# Extracts the C64 and 1541 ROMs needed by vice_jni.c from vice-3.8.tar.gz.

# This is a manual/standalone equivalent of the `extractViceRoms` Gradle task
# in app/build.gradle.kts — same source paths, same renaming. Useful for
# inspecting the ROMs outside a full Gradle build (e.g. for the "bring your
# own ROM" flow described in docs/publish.md §0).
