I am not a github member, is it ok to post it here? For example, the sequence at the beginning of the game, when Lahan is attacked and set on fire, there is this very cool effect, like extreme heat haze. Beetle PSX HW renders the scene incorrectly, like so:
Decided to register on the forums since I’ve seen this twice now and . Here in this post (and the aforementioned github post) and here back in 2017:
Anyway, it’s apparently caused by Beetle PSX HW core options - “Renderer” being set to: hardware.
Setting said option to software, closing content (closing the game through retroarch), then re-running the game in software renderer mode fixes the issue but causes another bug by offsetting the SCE bios intro slightly to the left & up. Here’s a screenshot:
At least that’s how I figured it out. I tested all core options on & off one by one and that’s the only thing that affected it and made it go away. Also, might be an important factor: you can’t just switch the “Renderer” option to software then select “Reset/restart” in the command window or Quick Menu either. You have to close the game entirely then reload it again.
