You will notice that Prang has gone to great lengths to make his latest spell" 1 " Virgin's involvment with soft-ware began maybe a year ago withthe marketing end. Unfortunatelythe programming end is just be- ginning to catch up, and compu- ter ware just can't be promoted up the charts like records can." 1 " Very funny, or should I say, 'That's Rich'. Nice of you to include your address. Remember folks, don't complain to us, write to Richard." 1 " To use the routine, you must call the code with RANDOMIZE USR(address) to switch on double height. This USR call must also be used to clear the screen, as CLS returns you to short mode." 1 " Thus endeth the reading of thethe runes, the signs, portents, forebodings of disaster. Press 'R' to read again, 'L' to LIST or any other to sally forth." 1 " This one, like 'Dr. Franky' isthe work of Martin Wheeler. The Virgin moguls had better hang onto him, he is practically their only asset, on the Spectrum at least."'" You are a sorcerer who is try-ing to save the world from the" 1 " This magazine is made up of a number of articles and programs chained together in a manner similar to the 'HORIZONS' tape that came with your computer. Itwill not work with microdrives." 1 " This is certainly the only shooting gallery I've ever seen where the ducks get out and eat your ammunition, but you have toexpect unusual ideas from a firmthat names itself after a blot- ting out of the Sun." 1 " This is Eclipse's first entry into the software maelstrom, andlike many such, it would have been a big hit if it had come out a year ago. Single screen arcade numbers are starting to pall, and this one, while quite intricate and actually having" 1 " There is continuous music too,which can be turned off from within the game by shooting the musical note in the little box over on the right. I don't thinkthat you score anything at all for doing this but it is extra- ordinarily therapeutic.": 1 " There is also a competition. Nothing to do with your game score, just some text questions.Send in the answers and maybe win a graphics input device. You can use Kempston, Fuller, or ZX Interface 2 joysticks, butwith only left, right, and fire" 1 " There is also a charming bug. When you get a high score, in- stead of typing your initials, press Caps and Symbol shifts to-gether, then press Enter three times and your high score will be identified by three dinky Pogoes instead of letters!": 1 " There are fifteen screens, allwith demons to dodge, objects tocollect, doors to unlock, and the like. I guess it's really a graphic adventure rather than a straight arcade game, but this distinction is becoming the hab-itat of nit-pickers, so I'm off." 1 " The routine will ignore TABs ATs and colour commands. It useswhatever colours are already on the screen, and it won't OVER orINVERSE either. You must pad outwith spaces to format columns," 1 " The routine does not work withLPRINT or LLIST, so you must useCOPY to get double height print. SCROLL works as normal, but ifyou use a command with more thanone line in the lower screen you" 1 " The other thing that disables the routine is the 'automatic' listing that you get when you enter or edit a BASIC line. Use LIST to get tall listings." 1 " The only bit missed from the coin-fed version is the incom- prehensible (Japanese?) cussing when your bouncing thing gets caught. The rest of the sound effects are good and the speed and graphics are a near match tothe original." 1 " The main attraction of this game must be the difficulty. I didn't get past the third screenand the later screens look quiteimpossible in the Demo mode. Youonly have three lives, too. It may be frustrating, but it won'tbore you after a few goes." 1 " The keyboard controls are the four corner keys, and that workspretty well."'" There are 16 levels, varying in difficulty, with double col- our changes and extra hazards onthe later screens." 1 " The easiest way to use it is to go through the articles in sequence, following the prompts.However, there is a table of contents on the next page, for those who wish to go straight toa particular article or program." 1 " The difference is that Willy may now find his way from room to room in many different ways, instead of the fixed sequence ofManic Miner. It doesn't say on the insert card, but there are some 60 screens. It also doesn'tsay that visiting the Attic ren-" 1 " The code is presently working in address ";tallcode;",but you can putit anywhere you like and it willrun without any modification. Itwill even work with Microdrives." 1 " The Spectrum runs at nearly four megacycles per second, but it needs four cycles to execute a simple m/c instruction, such as copying one register into an-other, so it takes a whole mega-cycle (at least) to do anything." 1 " The Pilots don't have time forthis, they are too busy enter- taining passengers on their oncein a lifetime visit to the Mach Two cockpit while the autopilot flies the plane." 1 " The COPY command does not turnoff the tall print like CLS doesbut do not put the 'taller' codein the printer buffer, as using the printer would wipe out the routine, leading to a crash." 1 " The 'fly' button gives you ex-actly the kind of wobbly, bumb- ling flotation that we are used to dodging when Prang is in the office. Combined with rather un-assertive gravity, it gets you about like a fairly senior sage." 1 " The 'Willy' saga continues, and if it is all very much in the same vein, then that's not at all a bad thing. This time itis claimed that Willy is engagedin a graphic adventure rather than an arcade game." 1 " The 'Prize' in question may beas much as `5000, provided that Arcade sell 25,000 copies, as they are putting 20p a copy intoa fund. Deadline January, so there's plenty of time. You haveto win the game and send in a photo of the final screen." 