PPEngine isn't just a 3D remake of the 1982 arcade game Pole Position, but a complete reverse-engineering of the original game's code. The result is something truly uncanny, following all the plays, beats and moves of the classic but rendering it with modern high-definition lowpoly graphics.
Creator Jonathan Thomas described his plan on Reddit:
I started back in 2013 reverse engineering the code from the original arcade ROM with the help of the MAME debugger and some primitive self-made tools to analyse instruction traces and create assembly source files that could be assembled back to the original arcade ROM.
Following this, I worked through the assembly source file to produce a portable C-based library containing the game logic for Pole Position. This library was used in two projects - the one you see here, and another project to convert Pole Position to the Atari ST - a 16-bit computer that was released in 1985.
Thomas also used the reverse-engineered code to create a near-perfect conversion to the Atari STE home computer. Gen X surely remembers how often home ports of arcade games were crudely remade from scratch, ending up as completely different games behind a facade of graphical similarity, so this'll be bittersweet viewing for some:
Last March, game devs Alex Schwartz and Ziba Scott gave a presentation at the Game Developers Conference called "1,500 Slot Machines Walk into a Bar: Adventures in Quantity Over Quality in which they described how their own dissatisfaction with falling revenues from mobile app stores led them to muse about bulk-creating crappy apps and seeing […]
We all know the game Operation in which the player must conduct surgery on a curious character named Cavity Sam. As the commercial goes, “It takes a very steady hand.” But as sci-tech historian Allison Marsh writes in IEEE Spectrum, Operation evolved from a very different electrified game called Death Valley that was invented in […]
Miguel Zavala, who has a Patreon, has created a huge number of 3d printable files for roleplaying miniatures and posted them for free download. It’s a delightful selection of oddball Dungeons and Dragons characters, including many inspired by the longrunning Acquisitions Incorporated series:
When the SNES launched back in the early 1990s, it changed gaming forever. One of the innovations was a gamepad with four action buttons — something that has remained a constant on controllers ever since. The 8BitDo SN30 Bluetooth Gamepad brings that iconic design up to date, with Bluetooth connectivity and support for multiple platforms. […]
