How (and why) one man squeezed a modern console game onto MS-DOS

Last month's surprise announcement that pixelated open-world game Retro City Rampage will be ported to MS-DOS left us with a lot of questions. For one: Why? For another: How? Gamasutra talked to Retro City Rampage creator Brian Provinciano recently to get answers to those and other questions about the quixotic port.

In the interview, Provinciano says that a DOS version of the game was a "burning ambition that had been on my mind for at least half a decade, that I finally got to scratch." The porting took a month or two that Provinciano treated as a "vacation" after years of work porting the game to pretty much every modern platform.

Much of the optimization necessary to squeeze Retro City Rampage into a DOS-friendly format had already been done while doing a 3DS port, Provinciano told Gamasutra. Making that version required changing the HUD and cropping the screen to account for the lower resolution. It also meant "playing Tetris" with limited memory allocations, rather than just loading everything into RAM at once as in the other console versions.
