Wanting to learn more about how the old DOS games I used to play I wrote a 8086 emulator with just enough simulated os functionality to run simple programs and games.
Alley Cat,for example, is almost playable. There are however some bugs that need to be fixed and functions to be added.

This program is meant to aid in analyzing old 8086 software while executing it. It’s not intended to be user-friendly or to offer broad hardware support.
Feedback and bug reports are welcome, however I’m unlikely to implement entirely new features before I have managed to run most simple games (8086 textmode/CGA/pc-speaker) in a manner where are they are actually stable and playable.
