Apple //ix
==========
Apple2ix is an Apple //e emulator implemented primarily in C with x86, x86-64, and ARM assembly language for the 65c02 CPU emulation module. In addition you will find a smattering of interface code in Objective-C/Cocoa, Java/Android, and GLSL.
Apple2ix is an Apple //e (8bit 65c02 CPU) emulator designed to work on varios POSIX platforms.
Project Tech
------------
* C99 dialect of the C programming language for the majority of the project
* x86 and ARM assembly language for 65c02 CPU emulation loop
* Extensive tests for 65c02 CPU, Apple //e VM, disks, and display (expected framebuffer output)
* OpenGLES 2.x graphics with simple portable GLSL shaders
* OpenAL and OpenSLES audio (emulated speaker and emulated Mockingboard/Phasor soundcards)
* Objective-C and Cocoa APIs (Mac/iOS variant)
* Java and Android APIs (Android app)

@ -17,7 +28,7 @@ Project Goals
* Portability and code resilience across a wide range of modern platforms including MacOSX, desktop Linux/BSD, iOS, Android -- *But not Windows, just use the excellent [AppleWin](https://github.com/AppleWin/AppleWin) emulator if you're on Windows!*
* Reasonable emulation fidelity to the original Apple //e machine (timing, video, audio, etc...)
* Language minimalism for core emulation modules (prefer coding in POSIX C over all else), except for CPU module which should be in assembly
* Language/platform/API minimalism for core emulation modules (prefer coding to POSIX APIs and using C99 over all other choices), except for CPU module which should be in custom assembly or IR ;-)
* Good platform citizenship for menu system (prefer coding in language-of-choice promoted by platform--e.g.: Objective-C/Swift on Darwin, Java on Android, ...)

Due to Apple's policy about emulators we are unlikely to ship this in the App Store any time soon.
iOS port in progress 2016, check this repo and fork(s) too!

Semi-Ordered TODO
-----------------
* DHIRES graphics are ugly, fix 'em
* iOS/iWatch ports
* Double-LORES graphics (used in Dagen Brock's Flappy Bird clone) are ugly/incorrect ... fix 'em
* Mockingboard is seriously buggy. Need to research/check upstream for bugfixes and refactor.
* CPU module ports: aarch64, x86 without textreloc's, Clang IR
* iOS/iWatch ports. iOS in progress early 2016.
* Proper VBL timing and vSync matching to the device (if available)
* OpenGL shaders/tricks for style (various screen artifacts) and functionality (Disk ][ status overlays, etc)
* Emulator save/restore and image compatibility with AppleWin
* Other feature parity with AppleWin
* Improved debugger routines (CLI/curses debugger?)
* CPU module variants as-needed in aarch64, plain C, Clang IR, ...
* Emulator save/restore image compatibility with AppleWin
* Emulation features ... (3.5" disk, AppleHD, Phasor, printer, ethernet, ...)
* Debugger rewrite with tests ... improved debugger routines (CLI/curses debugger? GDB/LLDB module?)
* Emscripten/web frontend?
