You can still use https://redream.io/ to play it. It's one of my favorite RPG. The emulator supposedly has superior graphics if you get the paid version for $6.

But you won’t get the physical screech of the machine as it begins to … (do something?) before throwing you into a random battle.

Anyone know what was happening under the hood? Why did the machine screech? I assume it was async loading a transition to the battle map, but why the screech?
