I tested some RPCS3 versions and found out that this is a regression from version v0.0.30-16063-65d93c97 (PR #13897).

Here are some logs :3

Regression (v0.0.30-16063-65d93c97): RPCS3.regression.log Working (v0.0.30-16061-85f4c38b): RPCS3.working.log

Use Accurate XFloat

[uhwot]

@AniLeo Using Accurate XFloat causes other physics issues which don't happen on Approximate (like stiff springs not working properly), so the same level is still unbeatable even on Accurate

[RipleyTom]

Is it still an issue?

[uhwot]

@RipleyTom I just checked on latest (v0.0.30-16110-e3d4c067), yeah this is still an issue

[atmospho]

So we're just unable to play this level until it's resolved? I ran into a similar issue in LBP 1

[BillQuain]

I did a little testing of that level as I am having the same problem. And what I found out after looking at old footage of the game and what was happening in my emulated game is that none of the gas effects in the level are working correctly, (score bubbles, gas vents on the train at the start of the level) also the monsters explode in a much more violent fashion compared to ps3 footage. I don't know what setting would effect this.

[Adeladen]

Tried with every XFloat setting, none of them fix it. Is there a way to cheat past that segment or is the only option to wait until it's fixed?

[Pixel3000nerd]

@Adeladen As far as I know there's no way to cheat past the segment. Have to either wait until is fixed, or downgrade RPCS3 to the last working version (v0.0.30-16061-85f4c38b as reported by @uhwot )

[uhwot]

Still an issue on 0.0.31-16215-3393d13b

[GalaxyGaming2000]

Still an issue on 0.0.31-16215-3393d13b

for now just downgrade to rpcs3 v0.0.30-16060 for this level only

yeah this worked for me, the guide to using older versions didnt work though i had to copy my new version files into the older version's folder and it saved my progress then and worked through the entire game in old build

[AniLeo]

Still an issue

Please provide a savefile.
