Jagged characters in Ys 3 (Japan) #37

Closed farsil closed 7 months ago

farsil commented 7 months ago

Hello,

I have noticed that, compared to the Genesis core, the characters from the Japanese version of the game look jagged while they walk, as if there was some interlacing issue:

What could cause that? Is it a setting on my core or is it a bug in the emulation?

I can provide the ROM hash if necessary.

Thank you!

Are you sure it's ok or real HW?

I can't see your other message in this thread, but it was delivered by email. I was not aware of the workaround. Unfortunately I don't have a Japanese MD to test the issue myself.

Thank you for giving me some context on the game bug and for maintaining this core.

because i messed with Ys on SMS :) It had different problem with broken panel on bottom. So jagged look is completely different thing.

I can't reproduce this in the core. I suspect it's something to do with your display device upscaling the core's output.

I tried on a new save file and I cannot reproduce it either. It may have something to do with my current save, which is imported from the Genesis core. I thought the two save file formats were identical, but maybe there are subtle differences?

At any rate, I'll close this for now, thank you for taking the time to address this GitHub issue.
