多機種模擬器 ares 發布新版，更新如下 ：
New System: Arcade
We have added support for Sega SG-1000 based arcade hardware; hopefully the first of many arcade cores within ares (well, technically second because we had the Neo Geo, but that was focused on the console variant, the AES).
Due to the nature of arcade boards, Arcade cores use MAME format roms, and a game list rather than traditional rom files. You can set a path for arcade roms in "Settings -> Paths".
Arcade games will be grouped under one "Arcade" system, regardless of what system the Arcade hardware may be based on.
Please note that ares does not currently resolve parent-child relationships, so arcade rom zip files must contain every file required for that game; in MAME terminology, this is usually referred to as a "Non-Merged" set.
User Interface
A homebrew mode has been added to the settings panel; this is intended to enable features that are useful to homebrew devs but would harm performance for general gameplay. This setting is currently only used in the Nintendo 64 core; more information on this later.
- Auto save settings when closing the settings dialog.

- Correct the description of Weave Deinterlacing (horizontal -> vertical)
- Improve auto-detection of CD-ROM based games, drag/drop and command line loading are now more reliable
