If PCSX2 shows "Memory Card Full" when trying to save Tekken 5 (or you can’t load/overwrite saves), follow this step-by-step guide to diagnose and fix it.
Before we dive into the solutions, it's essential to understand how PCSX2 handles memory cards. In the PS2, memory cards are used to save game progress, and each game uses a specific memory card slot. In PCSX2, memory cards are emulated using files on your computer's hard drive. By default, PCSX2 creates two memory card files, one for each slot, and assigns them a fixed size.
You can assign a unique memory card file to Tekken 5 so it doesn't share space with other games.
