Re uploading SubaHibi since the originally torrent is stalled, with the partial english patch (~80% translated,most available unless you want to wait for the steam release)
To play:
1. unzip and mount the image
2. Run the setup file (it's in japanese, but if I remember correctly, you click the top option on the main screen, and then the left button to install)
3. Copy the patch files to the install directory (defaults to C:\KeroQ), and then run BGI-en (the english launcher)
4. Enjoy!
NOTE: You might need to change your locale to japan/japanese to run. I permanently keep mine like that, so not sure if that's required or not, but if you get an error message, try that to troubleshoot.
