2017.07.01 N3S is a 3D NES emulator for Windows that is currently in alpha. It wraps the Nestopia UE libretro core and re-emulates the PPU to draw predefined 3D voxel meshes in place of 2D sprites. Current Features - Emulates PPU - Nametable scrolling and mirroring - OAM sprite data - Registers such as CTRL, MASK, etc - Detects CHR bank switching and draws sprites accordingly - Renders NES games in 3D - Replaces sprites with predefined 3D voxel meshes - Can draw partial sprites that are clipped by edge of screen or nametable scroll - Palette-based shader code uses actual palette data from PPU each frame - Mirrors sprites in shader code - Draws 8x16 mode if specified in CTRL register Planned Features - Support for games without CHR ROM - Meshes are generated when the game is loaded, so games with sprite data compressed in PRG ROM cannot be loaded. - Utilize built-in libretro features like save states, frameskipping, etc - Haven't implemented yet but comes with Nestopia libretro core - Built-in voxel editor - Allows users to sculpt truly 3D meshes for each sprite and export for each game - Sprites are 8x8x32 voxels - N3S file repository - "Official" 3D definitions will be curated in Git repository and downloaded by app automatically - Users can upload and revise N3S v0.3.0 Alpha Changelog: New Features: - Editor added. - You can currently switch between game and editor with ; (semicolon) and ' (single quote) keys, respectively. - You can read more about workflow and scene / voxel editor here: http://n3s.io/index.php?title=Editing_N3S_Files - Editor is not feature-complete, and N3S file format is subject to change in coming versions. I wouldn't recommend seriously tackling converting a game to - 3D yet as it may become incompatible. - Editor controls are currently hardcoded and listed below. Input system added - Can now bind multiple analog or digital inputs to various functions within the app. - Currently supports XInput and keyboard/mouse. - Bindings temporarily hard-coded, but will support remapping with config file or menu in coming versions. - GUI implemented, along with shader for overlay and text rendering. - In-app console output implemented, rarely used in current version Bug fixes: - Fixed audio issues when moving or resizing window. New issues: - Mesh info window in editor overlaps new buttons (VRAM, CHR pages) in scene selector GUI. - Buttons in palette window not always responsive. - Left analog stick moves camera and give NES directional input at the same time. - ALT key focuses Windows menu, even within editor. Outstanding issues: - Cannot play games with no CHR data / sprite data compressed in PRG. - Many games still have graphical glitches. - PAL games run, but at 60hz rather than 50hz. - Audio buffer still loops when accessing application menu bar. - Many menu items do not do anything yet. - Possibly unknown issues on different versions of Windows, has only been tested on Windows 10 x64. https://github.com/and0p/N3S -- ポーラステーション http://perry0517a.blogspot.tw/ --
