Sherlock Holmes Consulting Detective freezes #94

Closed ualaa1 closed 1 year ago

Freezes at the beginning. It can happen any time, but the way I triggered it the most was by choosing English mode and selecting introduction, where the game immediately freezes. I have tried various ways to avoid the freeze, including slowing down and speeding up the Cpu, adding more and less ram, and enabling and disabling the FPU, but the game will still freeze sooner. Output log:

Sherlock Holmes Consulting Detective assumes CD-ROM drive to be 1X. The pre-fetch function overruns the buffer if the CD speed is faster. Can you try CD-ROM 1X speed?

Thanks, it seems to work. Haven't encountered any crashes so far.
