ahhhhhh
infinity nikki has the same anticheat as strinova
so, once again, compatible with steam deck, but not general linux
game companies, im getting really frustrated with not being able to play games on my nice GPU
@ashten I'm completely confounded by companies whitelisting the steam deck on Linux, and *only* the steam deck
It's just immutable Linux ! It has the same attack surface as regular arch !!!! Linux cheaters are a fraction of a fraction of a fraction come onnnn

Linux cheaters are a fraction of a fraction of a fraction come onnnntrue but also some of the more invasive cheats are on linux. So on one hand you have a few hundred people using really bad cheats, and the other you have thousands of people using passive cheats.
it ends up being the same, it's just easier to get rid of linux.
i wonder if they just check for APU identifiers, because then you can just install any other linux OS on the deck and bypass it. considering dedicated cheaters spend several thousands on DMA cards, i wouldn't surprised if they'd just buy a deck instead since that can also double as a pi for a DMA.
@natty@astolfo.social@ada@zoner.work @LiquidParasyte@pawb.fun [astolfo.social] @ashten@woem.men [astolfo.social] can't wait for anticheats in 2038 requiring encrypted RAM sticks or something

@natty@astolfo.social@ada@zoner.work @LiquidParasyte@pawb.fun @ashten@woem.men Did they just, make it access ACPI now
*Ada - Np-93/237 @ada@zoner.work@natty@astolfo.social @LiquidParasyte@pawb.fun @ashten@woem.men it's just a custom boot splash but the fact they're even joking about this means it was brought up at some point which is scary
@natty@astolfo.social@ada@zoner.work @LiquidParasyte@pawb.fun @ashten@woem.men Yeah but like
I think the logo Windows shows during boot is controlled by ACPI?
*Ada - Np-93/237 @ada@zoner.work@natty@astolfo.social @LiquidParasyte@pawb.fun @ashten@woem.men in 11 it's just the uefi boot logo since it gets written to a fixed physical memory address.
*Ada - Np-93/237 @ada@zoner.work@natty@astolfo.social @LiquidParasyte@pawb.fun @ashten@woem.men this is why grub can sometimes stay on screen after booting into windows, because they're writing into the uefi gfx address
@natty@astolfo.social@ada@zoner.work @LiquidParasyte@pawb.fun @ashten@woem.men https://learn.microsoft.com/en-us/windows-hardware/drivers/bringup/boot-screen-components Microsoft has docs about it somehow
*Ada - Np-93/237 @ada@zoner.work@natty@astolfo.social @LiquidParasyte@pawb.fun @ashten@woem.men wdym somehow they wrote uefi and acpi
@natty@astolfo.social@ada@zoner.work @LiquidParasyte@pawb.fun @ashten@woem.men Kinda out of character for corpos to make it freely accessible
*Ada - Np-93/237 @ada@zoner.work@natty@astolfo.social @LiquidParasyte@pawb.fun @ashten@woem.men make no mistake, they got threatened with a lawsuit over not disclosing it.
@natty@astolfo.social@ada@zoner.work @LiquidParasyte@pawb.fun @ashten@woem.men So they talk to the fucking UEFI 
*Ada - Np-93/237 @ada@zoner.work@natty@astolfo.social @LiquidParasyte@pawb.fun @ashten@woem.men i'm p sure this person just flashed a new bmp into the the motherboard bios
*Ada - Np-93/237 @ada@zoner.work@LiquidParasyte@pawb.fun @ashten@woem.men also as an aside
why tf do pve gacha games have anticheat
> i wonder if they just check for APU identifiers, because then you can just install any other linux OS on the deck and bypass it.
i do have a deck running vanilla gentoo so i could try it out
*Ada - Np-93/237 @ada@zoner.work@navi@social.vlhl.dev @LiquidParasyte@pawb.fun @ashten@woem.men strinova is free on steam, the launcher works on regular linux but actual game exits with an error dialog
vanilla gentoo with gentoo-kernel, no valve forks of any drivers or other software (except proton)
they're just looking for some hardware string or some shit
i'll ltrace and strace it later to find out
*Ada - Np-93/237 @ada@zoner.work@navi@social.vlhl.dev @LiquidParasyte@pawb.fun @ashten@woem.men cursed, it's just a placebo fix then
i'll do a funny, find what libc call they use to query that and spoof it with a LD_PRELOAD'd version
apparently the anti-cheat uses the cpuid asm instruction which i can't spoof (there's a hacky way to using an intel only syscall, but i only have amd machines)
@navi@social.vlhl.dev @ada@zoner.work @LiquidParasyte@pawb.fun
(i dont know what im talking about)
but would it be possible to patch the thing in memory so that it also has your current system's cpuid allowlisted?
*Ada - Np-93/237 @ada@zoner.work@ashten@woem.men @navi@social.vlhl.dev @LiquidParasyte@pawb.fun that'd likely trigger the anticheat's integrity checks. besides, patching anticheat out is not the wine way and instead should try to get compatibility with whatever api it's using
but this is a case of specifically blocking linux so there's not much to do here.
*Ada - Np-93/237 @ada@zoner.work@ashten@woem.men @navi@social.vlhl.dev @LiquidParasyte@pawb.fun besides of course, breaking the anticheat, which doesn't help the defense of linux is not for cheaters
at least we now know this is fully a hardware check, independent of the os (since it uses cpuid asm)
which means valve will probably have to do something against considering they're pushing for having many vendors for steamos
*Ada - Np-93/237 @ada@zoner.work@LiquidParasyte@pawb.fun @ashten@woem.men no because we have full control over the kernel, and injecting a kernel module requires being GPLv3.
