Hang if engine is installed more than once

[root670]

1. Launch CheatDevice
2. Boot to OpenPS2Loader with cheats enabled
3. Launch game in OpenPS2Loader
4. Activate in-game-reset (IGR) with L1+L2+R1+R2.
5. Launch CheatDevice again
6. Boot a disc or ELF with cheats enabled
7. Console will hang requiring a manual power cycle

Expected behavior The disc or ELF should launch with the engine enabled regardless of the environment state.