1 " Stunning graphic displays are what sells software nowadays, sothat is naturally what the top programmers, Phillip Mitchell included, are concentrating all their efforts on." 1 " Recently, adventure game nuts,having enjoyed an extended love affair with 'The Hobbit', have begun to complain that the use of graphics in adventures is no longer enhancing games, but is often irrelevant to the game or annoyingly slows play." 1 " Please note that some files load in an unusual fashion, but they all auto-run and tell you when to start and stop the tape." 1 " Perhaps when, burnt out (or even cured) at the age of 24, Matthew and Eugene go after a daytime job, Ford will hire themto write the urban cycle opti- miser for the 1990 model." 1 " Our pre-release copy of Zigzagdid not incorporate the new fastloading system that your copy isgoing to use. Too bad, we would have liked to check it out, as it is unlikely that faster load-ing will prove as reliable as the normal rate." 1 " Our Wizard Prang takes as muchinterest in multiple zeroes as anyone (though as a notorious cheat, he is not eligible to en-ter) and, pausing only to award himself unlimited lives, he shotright through the multi-screen" 1 " One helpful hint, (close your eyes if you don't want to know!)You can jump through the stair- cases if you hit the right spot. Oh all right, it may have beenobvious to you, but I wish some-one had told me.": 1 " Ocean actually paid the Arcademachine company, Century Elec- tronics, for the rights to make the home computer version of this game. Then Century folded. Ocean has been doing rather wellwith it though." 1 " Nothing else you can see (thuscleverly excluding other elec- tromagnetic phenomena and sub- atomic particles) ever travels anything like as fast. To see how far Concorde moves in the same period, at full chat of course, take a sharp pencil and" 1 " Mugsy's graphics are perhaps the best yet on the Spectrum. Two of the screens are actually little cartoon movies, and thereis an arcade-style shootout se- quence. Superb stuff." 1 " Kempston, AGF, and Quickshot joysticks are suitable, and you will want them unless you're an ace on the cursor keys. The mazewalls are not deadly and you caneven ram your foes, (some of them), but you won't need that camera right away!": 1 " In that speck of time, how farcan something really fast move? Take light, which travels three hundred thousand kilometres in awhole second. Divide by a mil- lion and you get three hundred metres, or three soccer pitches,more or less." 1 " In fact, the compiler is stillin there, and still usable, if you know the right numbers! Un- fortunately, we cannot reveal the details, as there is a com- petition at stake, and we don't want to spoil anyone's chances." 1 " I hope I'm still around to ferret out the POKE that will disable the top speed limiter and pass on the info to you. In the meantime, keep reading the LISTings!"'',"ED-" 1 " I am uneasy about the scenarioof the game, as it seems unfair to those who suffer such a de- formity for the rest of us to have fun over it, but I guess the same could be said about themovie that the game is based on." 1 " Given the sensors, manipulat- ing equipment, and software, a Spectrum could fly Concorde while totting up the takings of the duty free sales and BEEPing 'Come Fly With Me' in pseudo- random keys." 1 " Diagonal movement means that joysticks, mine anyhow, don't work too well, full of false neutrals. Kempston, Protek, and Interface 2 sticks work, but youaren't told this on the package,only in the program. Tut." 1 " But there is a link to the other megacycle, the one that bats about in the confines of Uncle Clive's range of little black boxes, and to a selection of other speedy items, like Con-corde and the space shuttle." 1 " But the game itself is neithernew nor terribly exciting. It's a gangsterized version of the old standard where you are run- ning a small kingdom and have todecide how much to feed the pea-sants, how big the army should be, and so on. The sort of thingthat regularily appears as BASIClistings in backs of magazines.": 1 " Both complaints could apply a bit to 'Mugsy', but without the graphics, little remains. Still, they are great graphicsand you will certainly find themdisplayed in your friendly localsoftware emporium." 1 " As you progress through the sectors, you need to catch in- creasing numbers of scarabaqs toget on, which seems to be the only increase in difficulty, andfor all the smooth graphics, it does get a bit samey eventually.": 1 " As chips get larger, the indi-vidual elements get smaller, andthe signal no longer has to zip back and forth for 300 metres todo one little thing, but only, say, 100 metres, and your compu-ter is three times as fast. As if it needed it. Really sophis- ticated autopilots, like the one" 1 " A faithful copy of that great little florin gobbler, Q*BERT, down the arcades. Some how beingchased about the screen by nastyitems always seems more true to life to me than blasting hordes of aliens, and this is one of the more humourous of the genre." 1 " 'Joystick compatible' the cas-sette insert says. Ocean don't like you to know which joysticksare supported until after you buy. It's Kempston, Protek, and ZX interface 2, so there. You only need left, right, and jump anyway, so the keys are enough.": 1 " and that's not much fun !!
