Basic 10 Liner 2020

I love this competition.

I am constantly amazed at the originality and complexity of code that cleverer people than me can fit into 10 lines. Plus it explicitly bans machine language code so it is a competition very close to my heart ūüôā

If you want to enter this year you have roughly 1 month left before the deadline of March 21st 2020.

There is no longer any restriction on legal systems – any and all 8 bit computers are eligible.

Over the coming weeks I’m planning to post and review past winners and notable entries from the competition, including this bad boy from 2015.


I mean really, invaders in 10 lines? I can barely get ‘Hello World’ working in 10 lines.

Nintendo Play Station Super NES CD-ROM Prototype – Sony and Nintendo c. 1992

What can you do in 14 days? A fad diet? A holiday in the sun? Get half a month older? Well 14 days is what you have left to purchase the legendary Play Station Super NES prototype at its very first public auction. To quote Heritage Auctions, “this is arguably one of the most notorious, mysterious, and controversial artifacts of the video game industry” and it can be yours for….well, who knows? Current bid is $280,000 but it is surely going to go way past this.

Regardless of the rights or wrongs of the personal ownership of things like this, it is undoudbtedly of huge interest to video game enthusiasts and the retro computing community. Keep your eye on it over at Heritage Auctions now.


Game Of The Month – Chiller

chiller_tape Title : Chiller

Released: 1985, Mastertronic

Platform: Commodore 64

Format: Cassette







If for you, like me, money was tight when you were no but a child in the 80s, then you will fondly remember the Mastertronic ¬£1.99 range of games. Affordable software which, even if it didn’t always live up to the hype and the promises on the cover, did at least allow you to feed your insatiable appetite for new games. The thrill of chossing and buying a new game and the anticipation of loading it in, reading every word of the instructions on the way home.

Let’s be honest, we have all spent far more on¬†games which have dissapointed or were mis-sold or mis-advertised, some by the biggest magazines of the day and their paid for reviews, and Mastertronic had their fair share of duffers. But now and then you were pleasantly surprised with a cheap game that was actually playable, lasted more than a couple of hours and was a challenge and fun enough to easily warrant the couple of quid.

For me, Chiller was one such game.

Let’s get the music out of the way first. There are very few of the original releases still around. The ones with the actual rendition of Michael Jackson’s Thriller, writen by Julie Dunn (Gilligan’s Gold, Battle of Midway amongst many others), were withdrawn for, well, obvious reasons. A few made it out into the wild and there are still stories even today of them being found on ebay etc. But you will most likely, if you have a hard physical copy of the game, have one of the 2nd generation. Still great music, but not Thriller.

In fact Dunn’s contribution, along with coding and graphics by the Darling brothers, the founders of Codemasters (which is still going today) is the main reason this unassuming budget game plays so well. It’s early and may be based on the Game¬†Maker engine (some debate about that), but hey.

So….we’ve all been there. Your girlfriend has been captured and is being held captive in a haunted mansion and you are on your way to rescue her. There is no time for things like checking fuel levels of course, or grabbing a snickers bar for the journey – time is of the essence here, and on your way to liberate your love the car, of course, runs out of petrol.

No choice then but to continue on foot, and the most direct route is going to take you through a forest, obviously, a cinema, why not, a ghetto (bit awkward) and naturally a graveyard, ending up at the haunted house.

Forest Level

forest-level   forest

This is basically a straightforward platformer. Retrieve the blue magic crosses which are dotted around and avoid the spiders and skeletons. It’s pretty tricky and requires a few goes to get the timing and movement right. There are ghosts and zombies here and annoying bats, and if they touch you your energy will get drained (it goes down slowly anyway) . If only you had stopped for that snickers bar! No fear though, the mushrooms you will find can restore a bit of health, just make sure you avoid those poisonous toadstools!

