I know that anyone that reads this part is going to think im nuts and hasnt got a clue what they are talking about, but I believe Ive figured out the reason for my stutters, but not how to fix them.
Its sound related.
Hear me out.
Alundra - the stutter is easy to see when going left to right accross the screen, in the opening area once the game starts proper. Whats not so easy to spot, is that the stutter is linked to the sound. A couple of drum beats and symbols that play at the same time, cause the video stutter. Its that accurate, I can now predict where the stutter comes in, and it does , 100% of the time.
So I thought then that this may be an issue with SD card read speeds etc. But again, provided you are in a PS1 game that doesnt require a load (Alundra, you can run around the village, with the music and sound effects playing) without loading. So all of that must sit in memory. You can test this because you can remove the SD2Vita, and the game will carry on playing, and continue to stutter in the same place, due to sound. So it cannot be an SD issue? I think, although im no expert in the slightest, that video stutters, are caused by sound. At least in my case!
But it would be nice if people could test what ive tested, to see if they dont get it.
