RxNES v1.53 is released. RxNES is basically 80 lines of code added to an Open Source NES Emulator within the Unity3D Engine. Unity3D is not required, you can upgrade games with the Standalone Build.

RxNES v1.53 Changelog:
- Fixed # Key not running Box Art Downloader. Changed it to the 3 Key for now.
- Uncommented code for 3D Models in Recording Playback. The bug was elsewhere. (I think.)

- Rom Browser with Box Art! Toggles with "Page Up" & "Page Down". Arrow Keys to select your Rom.
- Box Art Batch Downloader. Hold "Shift" and press #. (Can take 10 Seconds to 20 Minutes depending on how many Roms / what art is missing.)
Currently the Server has Art for 600+ Games! (Games are mostly Auto-detected, regardless of file name.)
- No 3D models in Replay Recordings (Needs further testing and tweaking...)
