Custom Resolution in Uncharted 4
Please note that you are required to have a exploited PlayStation 4 console on firmware 9.00 or lower to run the patches mentioned in this article.
Intro
This will be a short one due to how easy it was to patch. For those who expected a long in-depth post, sorry!
I have always wonder if the resolution can be tone down in Uncharted 4, would 60FPS be possible? Short answer is No. But in the future on the PS5, very much of a possiblity.
Research
For starters, resolution numbers is stored as 4 bytes. At least in Naught Dog games. A quick search for 1600
and 900
in one row shows one result . Why 900p? The multiplayer modes switches to 900p during gameplay.

012cf21c 48 8d 88 LEA RCX,[RAX + 0x3c0] // add 540

012cf22a 48 b9 00 MOV RCX,0x21c00000500 // 1280x540 for split screen

012cf23b 48 89 83 MOV qword ptr [RBX + 0x7d80]=>DAT_02bde530,RAX // load from rax into memory
80 7d 00 00
012cf242 48 89 8b MOV qword ptr [RBX + 0x7d88]=>DAT_02bde538,RCX // load from rcx into memory
88 7d 00 00
012cf1f2
is what we are interested in.
40 06 00 00
1600 in 4 bytes.
84 03 00 00
900 in 4 bytes.
Patching this to 960x540 is as simple as swapping out the existing numbers with our own.
C0 03 00 00
960 in 4 bytes.
1C 02 00 00
540 in 4 bytes.
That’s it!

1c 02 00 00
