Core package for Chimera.

Download the .chimeraCore file below for your machine's CPU and put
it in Chimera's Cores folder (File > Core Manager shows where
that is). A package runs only on the CPU it is built for. Chimera
downloads nothing itself.

You most likely want the x64 package. Take the arm64 one only if you know you are using an arm64 device.

Core	srb2legacy
Version	d2d7db76b73c56340e4a4c064cd6c18678b486fa
Built from	d2d7db76b73c56340e4a4c064cd6c18678b486fa
x64	srb2legacy-d2d7db76b73c56340e4a4c064cd6c18678b486fa-x64.chimeraCore
arm64	srb2legacy-d2d7db76b73c56340e4a4c064cd6c18678b486fa-arm64.chimeraCore

This is a nightly: it is never deleted. A movie recorded on this
package can be replayed against it for as long as this repository
exists.

tasinfo-srb2-legacy.lua is the TAS info overlay (speed, angle, position, momentum, spindash revs, timers, boss): open it in Chimera's Tools > Lua Console with an SRB2 Legacy project loaded (the README's "Game State and the TAS info script").

This is a development build: it is replaced on every change, so it
may stop being downloadable. For a build that is kept permanently -
which is what a movie needs to stay replayable - take a nightly.

Version index

The list of published versions of this core, for Chimera's Core Manager.

Written by tools/write-core-index.sh on every publish. This release is permanent
and carries no core package: it is a fixed address for one generated file, and
Chimera reads it instead of asking GitHub's API, which allows an unauthenticated
address only 60 requests an hour.

Do not delete it - the address is what every Chimera installation asks.
