> how does a game get ported? There are many options. A few points: - Some "ports" are done by running the original game in an emulator. - If you don't have source code or it can't be compiled for the target platform, you may have to rewrite from scratch (as was done in the case of SNES Doom apparently). - Depending on how different the programming environments are (e.g. operating system, threading primitives, graphics/sound APIs, memory - consoles often have exotic memory layouts), significant rewriting may be needed in order to get the game running on the target platform at all. - Once you have something that runs, it may perform like dog crap. In this case the porting job turns into an optimization and re-tuning exercise. This may involve not only optimising code, but also changing the quality of graphical/sound assets (artist work may be needed!), chopping off parts of the game (the SNES Doom does not have all levels, textures or animations for example, as the video says). - Many bugs may crop up with the rewrite, or bugs in the original game may be exposed by running it on a different platform. General debugging skills are very likely to be required. All but the simplest ports are likely to be an involved process, unless the two systems are very similar: for example, porting a game from Windows PC to Linux PC is likely to be relatively simple, compared to porting a game from PC to a primitive console.
