[PS1] Fear Effect

[kivutar]

Describe the issue

Fear Effect is stuck in an infinite loop while decoding the first introduction video. This is due to bad timing in the DMA MDEC code. The DMA callback supposed to notify that blocks are done being decoded, is called too early. The interrupt happens before the game starts waiting on a boolean value in a while loop. This causes the game to be trapped in this while loop.

Rom Information
Specify the impacted rom filename and any associated hashes (sha256 preferred);.
The easiest way to do this is to open the game in ares, and go to "Tools -> Manifest" and copy/paste the contents.
