It depends upon how they go to the brand new platform. There are two foremost methods of doing this – porting the sport challenge to the brand new platform or emulating the outdated recreation on the brand new platform.
Porting the sport principally means taking the outdated code and property and making them run on the brand new {hardware}. This includes getting the outdated recreation operating natively (i.e. the sport itself compiles, hyperlinks, and runs) on the Swap 2. That is often the selection for newer video games and tasks – stuff that’s newer often doesn’t depend on out of date instruments or a workflow that’s not supported. Since we are able to nonetheless use the instruments that the sport was constructed with, we (or some contracting studio) can get it engaged on the brand new {hardware}.
Emulating the sport means constructing a digital machine across the authentic recreation that pretends to be the unique {hardware} and modifies the inputs and outputs to and from the sport. Emulation is often finished when the sport growth workflow is not possible – e.g. the sport was constructed with historical instruments on historical {hardware} that’s not supported wherever. As a result of we are able to’t modify the unique recreation, we have to construct a field round it that we are able to modify and run the unique recreation inside that field.

The choice on whether or not to port or emulate is often pushed by what’s best and most cost-effective. Porting is often most popular to emulation if obtainable, as a result of it signifies that the porting crew has entry to instruments, property, and probably even the unique dev crew to reply questions. Emulation signifies that any gameplay adjustments are usually very troublesome since rebuilding the unique recreation might be unfeasible.
