 Intro to small intros, part 1 and 2[posted by TMR on 08 December] 
We've got not one but two new little intros released today, the first is Femtotro, features code and graphics by T.M.R with music from 4-Mat and is an entry for the CSDb Intro Creation Competition. It was based on a compact Babygang intro written in 1991 that's included in Backlog.

Released alongside Femtotro was Zeptotro which has the same credits (although features far less graphics) and carries on where it's bigger brother leaves off when it comes to size coding, since it lives in the default screen RAM and doesn't use any memory above $7fff when running.

 Needs some introduction[posted by TMR on 24 November] 
The CSDb Intro Creation Competition is back for 2018 and, one day after Doctor Who day, so is Cosine with a new intro called Oldest Style. Fresh, 8580-powered music this time is by aNdy and the old school code and graphics are from T.M.R.
 Scary darey[posted by TMR on 31 October ] 
If your mansion house needs haunting just call... Cosine? Perhaps, but aNdy has just released his Halloween-themed Old School Demo 3 for those who like things that go bump in the night and have a DYCP scroller! Once again, the PureBasic source code and assets have been provided with the download.
 The daily grind[posted by TMR on 25 Septembe] 
T.M.R spends some of the time writing random things about demos at his blog and the most recent was Demo Factory, a release from the Dark Times before he joined Cosine! That post in turn lead to the development of Demo Factory 2018, a from scratch re-write with new graphics and music from Odie.
 In glorious FM[posted by TMR on 07 July 201] 
Developed in co-operation with Xentax, Odie FM is a collection of tunes which use Odie's recently written OPL2 music driver, supporting either a modified SFX Sound Expander or FM-YAM cartridge for some lovely FM audial goodness.
 It's absolutely beastly[posted by TMR on 22 May 2018] 
aNdy's back with another old school demo for Windows PCs; Beast Tribute - Old School Demo 2 was inspired by Shadow Of The Beast on the Amiga and, as with the previous release in the series, the PureBasic source code is provided with the download.
