Welcome!

Thank you!

I tested the most recent changes. The cursor lines up very well on the X axis. The Y axis is showing a ratio issue where the cursor alignment gets worse the further away from the axis center you get. The cursor ends up below the aim at the top of the game's visible area and above the aim at the bottom of the game's screen.

I don't have another game with this aspect ratio to compare to. Maybe I have something configured wrong with the Sinden gun's border. I am using RetroArch 1.10.0, which has the newer coordinate scaling. Other games in FBNeo have been good. It appears that this game allows the system mouse cursor to travel into the letterbox area on my TV above and below the game and is scaling the in-game cursor accordingly (so, for example, I have to aim into the blank letterbox area above the game in order to get the cursor to reach its highest position in the game).

Wow, I really didn't expect a fix for that particular issue. Thanks for fixing it. I don't anticipate running into desyncs in other games, but I will let you know if I find anything.

You're welcome!

The thing is, if it desyncs in Kaillera it will also desync with the input recording feature (Game -> Replay).  I know how frustrating it can be using either feature and it goes out of sync, so now a-days I put a high priority on fixing this kind of problem.

Alright!
I finally got game controller buttons (re)mapping working...



Next step is to prepare the push requests.

littlebear, thanks, it's a work-in-progress, should be back to normal in a few minutes!

It may be tricky to replicate. The idea was that one of my two friends would always be out of sync when starting up online, and it wasn't consistently the same player, so I don't think anyone had incorrect settings. Also, the other games I recently played online all worked correctly. Before posting this, I ran 3 copies of the game on the same PC on a Kaillera server, and I wasn't able to see any desync.

I had recently compiled a build which doesn't disable "restore full state on load" when using Kaillera, so I used a state at the start of the game to get past the sync problem. I find that the feature has around a 50% chance of loading the state in sync online for all players, but if it doesn't load correctly the first time, I can just start up the game again.

Hi Nick Reynolds,
After doing a bit of debugging I found the sources of the desync issue. 
If you find other games that have this issue with Kaillera, please let me know and I'll try my best to make a fix for them.