Cinema Level

cinema-level   cinema

More ghosts and ghouls await in the cinema – again collect the crosses, avoid the baddies, preserve your energy. Rubble is falling down from the ceiling and the mysterious ice cream sales ladies float across the floor. Use the seats as platforms and grab those crosses! The easiest level in my opinion.

The Ghetto

ghetto-level   ghetto

Not sure you’d get away with having a ghetto level nowadays in a game – or at least not calling it that! Anyway, guess what. Oh, you knew already? Yes you have to collect the crosses, bouncing around the window sills and roof tops and avoiding the inexplicable flying night vultures.

The Graveyard 

graveyard-level    graveyard

More bouncing around gravestones, tress and a windy path/platform. Various night vultures (I think they are supposed to be bats bizarrely) and what look like cats, and of course ghostly ghosts and skeletons try to scupper your plans. Again, adventurers, grab those crosses!

The Haunted House

haunted-house    haunted-house-screen

OK, so more of the same. Avoid the odd tree climbing chappy, the skeletons etc. and leap around the roof and jump off the vines to gather all the crosses. Once you collect them all the love of your life appears at the doorway and you have a tea-top-table-turnaround (trademark jonnypencils) and go through the whole thing again backwards, like Satan himself. Only this time both of you will be collecting crosses, switching between the boy and the girl to collect blue and red crosses respectively. It’s a nice twist to prolong the game.

If I’ve made it sound easy, it isn’t. It’s a pretty challenging game and kept me entertained for weeks.

I wont post a video – there are loads out there – but if there are any of you left that haven’t already played this game, or new enthusiasts reading this for the first time, do find yourself an original or download a tap file and relive the glorious budget driven 80s !


A New Full Sized C64 in 2019? Here we go again…..

PC Mag reported back in Christmas that a new, full sized Commodore 64 is being released this year off the back of successes like the C64 Mini. Indeed the people responsible for the Mini, Retro Games Ltd,  are again involved in this new release.

I’m just leaving this here. Not judging. This old vs new debate has been raging long enough and will, no doubt, continue to rage. But what would you rather have? A real, original, 80s Commodore in all it’s retro glory or a brand new ’emulated’ version, albeit in a fairly realistic case? Why not just run your emulation on your PC? Or is this just some form of misplaced retro snobbery.

I’ll leave it to you to judge…




Game of the Month – Son of Blagger

Title: Son Of Blagger img_0192

Released: 1985, Alligata Software Ltd.

Platform: Commodore 64

Format: Cassette





Alligata Bites Back is, I think, simply a re-release series from Alligata Software, cut down versions (in terms of packaging) and cheaper. This one is released in 1985, 1 year after its first showing.

I recently got this as a present, along with lots more goodies, so we’re good for Game of The Month for another year at least!


The packaging is standard for the Bites Back series, green labels with stamped name, and minimal cover details.

Simple instructions on the inner sleeve include movement key mappings, and loading (press shift/run-stop).

Left = Z    Р  Right = X   Р  Jump=Return

The Restore key switches to Joystick Control.

Loading time was about 4 minutes and there is no loading screen or any other entertainment during that time. Just the flashing lines we all know so well.






Straight from loading you are presented with the welcome screen, and pressing space takes you directly to the first level.

The air starts to decrease Manic Miner style and you need to have your wits about you to find all the keys strewn around to end the level. Keys are off screen as well as on so you’ll need to move about ¬†and shift the scenery left and right, and think logically to get them all in the time allowed. Mechanics are a little frustrating but you soon get used to them – movement is again similar to Manic Miner, in fact the game is, of course, heavily influenced, as was Blagger before it.


One thing that hasn’t improved with age is my skill at the Blagger games! I find it really hard, and soon found myself wanting to load in a hacked version from my trusty¬†1541 Ultimate II, but resisted cheating to play through properly. Well honesty only gets you so far, and in my case that was the 2nd level! I will persevere though.

