Most origin stories for id Software start with Commander Keen or Wolfenstein 3D. The real starting point is smaller and stranger: a disk-magazine platformer about a man in a baseball cap, and a joke demo built on top of it that got its creators fired from their jobs a few weeks later — on purpose.
A Softdisk Game, Not Yet an id Software One
Dangerous Dave was created by John Romero alone and published by Softdisk in 1990, a full year before Wolfenstein 3D and two years before id Software’s name meant anything to the wider industry — the collaborative moment usually associated with this game came later, with the tech demo built on top of it, not the original platformer itself. Softdisk ran a subscription “disk magazine” — a physical floppy disk mailed to subscribers on a regular schedule, packed with small games, utilities, and articles, refreshed every issue the way a print magazine would refresh its content. That format rewarded games that were quick to understand and quick to finish, and Dangerous Dave was built exactly to that brief: a man in a cap runs, jumps, and collects golden trophies across single-screen and side-scrolling levels while avoiding enemies and hazards. Nothing about the pitch was ambitious. What made it notable in hindsight was who was in the room making it.
Softdisk’s development studio at the time employed Romero alongside John Carmack and Tom Hall — the same three names, plus artist Adrian Carmack, who would found id Software a matter of months later. Softdisk functioned, completely by accident, as a proving ground where that specific group of people first worked together, well before any of them had a reason to think they were building toward anything bigger than the next disk issue’s deadline. The company’s whole model depended on a small, fast-moving team producing new, self-contained content on a strict monthly cadence, which is a very different pressure than shipping one polished release a year — and it’s a large part of why so much of what this team built at Softdisk looks, in hindsight, like practice for the much larger games that followed.
The Sequel Nobody Was Supposed to See
Dave’s own game shipped and did its job as disk-magazine content. What turned it into something more than a footnote happened a few months later, when John Carmack cracked a technical problem the rest of the PC industry considered essentially unsolved: smooth, pixel-perfect side-scrolling on DOS hardware, the kind consoles like the NES handled natively but PCs, with their tile-locked EGA graphics modes, supposedly couldn’t. To prove the trick actually worked, the team didn’t build something new from scratch — they took the first level of Super Mario Bros. 3 and rebuilt it, near-exactly, on PC hardware, swapping Mario’s sprite for Dangerous Dave. Tom Hall titled the resulting demo “Dangerous Dave in Copyright Infringement” as a joke about exactly how blatant the theft was.
It wasn’t meant as a finished product. The plan, briefly, was to polish the demo into a legitimate pitch and send it to Nintendo as an unsolicited proposal for an official PC port of Super Mario Bros. 3. Nintendo passed. But the scrolling engine underneath the joke was real, and it was good enough that Romero reportedly told the rest of the team, right around that point, that they needed to be running their own company rather than building tech demos on someone else’s disk-magazine schedule. id Software was effectively born from that moment, even though the formal incorporation followed months later, and the reworked scrolling technology went on to become the foundation of Commander Keen instead of a licensed Mario port — a game Apogee’s Scott Miller signed almost immediately once he saw it, in a partnership our Apogee shareware history piece covers from the publishing side. It’s worth being precise about what caused what here: the demo and the original 1990 platformer are related but distinct products, and it’s specifically the demo’s proof that smooth scrolling was possible on PC hardware — not Dangerous Dave itself — that’s usually credited as the spark behind incorporating id Software as a company months later.
What You’re Actually Playing
Strip away the historical context and Dangerous Dave itself is a compact, single-screen-to-side-scrolling platformer across ten levels of rising difficulty. Dave can run, jump, and — once a level hands him a gun — shoot. Each level hides a set number of golden trophies that must all be collected before its exit opens, so exploration isn’t optional the way it is in some platformers of the era; skipping a visible trophy just means a forced backtrack later. Patrolling enemies, spikes, water hazards, and bottomless pits round out the obstacle set, and the early levels are noticeably gentler than the back half, functioning as an unstated tutorial before the difficulty curve steepens.
A direct follow-up, Dangerous Dave in the Deserted Pirate’s Hideout, reused the same engine for a fresh set of levels — a pattern of fast engine reuse that both Softdisk and, later, Apogee leaned on constantly to keep shareware output steady without rebuilding tooling for every release. The two games are close enough in structure that it’s worth being specific about what actually changed between them and what didn’t, since “sequel” undersells how literal the reuse was.
| Dangerous Dave (1990) | Deserted Pirate’s Hideout | |
|---|---|---|
| Publisher | Softdisk | Softdisk |
| Engine | Original, built for this game | Same engine, reused |
| Setting | Mixed hazard levels, no theme | Pirate hideout theme throughout |
| Core loop | Collect trophies, avoid hazards, reach exit | Identical structure, new level layouts |
| Weapon | Gun, introduced partway through | Same gun mechanic carried over |
What that table doesn’t capture is the practical upshot: if you’ve played one, the other will feel immediately familiar rather than like a new game to learn. That’s not a criticism unique to Dave — it’s exactly how Softdisk kept its disk-magazine subscribers supplied with new content on a fixed schedule without every issue requiring a from-scratch production cycle. In practical terms, the original is ten levels, playable in well under an hour once the trophy locations are known — though a blind first run, with no in-level checkpoints to soften a death, reliably takes longer than that.
Playing Ten Levels With No Safety Net
- Treat the first two or three levels as a tutorial, even though the game never calls them that — use them to learn Dave’s jump arc and momentum before the design stops being forgiving.
- Grab the gun the moment a level offers it. Several later obstacles are far more manageable with ranged options than with jump-only platforming.
- Watch a patrolling enemy complete one full cycle before attempting any timing-sensitive jump near it — Dave’s jump commits fully once started, with no air control to correct a bad read.
- Don’t leave a level until you’ve confirmed every trophy is collected. The exit stays locked regardless of how much of the level you’ve otherwise cleared.
- Because levels are short, restarting a level from scratch after a death is almost always faster than trying to recover mid-level — there’s no checkpoint system, so treat each attempt as disposable rather than something to protect carefully.
What This 1990 EGA Game Needs From an Emulator
Dangerous Dave is light enough that DOSBox’s default settings handle it without adjustment — this is 1990 EGA-era hardware, well below anything worth tuning cycles for. If you haven’t set up DOSBox before, our DOSBox setup guide covers mounting drives and basic configuration from a blank install. Sound support in the original is limited to PC speaker beeps rather than AdLib or Sound Blaster output, which is period-accurate rather than a bug — Softdisk’s disk-magazine games generally targeted the lowest common denominator of subscriber hardware.
A Small Game Standing Next to a Much Bigger One
It would be easy to oversell Dangerous Dave by leaning entirely on what it led to, so it’s worth being direct about what it isn’t: it’s a small, simple platformer by design, without the scope of Wolfenstein 3D or even Commander Keen, and playing it expecting a hidden masterpiece is the wrong approach. What it is, instead, is a genuinely well-made hour of retro platforming and a documented, verifiable piece of industry history — the game that was on the desk when the specific combination of people who’d eventually make Doom first proved to themselves what PC hardware could actually do. Softdisk didn’t keep that group long; most of the future id Software team had left for Texas within about a year of games like this one. What’s left behind is a tight little platformer that plays fine entirely on its own merits, and an even better artifact of exactly where its creators started before anyone had a reason to remember their names.
