Grand Theft Auto - Vice City Stories

[Persephone]

Hello, I'm having major problems playing VCS. I've tried both the EU and US versions. Every time Vic tries to exit Fort Baxter for the first mission, the display adapter crashes and freezes the computer up entirely. I have to use Ctrl+Alt+Delete to open the Task Manager and force quit PPSSPP. LCS works just fine, so I'm not sure what's happening.

PPSSPP version: 0.9.8
Graphics card: AMD Radeon 6450.
OS: Windows 7 64-b
Processor: Intel i7-2600 CPU @ 3.4 GHz
