[REQUEST] Call of Duty Black Ops Declassified

[3750gustavo]

can you check if there is any thing that can be improved on declassified since besides killzone it is the other biggest online game on ps vita that still have player base. and about helping you could you release a guide of things we gamers and starters on programing can help you improve your plugin faster? see if i could i would love do myself the request about cod and sent you what i found,but i downt know. i have basic knowledge about c and java programing and some other stuff.

Rinnegatamante wrote a nice guide for vitaRescale: http://wololo.net/talk/viewtopic.php?f=65&t=48713 But, it requires you to have IDA Pro (which might be hard to obtain legally due to it's cost).

Here is one for prxtool (which is free): https://pastebin.com/raw/mwzYECTm (only look for MOV/MOVS and MOV.W/MOVS.W)

I was only able to lower the resolution on Call of Duty (runs at 720x408 by default, crashes at anything > ~720x415). 60 fps uncap is possible, but it fluctuates anywhere from 30 to 60.

O think 50 fps would be great for a more smoothly control with the Vita analog stick

I have no idea how you're supposed to find the offsets for games that use sceGxmColorSurfaceInit to handle their IB just by searching for the plain values, especially when the instructions you shared for P4G (which I assume uses sceGxmColorSurfaceInit) doesn't use "mov-" instructions. What are you supposed to do for those kind of games?

[Electry]

P4G has resolution stored as plain float values in DATA section. Here is simple converter: https://www.h-schmidt.net/FloatConverter/IEEE754.html

We're patching 00005244 0000EE43 to 00007044 00000844. Because of ARMs endianness the bytes are stored backwards (so 00005244 -> 0x44520000 == 840.0f).

[Electry]

Another VRAM heavy game, that's why it crashes if you only increase the resolution. I got it running at 840x476, but it drops under 30 very often.

[nad45]

I suppose it will be the same situation with Resistance, as they both use the same engine.

please, would you have the patch available at 840x476?

[Sal-gamer]

@Electry this game has RAM memory left, could you redirect the VRAM memory to RAM when the RAM ran out? to use RAM as shared memory with VRAM?

[SheidCraft]

@Electry there is still a resolution of 780x442, you can try it

[Sal-gamer]

@Electry ainda existe uma resolução de 780x442, você pode experimentá-lo

a resolução nativa é 720x408, certo? teria disponível este 780x442 ??

[juliansteenbakker]

I was only able to lower the resolution on Call of Duty (runs at 720x408 by default, crashes at anything > ~720x415). 60 fps uncap is possible, but it fluctuates anywhere from 30 to 60.

Does anyone know if its stored as MOVS.W instruction? I cant seem to find the adres for it. Same goes for #29 Resistance Burning Skies which is probably running the same engine.

I figured out how it works and while i was able to boost up the resolution AND the fps for Resistance: Burning Skies #29 , I'm only able to unlock the FPS for this game. I will keep trying but in the mean time here's the patch for it:

I would really like to hear from you how you achieved this without crashing the game. @Electry

[MatthewL2019]

fps and resolution patch for call of duty Declassified can run max res. of 961x415.

So I decided to work on vitagrafix patches for nihilistic games.Before there was only semi-working patches and only for US versions. What weve got in total: Now you can cap Cod to FPS=60.But problem is that they barely achieve 40 FPS. Things is a little bit complicated with Call of Dooty.This game refuses to accept any height more than 415.That mean you can play with any width and height of 415.Maximal width is 1024.If you want to achieve native resolution, well, you cant.Set 961 (not 960) by 415 and enjoy. Maximal resolution is 1024 by 415. Sample config: (better set this resolution) [PCSB00232] IB=840x415 FPS=60

CoD BO Declassified [EU Russian 1.02]

Max recommended is 961 x 415

Hey, Thanks for the Resistance one and this, I'll try it myself!

[MotoLegacy]

fps and resolution patch for call of duty Declassified can run max res. of 961x415.

(US 1.02) Necro-posting to add more detail here. 960x415 does indeed allow the game to launch however it crashes when trying to load any level. Likely due to what Electry (won't tag because I'm not trying to seriously revive a 4.5 year old conversation) stated as being VRAM allocation issues. The 415px height limit seems heavily imposed.. Attempting to go above that regardless of width causes a crash at startup. This really holds back attempts to sharpen the game up.

The highest width I was able to get from the "Winter Break" Hostiles mission was 959px (ironically just a column off from what was initially reported):

This illustrates quite well another problem with the 415px height limit as well, the fact the viewbuffer becomes very obviously stretched making things disproportional. You get a (barely receptive) crisper image at the cost of uneven axes and lower precision when aiming.

A width of 736px properly accommodates the height limit:

I've found a width of 840px is the best middleground:

And for the sake of comparison here's the default viewbuffer size of 720x408 so you can gauge whether or not altering the resolution is worth your while:

Here are the percentage numbers: 959x415: 26% resolution increase (25% width, 2% height) 736x415: 4% resolution increase (same aspect ratio) 840x415: 16% resolution increase (15% width, 2% height)

Regarding framerate, the game is CPU bottlenecked in multiplayer so you'll top off right above 30 fps on average but can get ~45 in select scenarios, regardless of resolution. This can give the opportunity for better precision/higher response time when aiming shots. It's definitely sporadic but very playable. In singleplayer lowering the resolution down to 25% (480x272) can allow the framerate to reach a 60FPS target in most occasions. Super smooth there.

=========================== TLDR: Resolution bump is kinda a bust overall, degrading resolution has nice effects in Singleplayer. Increasing FPS limit in Multiplayer only really useful for higher input response time.
