freefrank/ModernRetroRomManager v1.3.0 on GitHub

Export can now write both gamelist.xml and metadata.pegasus.txt in a single pass, and this "both" option is the new default, so an exported library works with EmulationStation/batocera and Pegasus front-ends at the same time.
The batch action bar gains hide/unhide buttons for the current selection.

Exported media is now copied strictly by metadata reference — only the assets the gamelist/pegasus actually tracks — independent of file extension. This ends both silently dropped media and unreferenced orphan files.
Multi-track disc games are de-duplicated on load: a single .cue referencing several .bin tracks (Track 1/2/…) keeps only the cue; .mds/.mdf and .ccd/.img/.sub sets behave the same.
Disc descriptor files (cue/ccd/mds) now report the whole game's size (folder or sum of tracks) instead of the few-KB descriptor.
Hidden ROMs are no longer copied to the export target (previously they were only omitted from the gamelist); BIOS files are still copied.
One-way sync now cleans the target before copying from the source.
The export dialog remembers the last-used export directory.
Console copy/scan/scrape progress updates in place on a single line instead of flooding new lines; console log text can now be selected and copied.

Scraped media from providers that serve images through .php endpoints (e.g. ScreenScraper) were saved with a .php extension; the extension is now taken from the response Content-Type.

导出可一次性同时写出 gamelist.xml 与 metadata.pegasus.txt，并将“两者都导出”设为默认，导出的库同时兼容 EmulationStation/batocera 与 Pegasus 前端。
批量操作栏新增隐藏/取消隐藏按钮。

导出媒体改为严格按元数据引用复制（只导出 gamelist/pegasus 实际追踪的资源），与文件扩展名无关——不再静默漏拷媒体，也不再产生无人引用的孤儿文件。
多轨光盘游戏加载时按文件夹去重：单个 .cue 引用多条 .bin 轨道（Track 1/2/…）只保留 cue；.mds/.mdf、.ccd/.img/.sub 同理。
光盘描述文件（cue/ccd/mds）显示整个游戏的总大小（文件夹或多轨之和），而非仅描述文件本身的几 KB。
隐藏的 ROM 不再复制到导出目标（此前仅从 gamelist 过滤）；BIOS 照常复制。
单向同步改为先清理目标、再从源复制。
导出界面记住上次使用的导出目录。
控制台复制/扫描/抓取进度就地行内更新，不再逐帧刷屏；控制台日志可选中复制。

部分通过 .php 端点返回图片的抓取源（如 ScreenScraper），媒体被存成 .php 后缀；现改为按响应 Content-Type 确定扩展名。
