Description

UltraFast adult games compressor v3.1.3.30 final (UAGC) reduces game sizes by automatically compressing images, audio, and video. It supports a broad range of engines and platforms, including Ren’Py, RPG Maker MV/MZ and VX Ace, TyranoBuilder v1, HTML, Wolf RPG, QSP, GameMaker, Java, Adobe Flash, Electron-based games such as those made with TyranoBuilder v2, Unity, Pixel Game Maker MV, Godot, and kirikiri. Its main advantage is simultaneous media processing: multiple images and audio files—and, in some cases, videos—can be compressed together for substantially faster results on capable hardware. Image and audio speed limiters help manage the workload on slower PCs. The v3.1.3 v30 final development build is available in full and slim packages, with or without the Ren’Py SDK. Supported formats vary by engine. For kirikiri games, UAGC can process BMP, PNG, MPEG-1 MPG, VC-1 WMV, OGG, and WAV files. RPG Maker MV/MZ support includes PNG and JPG images converted to WebP, OGG/MP3/WAV audio, and AVI, MP4, MPG, WebM, and MKV video converted to VP9 with Opus audio. Ren’Py compression covers all media formats supported by that engine. The tool requires 64-bit Windows 7–11, with Windows 10 or newer recommended because some functions may not work on Windows 7; a modern CPU and SSD are also recommended. The SVT-VP9 encoder requires AVX2 support. Without AVX2, UAGC can switch to libvpx-vp9 when UltraFast mode is disabled. Use a short, simple game path outside the user Downloads folder, and avoid non-Latin characters and apostrophes in directory names. Japanese filenames require an implemented and enabled non-Latin filename fix for the selected engine compressor; filenames containing “#” are unsupported, and “%” characters may also cause errors. To get started, extract the download to a location such as C:Tools or D:, launch uagc.exe, and select the appropriate engine button. The arrow on the right opens additional compressors, including HTML and Wolf RPG. Install Windows Media Encoder through the tool if you need to process kirikiri WMV files; on Windows 10, the installer may display an error at the end that can be dismissed with OK. APK compression requires Java SE 8, which can be installed from UAGC’s main page. To build compressed macOS versions of Ren’Py games, first run RenPy_SDK_7.0.0-8.3.4.exe. If extraction fails, manually extract it using 7-Zip or WinRAR into the folder containing uagc.exe. The SDK folders need approximately 12 GB of additional space, and manually adding other SDK versions is not supported. Compression replaces the original files in the selected folder, so work from a backup when you need to preserve them. The Ren’Py and RPG Maker MV/MZ APK compressors delete the original APK, while the Repack maker, including its Unity option, leaves a working repack installer rather than a directly playable game folder. Compatibility depends on each game’s assets and protection. In kirikiri titles, compressing menu images can introduce bugs, and some games cannot read backgrounds converted to JPEG; the “Compress images to png instead jpg” and “skip sysimage folder” options help address these issues, although varying folder structures make menu assets difficult to identify automatically. Cursed Armor II uses protection that can prevent it from running after decryption; RMDec or UAGC’s “encrypt decrypted files back” option may help. Lust Man Standing is unsupported because its image filenames contain “#,” while School of Lust uses custom encryption that requires separate decryption. Summer of Shame is supported from UAGC v2.9.6 onward, and support for the non-Unreal Engine version of Lust n Farm was added in v2.6.5.
