Hello! I’ve kept working on Henkan, my osu!mania ↔ Etterna converter, and shipped quite a few updates since v1.5.0.The biggest new feature is a playable beatmap preview. The editor can now autoplay charts when you’re not interacting with it, notes render underneath the receptors like they do in osu!mania, and the HUD stays properly centered. It makes it much easier to get a feel for how a chart actually plays before exporting it instead of only looking at the note data.Henkan also supports 8 languages now. While adding localization, I ended up removing i18next and replacing it with a much smaller custom localization system. Henkan doesn’t really need everything i18next provides, so this keeps things simpler and lighter.I also improved importing incomplete osu! beatmaps. If you only have an .osu file and the audio or background is missing, Henkan can now automatically try to fetch the missing files from an osu! mirror.There were also a bunch of smaller conversion fixes. Skin images are handled more reliably, and previews should now be closer to what you actually see in-game. Release notes are fetched properly from GitHub instead of using the old placeholder, and config overrides now work consistently in both conversion directions.osu! exports got some fixes too. Backgrounds are included even when the source chart doesn’t directly reference them, cdtitle files are only copied when they’re actually needed, and hold notes were cleaned up to follow the normal osu!mania format with proper hitsounds and clean samples instead of creating unnecessary or broken sound files.I’ve also been trying to close the gap between the desktop and web versions. The web build now has much closer feature and export parity with the Rust/Tauri version, and CI automatically rebuilds the WebAssembly binaries whenever something is pushed to main.Keeping both versions in sync is still one of the more annoying parts of working on Henkan, since some converter changes have to be implemented separately for Rust and WebAssembly, but it’s getting a lot better.The goal is still the same: make Henkan the most reliable way to move charts and skins between osu!mania and Etterna without randomly losing important data.
