// Redirecting the emulator's IO read perform pointer allows us contact an arbitrary handle and get back what ever eax holds right after it returns
DiavoJinx claimed: I actually ONLY want to be able to pop in one of my PS2 discs and Perform it on my PS5.

Sony has steadily expanded the collection of common video games obtainable on the PS5. Down below are notable PS2 titles both verified or rumored for arrival about the PS5:
It had been intended in this way since PlayStation can't be held to blame for the safety of third party video games (significantly the ones that statically website link to outdated variations of WebKit).
For the impatient, a demo video clip for the 1st part of the chain is presented afterwards in this post.
Here are some essential configurations it is best to undertake for yours. These may not Focus on all setups, so experiment a little bit or make reference to the PCSX click here two Web site and message boards for help as your knowledge might range.
I’m persuaded we’ll see much more cool PS2 things exhibiting up for this exploit in the days to return. Naturally, with small modifications, all of these releases must work on the most up-to-date PS4 firmware (10.01) as well.
But when I can down load PS2 video games and Perform them without needing to find the outdated disc or dusting off the outdated PS2, I'm match.
This could result in executing our major ROP chain, after which you can returning gracefully back to PS2 execution. Be aware that the main 3 measures are Component of the set up course of action that only needs to be completed the moment; to execute subsequent ROP chains we just need to write them over the last chain, after which execute them by composing for the pre-corrupted memory-mapped-IO handler (actions 4 - 5).
I haven’t appeared into this within a few years so possibly the options are superior, but final I checked the cheap upscalers tended so as to add a decent amount of lag. Whether/the amount that matters will depend on the game, but by way of example, I’d by no means need to Participate in a racing sport on any of the cheap upscalers I attempted.
Composing to that memory-mapped IO register now phone calls an arbitrary deal with with managed esi register,
Considering that this system wasn't compiled here with CFI enabled, this will permit us to then bring about a phone to our corrupted perform pointer by studying from 0x10000000, and the eax sign up will eventually be returned as the result again to our PS2 read through instruction; we'll call this Primitive three:
