You could use things like ray tracing to determine if one player can be seen by another on the serverside and only send packages when they can see.
But to resource heavy to do that.
Edit: Thinking about it, you simply have to render the whole map with all players server side and based on that determine which players can see each other and based on that send the information to the clients.
Why would you use FPGAs instead of either trying to make the emulation better or fixing the code to work on new instructions.
And yea modding roms is more difficult but not as difficult as a. Trying to learn how the cpu on these old consoles function b. Learning how FPGAs work c. Programming these fpgas to worn like old consoles.
Only the dev team needs to know FPGA design. Not everyone. Just like the otherway. Someone needs to learn how to dump the ROM and probably needs to design hardware for it. Needs to dissasable it, edit the resulting mix of probably really special assembly (cause of special hardware) and then be able to compile it again.
Sounds much easier to do for every single ROM then designing the FPGA…
but since everyone has those skills that should not be a problem /s
Emulators are a nice middle ground. They are allowing to emulate the environment and you only have to create the emulator once and all/most ROMs are running. But still are not able to reflect the game to 100%. Talk about that to the speedrunning scene on older hardware. Some quirks/bugs/specific lags are not there.
FPGAs are the best way to preserve a console for the future. The hardware especially for older consoles was very special and custom, basically unique architecture.
While modding the ROMs seems to be easier, it has to be done for every single one and could lead to alteration of the game ifself (timing comes to mind) FPGAs have to only designed once per Console.
FPGAs get more and more accessible and cheaper every day. So for the future it will be way easier, cheaper and more accessible.
How should they even know? How should they prove that you are in posession of that data? Yes Hetzer most likely has to respond to reports but again how should the rights holder find out? Just because they find a jellyfin server in the wild? Even if the site is not SSL protected they are not Man in the Middle the traffic.
