CSave
Providing ability to save locally worlds in Minecraft Classic
About this Mod
CSave
csave is a small utility mod for minecraft classic that adds the ability to save files locally
in game you notice no change, but you are able to use the save menu. instead of this going to a minecraft.net server that is down for almost 15 years it will save your level in the minecraft_classic directory in your home folder.
the goal is to have every version of classic supported
yes, i know that there is a betacraft addon offlinedatsave, but csave is just better
and this is a jarmod, so you must add it to the jarfile

CSave server crashes on startup – what to do?
Most common cause: wrong modloader version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (c0.0.13a_03). You can switch loaders with one click in the panel.
Is CSave compatible with modloader?
CSave officially supports modloader for Minecraft c0.0.13a_03. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with CSave – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if CSave consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
