AEON v0.51 is released. Aeon is an application that allows you to run old 16-bit DOS applications in modern versions of Windows. It emulates much of the hardware of a PC with a 386 processor, including a VGA card, SoundBlaster card, General MIDI music device, and keyboard/mouse input. It also provides an implementation of most of the commonly-used DOS functions, mouse driver, and an expanded memory manager.

AEON Requirements
* Windows XP SP3/Vista/7
* 2GHz processor or equivalent (dual-core or better recommended)
* Direct3D-capable video card
* 16-bit real-mode DOS program to run
* Microsoft .NET Framework 3.5 SP1 (will be installed automatically if you don't already have it)

AEON v0.51 changelog
- 16/32-bit protected mode support added (no actual paging or protection works yet though)
- Fixed consistency issues with 16 vs. 32 bit stack and instruction pointers
- Fixed 32-bit addressing modes
- Small Sound Blaster DSP fixes, still lots of playback issues though
- Added support for a few FPU instructions
- Added extended memory support (XMS)
Most instructions now work with 16 or 32-bit operand sizes
- Fixed a few issues that caused hardware interrupts to get disabled when they shouldn’t
- Eliminated generation of multiple identical operand decoders (reduces memory usage, may increase performance somewhat)
- Fixed an issue with unchained 256-color (mode X) display modes sometimes getting rendered incorrectly
