Castlevania dracula X ULKS46155

[Maronmario]

I'm experiencing a a few problems and a weird glitch with Symphony of the night on the Dracula X chronicles. Whenever I equip an item and then exit the selection for the item everything except the item equiped disappears. Is this a glitch with the Emulator or the rom? And Save rooms are extremely laggy, anyone know how to fix it?

And another thing: during the Dracula X chronicles main game the screen flickers or just turns solid black but the game still plays. Any way to fix it?
