Config

Config

NeroArcade's settings live in config/neroarcade.properties, created on first launch. Keys are flat (the dots are part of the name). Operators can reload the file with /neroland config reload; a key that says "restart" takes effect only after one. Numbers outside the range are brought back inside it.

Server keys are decided by the server and sent to every player when they join, so a client always runs the same budgets as the server. Client keys belong to each player's own computer: the server never sets or reads them.

Client (this computer only)

Key	Default	Range	What it does
telemetryEnabled	true		Anonymous NeroArcade-only crash reports. On by default; set false to opt out (restart). See Privacy.
client.scanlines	false		Draws arcade screens with CRT scanlines.
client.screenRenderRange	0	0–64	Draws arcade screens only within this many blocks. 0 uses the server's screenRenderRange; a larger number than the server's is capped to it.

Cabinets and seats (server)

Key	Default	Range	What it does
screenRenderRange	32	8–64	Blocks within which arcade screens are drawn, and within which a nearby player keeps a cabinet awake.
seatRange	3.0	1.5–8.0	How far a seated player may step from the cabinet before the seat is released.

Cabinets and the Duplicator do not use power in this version, so there is no power setting.

Runtime budgets (server)

Key	Default	Range	What it does
runtime.maxArenaSide	32	8–32	Largest arena side in cells; a cartridge with a bigger arena is refused.
runtime.maxEntities	256	32–256	Most moving things in one match; extra spawns do nothing.
runtime.maxInputPacketsPerSecond	30	10–60	Input packets accepted per seat per second; the rest are dropped (nobody is kicked).
runtime.snapshotMaxBytes	8192	6400–16384	Largest screen update; a bigger one is sent as a full frame.
runtime.snapshotHz	10	5–20	Screen updates per second to a cabinet's viewers.
runtime.keyframeTicks	40	20–200	Ticks between full-frame screen updates.
runtime.maxAwakeCabinets	32	4–128	Cabinets that may run a game at once; further ones queue ("ARCADE BUSY").
runtime.sleepAfterTicks	100	40–1200	Ticks a cabinet with nobody seated or near waits before it sleeps.
runtime.maxMatchSeconds	600	30–1800	Longest match; a match still running ends in a draw.

Switches (server)

Key	Default	What it does when false
multiplayer.enabled	true	Link Buses join nothing; every cabinet plays on its own.
leaderboards.enabled	true	Finished matches write no rows or personal bests; existing boards stay and are shown.
exchange.enabled	true	The Arcade Exchange refuses every action (listings stay); the app's export and import are off too.
link.enabled	true	NeroArcade does not register with the NeroLink companion app (restart).
link.actions.export_cartridge	true	The app cannot export a cartridge.
link.actions.import_cartridge	true	The app cannot import a cartridge into drafts.
pushNotifications.enabled	true	NeroArcade sends nothing to the NeroLink bridge, so no phone notifications; the app's events list still updates.

Exchange and economy (server)

Key	Default	Range	What it does
exchange.pageSize	8	4–16	Listings per Exchange page.
economy.coinOp	false		With NeroEconomy installed, taking a cabinet seat costs economy.coinOpPrice. A refused payment gives the seat back. If NeroEconomy is installed but its economy is switched off, every seat is refused.
economy.coinOpPrice	10	0–10000	Price of one seat.
economy.downloadPrice	0	0–10000	Price of one Exchange download, paid to the game's builder (0 = free).

Privacy and limits (server)

Key	Default	Range	What it does
privacy.leaderboardRetentionDays	90	1–365	Days a top-ten row is kept. Hard cap 365.
privacy.personalBestRetentionDays	365	1–365	Days a personal best is kept after it was set; beating it restarts the clock. Hard cap 365.
privacy.leaderboardMaxEntries	10	1–25	Rows on each board.
privacy.exchangeMaxListings	200	1–1000	Most listings on the Exchange; a full Exchange refuses, never deletes.
privacy.listingsPerAuthor	16	1–200	Most listings one player may have (operators exempt).
privacy.draftsPerPlayer	8	1–32	Imported drafts kept per player.
privacy.exportCooldownSeconds	60	10–3600	Seconds between two /neroarcade privacy export requests.
privacy.playHistory	false		Always false: NeroArcade keeps no record of which games a player played. Declared for the privacy notice.

Companion app (server)

Key	Default	Range	What it does
link.importPerHour	10	1–100	Imports one player may make from the app per hour (and at most 3 a minute).
link.push.recordCooldownMinutes	60	5–1440	Minutes between two "Record beaten" notifications for the same player and game.
link.digestHour	18	0–23	Server-local hour of the daily "Cartridge downloaded" notification.
link.libraryPageSize	50	10–50	Most games in one page of the app's library.
