RetroArch 1.7.8 is now available

After teasing some of their upcoming features, the Libretro team has just released their latest stable build of RetroArch: 1.7.8. This is a sizable update for the emulator frontend, offering many new changes and functions such as an "AI Service" which has a Speech Mode that can automatically parse text onscreen into speech, or an Image Mode that quickly pauses your game to overlay machine translated text from one language to another. Also new to this update is the RetroArch Disc Project, allowing for CD-ROM support so that players can experience their original game discs right through RetroArch's supported cores, or dump them into a bin/cue format.

Other, smaller additions, like touchscreen lightgun controls for mobile, on-demand thumbnail downloading, enhanced core options, and more, have been added as well.

A full changelog is available below:
