 # Agent Task Audit Log - Ample Linux Port
 
 
+## 📅 Session: 2026-05-19 (Session 5)
+
+### 🎯 Objective: Complete Slot Configuration Persistence (MAME Command Line)
+Synchronized command line argument logic with AmpleWin to ensure "None" slots are explicitly disabled in MAME.
+
+### ✅ Key Achievements:
+1.  **Command-Line Slot Persistence**:
+    *   Modified `build_args` in `mame_launcher.py` to allow empty string values (e.g. `option is not None` instead of `if option:`).
+    *   This ensures that `-[slot_name] ""` is explicitly passed on the command line, preventing MAME from falling back to its internal defaults.
+2.  **Cross-Platform Parity**: Ensured consistent behavior with Windows and Web ports.
+

+
+## 📅 Session: 2026-05-11 (Session 4)
+
+### 🎯 Objective: Slot Configuration Consistency Fix
+Synchronized slot initialization logic with AmpleWin to fix "None" persistence issue.
+
+### ✅ Key Achievements:
+1.  **"None-Aware" Slot Initialization**:
+    *   Applied the `slot_name not in self.current_slots` fix to `main.py`.
+2.  **Cross-Platform Consistency**: Ensured Linux port shares the improved slot behavior.

 # Agent Task Audit Log - Ample Windows Port
 
 
+## 📅 Session: 2026-05-19 (Session 15)
+
+### 🎯 Objective: Complete Slot Configuration Persistence (MAME Command Line)
+Resolved the issue where selecting "None" for a slot in the UI didn't actually disable the device in MAME because empty slot arguments were being omitted from the command line.
+
+### ✅ Key Achievements:
+1.  **Command-Line Slot Persistence**:
+    *   Modified `build_args` in `mame_launcher.py` to allow empty string values (e.g. `option is not None` instead of `if option:`).
+    *   This ensures that `-[slot_name] ""` is explicitly passed on the command line, preventing MAME from falling back to its internal defaults.
+2.  **Parity**: Checked and verified this behavior across both `AmpleWin` and `AmpleLinux` ports, ensuring slots explicitly set to "None" are truly disabled when the emulator launches.

+
+### 🎯 Objective: Slot Configuration Consistency Fix
+Resolved an issue where slots with defaults could not be set to "None" because UI refreshes would revert them.
+
+### ✅ Key Achievements:
+1.  **"None-Aware" Slot Initialization**:
+    *   Modified `initialize_default_slots` to use `slot_name not in self.current_slots`.
+    *   Ensured manual "None" selections are preserved while maintaining automated defaults for new card insertion.
+2.  **Upstream Compatibility**: Prepared codebase for PR back to original source, ensuring robust slot behavior.
