I had a look at this game, and I have something for you: a fixed version with working sound and music. Please, test it, this is provided also as WIP http://www.dreamcast.es/descargas/juegos/hydra.cdi.ziphttp://www.dreamcast.es/descargas/juegos/hydra-src.zip
- Fixed a bug when game tried to load from VMU and there was no file (now it checks propertly that /ram file exists).
- Fixed all SFX files, now they have a working WAV header so KOS can load and play them nicely. I used Audacity to fix all the WAV files.
- Fixed music using the new OPUS format, works much better than OGG in the latest KOS. To do that, first I converted original MIDI to AIFF, and then AIFF to OPUS thanks to the OpusEncoder utility.
Hope you enjoy it, and happy new year!
