It's November 30th, and young Tim has made a terrible mistake. Tricked into opening a window on his advent calendar a day early by Santa's evil brother, Krampus, he triggers an extra-dimensional portal and is pulled inside. He now finds himself trapped in a Christmas nightmare. His only hope of escape is to make his way through each day of the calendar, collecting the stars that will unlock the window that leads to the next one. If he can reach December 25th and unlock it, he will be free of the spell, and his Christmas will be saved. However, he is not alone - the Krampus minions are determined to freeze him out, and if they succeed, Tim will find himself Snowed Under, destined to become one of them forever. So grab that snowball Tim, you have 25 days to save!

Software Farm's

New cassette release!  An officially licensed and authorised reissue of the early 80s classic Hi-res graphic ZX81 game.  The cassette is priced at £7.00 - Grab your copy here!


NEWS:   20/10/2021    PRICE INCREASE :(
I'm really sorry, but I've had to put the price of certain titles up by £1.00 - I've found that raw material costs, and numerous other costs like having to buy new recording equipment and printing has made costs go up considerably. Please bear in mind that Cronosoft is still not-for-profit - I do still need to cover all expenses however, and there are a lot more hidden costs than just the price of a blank tape. I hope that we still offer great value for money. After all, a £5 game in 1983 is equivalent of around £14.60 in today's money. I want to keep Cronosoft going long into the future :)    Existing stock that is already made is still going to be sold at the old £6.00 price until stock runs out.

NEWS:   16/09/2021   
R.I.P.  Sir Clive Sinclair      1940-2021

It is with deep regret that I write that computing pioneering legend, Sir Clive Sinclair has passed away at the age of 81.  His inventions have left a lasting legacy on the UK computer and software industry, and on the many communities that have sprung up since.

THE IRON WOLVES   128K Spectrum

Now here... from the legendary Andy Remic - an epic 128K Spectrum adventure, The Iron Wolves, with graphics by the also legendary Clive Townsend.

EU BUYERS:  Due to new post-Brexit IOSS rules, there is a workaround to avoid large customs collection fees, and it's available via EBAY for EU only. This way, the tax is prepaid, so no nasty unexpected fees on delivery!   
UK and OUTSIDE EU:  Click here
EU you can Click here to buy
EU buyers are not blocked from buying on the website, but if you buy, it is not tax paid, so you may get a customs charge when it's delivered, so it's recommended that you use the EBAY link.




As of a result of Brexit, on 1st July 2021, a new law came into place so that requires ALL EU sales to now have VAT tax paid on all sales, even those of a value of 22 Euros or less, thus removing the previous tax free allowance.  It is not just VAT that would need to be claimed on sales at the destination EU country at 20%, but also any collection charge (usually around 10 Euros per order).  This means that a £6.00 cassette could end up costing around £20.00+ once it has been received by the EU buyer. 

Refusal to pay these collection charges and taxes would mean that we would have to pay for return, or have the items destroyed.  

I'm really sorry about this. I didn't vote for Brexit.  You can guarantee to avoid these charges by using our EBAY SHOP Chaosmongers2 for new releases, and pre-pay the VAT at checkout.

21/06/2021:           First Software Farm ZX81 reissue!  FORTY NINER


We're immensely proud to annouce the reissue of one the most famous games ever to appear on the Sinclair
ZX81 - Forty Niner, from Software Farm.  When this game was released, around 1983, it was as much a shock to ZX81 owners as Knight Lore was to Spectrum owners, and was the first commercial title to feature high resolution graphics, as well as quality arcade style gameplay, and was very warmly received by the gaming press and home computer fans alike.     Now, 40 years on, you can relive those times with a brand spanking new copy, authorised by the original creator and owner of Software Farm.  Forty Niner is just the start.... more Software Farm titles will be coming again in the future.

18/06/2021:         R.I.P.   Jason Kelk   (A.K.A.  TMR)

So sad to hear the news of the passing of Jason Kelk, games programmer TMR from Cosine, and Retro Gamer journalist, after a monumental 14+ month hospital struggle against COVID19.

Although I never actually got to meet him in person, he was invaluable at the start of Cronosoft, encouraging, supporting and supplying us with our first non-Sinclair games, with him being the creator of many of our games releases in the very early (and later days), such as Cyber Wing, Warflame, Reaxion, Lunar Blitz, ViColumn etc., across multiple formats, including the Commodore 64, Vic 20 and C16/Plus 4.
His games live on, and he made a massive mark on the world. Our thoughts are with his family. RIP.

AVAILABLE NOW:   New Release:   IDOL TIME for the unexpanded VIC 20

Now available, a great new platform puzzler from John Aycock for your unexpanded Vic on cassette.  Get your copy here....  

NINJA CARNAGE for 128K ZX Spectrum
Cronosoft is proud to announce NINJA CARNAGE - a huge new Spectrum game (filling a 128K Speccy twice over), coded for the Speccy by the legendary CLIVE TOWNSEND, and available in 7 different language versions.   Age 18+, contains adult themes and very strong language.

We have been featured regularly in RETRO GAMER magazine, with a 6 page special in issue 166, as well as oftenmentioned on the BBC, and in THE GUARDIAN and INDEPENDENT newspapers.  We also feature in Andy Remic's film MEMOIRS OF A SPECTRUM ADDICT, and it's sequel SPECTRUM ADDICT: LOAD "FILM 2"


Have you written a new game?  We would like to see it.   Maybe you wrote a great game back in the day, and would like to see it published again?    We'd love to do that for you if we can.  


NEW RELEASE  30/03/2021  -   PANDEMIC from Bob's Stuff 
Sinclair ZX81 16K


2021:  16/3/2021

Apologies, but I've had to tweak the cost of shipping for outside of Europe countries. The USA's USPS introduced a charge to other countries' postal services for handling parcels to the US, so the UK Royal Mail introduced a new 'ZONE 3', making the USA the most expensive place to ship an item to from the UK.  I'm sorry for having to increase the shipping costs for larger chunkier packages that I can't send as a 'large letter' rate (which is anything above 6 cassettes), but I've reduced the shipping costs where there are 6 cassettes or less. Unbelievably, to send 6 cassettes stacked side by side horizontally within a 2.5cm parcel is £8.00 cheaper to send as a letter than as a larger package where they're stacked vertically. Bizarre!

2021:  7/1/2021

Happy 40th Anniversary ZX81!  Lots of new ZX81 releases to look forward to in the coming year :)


Cronosoft is open for business as usual, but unfortunately, due to customs and other delays relating to Brexit, as well as delays caused by backlogs relating to COVID-19, mails is taking much longer than usual, particularly international mail.  For example, EU mail is taking around 3-4 weeks, rather than the 3-7 days it would originally have taken.   I'm sorry about this, but the situation is beyond our control, so please allow lots of extra time for orders to arrive.  We recommend that overseas European buyers limited orders to 1 or 2 cassettes at a time to reduce the risk of unforseen customs charges.   


Newly released games, and restocks of older titles have now had a price increase to £6.00 - Reluctantly, I've had to do this as the *very* few suppliers of blank tapes have had quite a substantial price increase over the past few years. When we started back in 2002, we could obtain inexpensive tapes from suppliers clearing out old stocks. However, whilst there is a resurgence in interest in cassettes, there number of suppliers seems to have dwindled, thus vastly increasing the price from the companies that still stock them.  I hope you agree that £6.00 is still a decent price, and probably what you might have paid back in 1983.
