A true 2.5D Retro Renderer using old-school Raycasting gives RFS the ability to replicate visual quirks of retro games. Using techniques from the DOS era, it reproduces almost-zero near clip, classic depth sort, no z-fighting, and more.
The game editor of RFS assumes no programming knowledge. Thanks to its powerful polygonal room support, complex levels for your games are easier to make than ever. And yet, RFS is a small portable program, with everything you need.
Exported games and RFS's editor support most 64-bit systems, even no 3D accel via its Raycaster's Software Rendering. Many low-powered ARM64 Linux computers like newer Raspberry PIs work too, thanks to cross-platform support.
Despite raycaster looks and first-class retro MIDI integration, RFS is a modern 64-bit app with high-DPI, widescreen, gamepad, touch, and mouse aim support. Its RFS2 Engine was written in fast C code to run well on older and newer devices.