Playability is good. Good enough to be addictive, and the game is quick enough in terms of restarting to get you replaying once dead in a matter of seconds.

blaggerMusic is really good – I didn’t get annoyed with it at all, just the right level of benign, background tune to help move the game along. And the sound effects are few and far between but work.

All in all I enjoyed playing Son of Blagger and it will be one I’ll return to, added to the list of games I want to beat without cheating.


As I have previously mentioned, if a video/play through exists elsewhere I will link to it rather than reinvent the wheel, so please see AL82’s video below.¬†It WILL contain spoilers including the ending so if you don’t want to see that, don’t click!




Journey – 15 Minute Play Through (PS4)

I don’t mind weird. Or odd. I’m a fan of both, actually, but I don’t know…I like games to have a beginning and an end. Or at least a journey where you have a vague idea of where it is you’re going and where you might end up. Ironic, then, that Journey just leaves me¬†with a sense of bewilderment.

I have read other reviews gush out descriptive platitudes about how beautiful it looks, how moving it is and how some players inexplicably cry when playing the game, seemingly moved to tears by sand dunes and flying ribbons. Barely a mention of the ‘game’ or the mechanics.

There are puzzles to solve, how to create a bridge and gather ribbons to populate your scarf and fly etc. but no sense of what to do when you solve them. You may find yourself accompanying another player (CGI or real life) but the way they just sort of stand around and wait to see what you are going to do adds to the sense of confusion.

Admittedly I haven’t given it very long, about 20 minutes is all I could manage. Although by all accounts that leaves only¬†another 1 hour 40 mins gameplay, and I may revisit to see if it improves, but honestly, as a gamer for over 30 years I really don’t understand the fuss made about Journey.

I’m fully prepared to admit that it’s probably me, that I might be missing something, but games are very much¬†personal experiences, one man’s meat and all that.

Maybe I’m dead inside, but I’d take¬†zombie blasting, shot gun slinging shooters any day of the week over this!


Programs on Vinyl

About 12 years ago I ran a successful Vinyl to CD/iTunes service and was really busy – from entire Jazz collections (literally, hundreds of LPs) to one off privately recorded 78s, I digitised them all. Then with the advent of cheap plug-and-play USB turntables the demand petered out. I still do it for myself and friends and the occasional commission, but no longer can it be called a business.

Anyway, the upshot of all that is I have boxes of vinyl lying around that I have acquired, and one of those boxes was a closing down sale, old stock from a record shop, full of around 1000 7″ singles. It was in this box I came across a single by Mainframe – Talk To Me.

What really grabbed my attention was the B Side. Talk To Me contained 4 programs for the Apple II, ZX Spectrum, BBC B and ZX81 – Vinyl and Retro Computing? All in one place? To the audio cleaning lab!

So of course, I had to get the vinyl recorded and hopefully somebody can load it in to one of these great computers to see what Mainframe were trying to tell us back in 1983. I don’t have any of these anymore (see previous post) and sadly the Commodore was not catered for. Audio at the end of this post.

I did find a great article over at so do click through to read more about programs on vinyl.



BBC Model B

Apple II


The big news this month is I have sold, yes, sold some vintage computers to make some room and get a bit of much needed cash. Obviously not the Commodore 64 stuff, that would be silly, but the Amiga and Spectrum have now gone.

3D Illustration of a Gavel Placed Above the Word Sold

Actually, apart from money and room, the other major reason is time. I just don’t have the time to dedicate to lots of different hardware, and I really do need to dedicate myself to learning Assembly on the C64. So decision made, the Commodore setup in the Retro Corner is now fully geared towards development, and I have sourced some definitive books on the subject, thanks to the great Commodore 64/128 facebook group.

This blog is where I will be keeping a track of my game dev – first things first, storyline/title stuff like that. Not even sure what genre. All great fun though and I’m excited to see what I end up with.

Oh and I’ll keep the Amiga/Spectrum tabs as I am absolutely certain that I’ll be collecting these machines again once space/time/money allows! This is the curse of the collector. The cycle of selling and collecting continues….
