30 on September 27 in Matenpark, Heemradenlaan 130, Apeldoorn. The entrance fee is 4 euros.

In celebration of Bonami computer and game museum opening a new location, Darkstone has donated a wall painting.
Most people will recognise the concept of the game depicted in the artwork, which looks a lot better in real life.
Checking out the wall painting would not be the only reason to visit the museum though, it has 3000m2 of computers,
consoles and arcade cabinets to enjoy!



Drawn on msx in paint4.

MSX: Sony HB-f9P inc. Nowind, sony hitbit mos-1 mouse , 21″crt

Total 10 hours of drawing.

The Darkstone site has received some minor styling updates, amongst which a new background image and improved legibility. The ‘darkstones’ on the background are based on the Charred photograph by Filip H.F. “FiXato” Slagter. The original is available for licensing.

This Sunday, on the 29th of September, Bonami is organising their usual retro computer fair in Apeldoorn again, and it will be bigger than ever.

Of course Darkstone will be attending as well, and to make it easier for you to spot our booth, we’ve had a new banner made for us:

Darkstone will be easier to spot from afar now with this new banner

Sometimes drawing in a certain style takes too much time and effort to create enough levels for an entire game.

For example the graphics that Lord Zett drew for a possible Darkstone project.

Below you can find “The City”, which was supposed to be level 1 of the project. He’s sharing this on Darkstone for everyone to enjoy and possibly learn from.

First of 3 Bonami retrocomputer fairs will be held on Sunday the 24st of March. The location is Heemradenlaan 130 – 7329BZ – Apeldoorn and it opens for visitors at 10am. Darkstone will be there!

This great game made by Lord Zett and Edwin (infinity) is now opensource
A nice way to look into a game how it’s made.

Download the Pixiedust sourcecode from Infinite’s website; it comes with music and GFX.

If you have questions about the code go to Infinite’s post about open sourcing Pixiedust.

You now can play Pixiedust!
Download Pixiedust from #msxdev 2012 website or watch:

Darkstone has finished designing a component that will be used (among other components) for a much larger project Darkstone’s working on. This finished component is however already available for those interested. It’s an electric power converter that converts 9 volts to 200 volts, to light up nixietubes.

Nixietubes are vacuum tubes containing numbers or other characters which can be controlled by the user. Great components for DIY fans creating new and unique electronic devices! The voltage can be controlled with a potentiometer on the circuit board. It supports a maximum of 10 watts, which is enough for several nixietubes.

For 65 euros Darkstone can create one such circuit board for you, although this price can drop significantly when larger quantities are ordered.


Darkstone enters the #msxdev compo with Pixiedust. It is an autoscrolling maze game written for MSX2 128K VRAM.

2012’s Bonami retrocomputer fair will be held on Sunday the 30st of September. The location is Heemradenlaan 130 – 7329BZ – Apeldoorn and it opens for visitors at 10am. Darkstone will be there!


From this day forward Darkstone will have a new logo.
The old logo won’t go away; it will be kept for specific products where the old style fits best.

Darkstone designed the new logo of the #msxdev compo. a fresh green/yellow logo! Check it out @ MSX-Banzai!.

Some time its just nice to do some tile art on a tms9928


Lord S.M.Zett has created a new MSX case mod. This time he used a well known style called ‘steampunk’. Although the motherboard comes from  an NMS8245, this new MSX is much smaller, and has a case mainly made from wood.

2011’s MSX fair will be held on Saturday the 22nd of January. The location is the big room (B3) of Wijkcentrum (community centre) Hatert in Nijmegen and it opens for visitors at 10am. Darkstone will be there!

Idar is a region on the island of Daq, somewhere in Earth’s history. When
a lord (or land lord) of Idar knows he’s soon about to pass away, a new
lord will have to be chosen. This is done by means of an old game, to be
played by the lord’s house.
In the shape of a traditional board game, four aspiring land lords strive

for the honorable title of lord. It’s a fierce battle where the dice will point out the winner.

For msxdev10 we created  this game! Download it now here ROM and Manual. Read more on the site of msxdev here.
