PLANES AND BOATS AND TRAINS...!

[ posted on 14th September 2009 ]

Yes, two Cosine releases in the space of a year - will wonders never cease?! This time we're presenting GR9 Strike Force, a horizontally scrolling shoot 'em up from T.M.R (there's a surprise...!) and Odie which was developed for the Retro Reunited event (12th to 13th September 2009) in Huddersfield, U.K.

The game was developed over a three and a half week period and features digitised images of a lucky Retro Reunited competition winner, who was given a silly hat to wear, photographed and inserted into the game live at the event!

COPYING BLOCKS SINCE 2008

[ posted on 21st March 2009 ]

Another year(!), another Cosine release... yes, it's been an absolute age and a half since the last product and there's just a hint of irony in the air as well because the latest release, Blok Copy DTV, is the same game as the last release! Well okay, it's not entirely the same because although it plays pretty much identically to the original PET version, this port looks graphically slick because it runs using the 8 bits per pixel graphics mode of the C64DTV2 and has a superb SID soundtrack by our very own Odie rather than the beeper tune T.M.R cobbled together!

KIKSTART C16 CARTRIDGES

[ posted on 18th July 2008 ]

Recently, that nice James over at RGCD badgered persuaded T.M.R that cramming Kikstart C16 down to fit into an 8K cartridge would be a good idea. In fact, it would seem that it really was a good idea despite T.M.R's reluctance (not enough to stop him doing the code and spending a few days trying to remember how auto-starting cartridges work) and there has been a significant amount of interest to the point where Retro Gamer printed a news item about the cartridges in issue 53 (in the "retro radar" section on page 8, for those wanting to see how the boxes look) but there's a link to this website at the end of the piece and... umm, we don't actually sell the carts!

Kikstart C16 is freely available from this site as a download if you click the link at the start of this sentence in fact, but those who want to purchase it should ponder over to RGCD and nag them (or wait until it appears in the shop!)

SO WHERE DID THE REST 2007 GO...?

[ posted on 8th March 2008 ]

Woohoo! Here's the first Cosine release for 2008 and it's a case of "new year, new format" since it's our very first title for the Commodore PET, in particular for 8K machines with 40 column screens. Blok Copy is an action puzzler where the playfield gets scrambled and the player is then given control and a finite amount of time in which to straighten things out. The design and code were both by T.M.R and the game features graphics (well okay, screen layouts since the PET can't redefine it's characters) by Bizzmo and T.M.R along with a slightly screechy cover of "End Theme", some in-game sound effects and jingles that T.M.R had a go at producing which rely on a hardware hack to add sound to the otherwise mute PET.
