Zombi was Ubisoft’s first game, a 1986 action-adventure built around George Romero’s Dawn of the Dead rather than any licence to it. Forty years on, a developer going by kikems has built a demake of it for the Atari Lynx, timed for the Silly Venture demoscene event and, apparently, for the anniversary itself.
A cartridge that thinks it’s a floppy drive
The Lynx gives a homebrew developer 64KB of working RAM and not much sympathy beyond that, and Zombi’s original graphics, double-buffered display and all, were never going to fit without a fight. The real problem wasn’t size, though. It was kikems’ assumption about Lynx cartridges. They don’t behave the way most cartridges of that era do: no continuous ROM access, more like an Apple II floppy drive, doling out data in controlled reads rather than letting the CPU pull from it freely. Everything that needs to be on screen has to already be sitting in that 64KB, which turns just streaming the graphics off the cartridge into a dead end.
Getting past that took a purpose-built sprite packer to squeeze the game’s art into the memory that was actually available, plus a custom compression routine to get enough of it onto the cartridge in the first place, given how slow those controlled reads are compared to true ROM access. Development reportedly stalled hard around this exact wall before the fix came together, which tracks: it’s the kind of constraint that looks like a footnote until it’s the whole project.
Old game, new hardware, same monster
None of this makes Zombi a natural fit for the Lynx’s small colour screen, and it was never going to sell a single extra unit of hardware Atari stopped making back in 1994. That’s not really the point. What it is, is proof that a console dead for three decades still has developers willing to fight its cartridge controller for the privilege of porting a forty-year-old horror game to it. The demo is out now, playable on real Lynx hardware or an emulator, for anyone curious what Romero’s zombies look like squeezed through 64KB.
