Brilliant! Thanks!

Cool idea! Sorry, this is just me randomly brain storming ideas for a potential implementation...

Maybe the module could load config files for soundbank and fanfare, in the format:  "Team name","TUS URL to file download", EG:

Team One,https://www.tus-wa.com/files/file-2594/
Team Two,https://www.tus-wa.com/files/file-2592/

Considerations:

- Only support TUS URLs - for security and reliability
- Only extract/load game WAV files from the archive, to ensure no other rogue files or file types can make it onto someone's machine.
- For TUS, it looks like .7z, .zip and .rar archive formats would need to be supported
- If a wav file is missing, replace that file with default sound wav
- Maybe cache files locally based on the identifiers in the URL rather than hashing, I guess it depends if people update the same sound banks often.
- File size  limits? 
- Dynamic download and loading.  Rather than wait for all players to download the files, the game can proceed and WAV's are re-pointed in memory as downloaded WAV's become available. Until then, the team's chosen game sound bank is used
- Replay support?  Record the ID's for each team's soundbank and fanfare (perhaps in an accompanying config file rather than modding the replay format).  A config option to disable using/downloading soundbanks for replays.

Cool! SIBASA actually plans to update it one day. It has some details that could be changed, yes. But, most of the hardwork is done and the terrain was released on the mangrove day as planned! And... It really makes you feel that you are indeed in a mangrove forest.

I wouldn't change any of the objects or colour scheme, it has a really nice vibe.  I would try to create a bit more separation from the background so that tiny bits of terrain can easily be seen during play.  There is a fair bit of grainy dithering and dark pixel aliasing which could be sorted.   Each object could be reduced a lot before indexing everything down, like this example with the brown pelican, to get a cleaner look and help free up more palette space for other areas like the background.  Give me a shout if you need a hand, I think it would be great to see this one updated/refined.

Really nice theme! ... and educational   If you guys are up for doing a version 2 I have some suggestions to improve playability and palette usage, which should make it easier to add more objects as well.

I've updated this terrain with a new dual-layer background (supported in wkTerrainSync)

The original texture uses nearly half of the palette which most of the 32 terrain objects share, so there won't be much room for new colours.   I've attached the full 113 colour palette file for the terrain (112 + transparency).   If you force your new texture to remap to that palette, all objects and background etc will work perfectly.

I just tried a batch levels adjustment across all images rather than redoing the palette which would take a while.  This means the background is made darker by the same amount (not ideal).  Example comparison below made from screenshots in the game.  Possibly a bit too dark (?) but if this is useful I can upload it... Or I may just re-pallete it when I get time
