From 6a0c0a483503c1a3bbdc5d0b74464d2dba2eb70f Mon Sep 17 00:00:00 2001 From: Zephyron Date: Sun, 11 May 2025 20:22:13 +1000 Subject: [PATCH] service/ssl: Add ssl:s service and fix SSL-related crashes in Xenoblade X Implements the ssl:s service alongside various SSL-related functionality that was causing Xenoblade Chronicles X: Definitive Edition to crash. The changes include: - Add the ssl:s service with proper command handlers - Add InfoType::TLSCapability (0x1C) to the system call handler - Implement a stub SSL backend for basic network operations - Add FlushSessionCache functionality to both ssl and ssl:s services These changes resolve the "TLS initialization failed" crash and the "Unknown function '5': port='ssl:s'" error that were preventing the game from starting. The implementation is mostly stubbed, allowing network requests to pass through unencrypted but enabling games to proceed without crashing.
