A per-game relinker-patches.toml (or --patches) replaces verified bytes in
the input executable and bundled modules before conversion. Entries are
checked against the expected bytes and against every in-place writer,
the ELF header range and relocation targets. An <output-stem>.patches.toml
manifest records the applied entries, and --verify-patches checks an input
or a converted output. With no patch file the output is unchanged.
sceSslConnect verifies the server's chain under MBEDTLS_SSL_VERIFY_OPTIONAL and returns the first failure the connection's verify options select, with the SSL_ERROR_* codes KytyPS5 lists. The initial options are all five checks, so a connection whose title never sets them fails closed: with no CA loaded it returns SSL_ERROR_UNKNOWN_CA instead of throwing. The result is final for the connection: a failure sends close_notify, later sceSslConnect calls return the same code, and sceSslRead and sceSslWrite throw. A verify callback runs once after the handshake, outside the session lock, with the connection id, that code, handles to a copy of the peer chain that the context's certificate readers accept, the chain length and the user argument; a negative return fails the connect with SSL_ERROR_APPLICATION_VERIFICATION_CALLBACK_CHECK. The ALPN list set with sceSslSetAlpn is split on commas and offered, sceSslGetAlpnSelected returns the protocol the server chose, and the minimum version floors the handshake at TLS 1.2. A socket that would block returns SSL_ERROR_WANT_POLLIN or WANT_POLLOUT from connect, read and write and the next sceSslConnect resumes the handshake; the BIO maps a reset to MBEDTLS_ERR_NET_CONN_RESET, which returns SSL_ERROR_SOCKET_CLOSED, and tells a blocking socket's expired receive timeout, which returns SSL_ERROR_READ_TIMEOUT, apart from a non-blocking would-block. sceSslClose sends close_notify once and marks the connection closed. The debt entry records the default options and the situation-to-code choices as unverified and drops the title IDs.
Repacked copies and depth stencil copies allocated device-local memory
directly and stopped the title on a refusal; they now take the same
allocation path as the other images. Device buffers choose their host
fallback type the same way, the host placement line carries the cumulative
MiB, and the debt file records that a placed image stays in host memory
for its lifetime.
Converted guest modules never ran their DT_PREINIT_ARRAY entries: the
reader validated the array and the unused-NID filter kept its targets,
but no writer emitted or ran it. ld.so runs a shared object's preinit
array only for the main executable, so the Linux output runs the
entries from the DT_INIT stub before the module initializer; the macOS
and Windows outputs run them before the initializer in their startup
stubs, and the deferred Windows output exports a thunk that runs them
before the initializer for runtime-loaded modules. A module with a
preinit array and no initializer is still rejected, since the Linux
stub exists only with one.
