Following on from both Old School Demos 1 & 2 comes 'Old School Demo III', released by Cosine.

The demo can be downloaded from the Cosine website...

The demo is 'interactive'.  At the start, all sprites are switched off and certain keypresses will switch sprites on. Also, there is a hidden part activated with a certain other keypress...

All code, graphics and music is by me.  The moon image came from a little organisation called NASA ;)

Included in the download archive is the PureBasic source and all the graphic and music files in their original formats.  What's new for me coding wise?  A vertical scroller, extensive use of transparencies, keyboard control, scanline emulation and further refinement of my design and coding techniques.  More info is in the scroller.

Tools used for this demo: PureBasic 5.60, Photoshop 7.0, MS Paint, Promotion 4.5, Crimson Editor, OpenMPT 1.27, Amiga ST-XX sample disk images.

Purebasic / Beast Tribute
« on: May 22, 2018 »
I may be a few weeks later than others, but wanted to contribute to the other Psygnosis style demos that have appeared on this forum courtesy of KrazyK and ~AR-S~.  So finally, here is my effort, that I've called 'Beast Tribute'.

The demo can be downloaded from the Cosine website here:

Like my previous demo (Old School Demo 1), the source is included and is very heavily commented to explain what each bit is doing.  Unlike the last demo, I've not converted the graphics into data and included in the source.  This time the graphics are in their original formats so you can see how it all slots together.  Also, I wrote some new music - although it loads into the demo as an ogg file, the original 4 channel mod file is included so you can load that into whatever tracker and pull that apart too!

Thanks to KrazyK from this forum for pointers on animation control.  All other thanks, credits and information is contained in the demo scrolling message.

Please enjoy!


Purebasic / Old School Style Demo
« on: April 08, 2018 »
Cosine, the group I'm part of, has just released a very simple old-school style demo that was coded using PureBasic.

It was coded to learn a few things about screen, sprite and sound handling in PureBasic.  Although I have coded a few applications in PureBasic, this was a bit of a departure and was done to get a few routines under my belt to be used in a couple of upcoming games, basically PC based conversions of some of our 8-bit games.

A thanks must go to various people on various forums who are always kind enough to share their source and which gave me inspiration on how to achieve various effects.

The demo looks a little like this...

The release zip file also includes the source which has been commented to the max in the hope that others just starting their PureBasic adventure may learn something.  Having said that, I'm no professional coder and my 'style' of code may poke more seasoned users in the eye... ;)

The demo called (rather unimaginatively) 'Old School Demo 1', can be downloaded from this page on the Cosine website:

Purebasic / UltrafontPC
« on: February 24, 2017 »
UltrafontPC V0.9b by Arkanix Labs

UltrafontPC is an application coded in PureBasic to assist in designing hires character sets for the Commodore 64. This Windows application is inspired by the C64 native Ultrafont program by Charles Brannon.

UltrafontPC serves as a companion piece to our CartographPC, an editor used to create maps from hires character sets.
