In short, MixSID not only provides a Double-SID solution for you, it also gives you control over details such as volume balance for each SID individually and of digi sounds, the addressing space for each SID and so on and so forth. You can change settings using the online configuration utility. Including clip cables so that the installation can be performed without soldering.

27.03.2022 - More footage of the WIP Amiga AGA port of 'Turrican 2'
This is the first release with World 2. As mentioned in previously, there is a form of parallax added to it that was not in the MS-DOS version. This does push the blitter, and these levels are more likely to experience slow downs. The slow-downs are not as obvious or severe as the original Amiga version due to being triple-buffered. More changes: Changes: - Contains the first three worlds (8 bosses) and the intro on two floppys. - Now comes in floppy and WHDLoad flavours with improved stability (I hope!). - Player can now die and will respawn (but has infinite lives). - CD32 pads are detected (controls below). - Player jump/fall rates fixed to match original. - Player shield/invulnerability on spawn working. - End of level music working. - Wind on World1-1 added. - Bounce weapon upgrades work. - Lots of other smaller fixes.
