Confirmed

#2 Updated by JMC4789 over 2 years ago

Setting the Emulated CPU Clock to 6% allows the game to proceed past the hang.

#3 Updated by kolano over 2 years ago

How does one do that, we only seem to allow 10% increments on Speed Limit?

#4 Updated by kolano over 2 years ago

Ah sorry, under the advanced tab. That does work but is too slow for the game to be playable.

#5 Updated by kolano over 2 years ago

It works at 50% CPU overclock for me, though I'm guessing the specific value is likely hardware dependent.

#6 Updated by leoetlino over 2 years ago

This is a timing issue. During the black screen phase, the game expects a game tick to take at least (TIMEBASE_FREQUENCY/1000) TB ticks (which means the TB tick difference must be greater than 0xed4e).

On Dolphin, the value is always around 0x7000 (<0xed4e) so the game never continues.

Downclocking the emulated CPU works around this cycle accuracy issue as it makes a game tick take longer to complete.
