XBOX DEV/128ram I need your HELP !

Hello guys !!!

I need some help, does anyone here have a devkit and/or an upgraded xbox with 128 ram ?

I will need to make some comparison between those 2 systems, It's really important, I have proof that these 2 systems perform differently when playing in 720p.

If you want to participate and help to demonstrate or resolve the question about the difference of performance between those 2 systems, you must fill and answer on this questionnaire:

And then You need to take either Project Gotham Racing 2 PAL or OTOGI PAL (or the 2 if you can/want):

Send me a PM for links if needed

Then download those XBE 720p hack:

OTOGI 720p .xbe
PGR2 720p .xbe

And for help, use the full save on PGR2

PGR2 save 100%




Here an example of mine:

Thx in advance, this is really important !


EDIT: here more info of what I'm doing:

How are we supposed to be able to tell what FPS everything is running at? Is there a way to turn on an FPS counter on Xbox debug kits?

 

Unfortunately not (well I don't think) about a FPS counter on xbox devkit, I did "estimate" them, since I usually do a lot of comparison with PC games and Emulator (with FPS show).

But I don't really ask for a precise number, just what you think about the "playable" state, knowing that 15 fps is almost unplayable, 20 is playable but with some slowdown, 25 is good enough, off course everything under 15 fps mean completely "unplayable" even the input have some serious latency (like OTOGI stage 2) .

I can maybe make a video (with my phone *sight*) to show what it usually the latency we can have.....

 

You don't have to make a video, I think I understand what you're saying. I'm willing to participate in this, but since my debug kit has never been opened (and I don't ever want to), how can I tell what brand the ram is? It's a debug that came with a 10gb HDD in it, so I think it's a different version to most. And also, should I run the game through UnleashX or the normal debug dash? I've got both installed.

 

If its a debug kit, then you must have a Samsung RAM (only last revision got Inyx, I think).

Same, don't hesitate to try both Dash, also, if you can't complete the questionnaire, no prob, better to have the result and then investigating later than the inverse. =)


Thank you for you help !

Here a video of someone using my .xbe patch on a debug kit -->


As for me, I have a lot of frame drop in the Hong Kong map, I need to mod some .ini to switch the maximum view distance from 3000 to 600. =[

 

That someone is me btw

 

one question maybe stupid, is it possible for all games, like Outrun 2 or some of their....

 

Wo ! nice to meet you !

What did you use so ? a devkit ? did you get any lag input on this race, or any race at all ? because I bought a 128ram upgrade xbox, and I get some huge latency on this race (well on hong kong mostly).

So what did you have on your xbox (dash, bios ?) that can make a so huge difference in performance ?

EDIT: I have hex edited another game, Otogi, don't hesitate to test or even make a video if you can http://assemblergames.com/l/threads/zaykho-720p-1080i-hex-edit-master-thread.57847/

Yup, it all depend of 2 things:
1) does the game is optimized enough to get stable 720p ?
2) if no, does the game let the "hacker" optimize things by .xbe or even data files ? (like pgr2 that let you choose your maximum view distance, or Otogi with .xbe that let you choose to avoid rendering shader, texture, fog etc...)

 

I believe I used my debug kit, been a while. I dont recall the input lag being an issue, but I could double check. Standard debug bios launched from XShell.

 

Ok, so that mean I will need to buy a Devkit, I will probably buy one and a Trusty CPU + RAM too, to test everything in the optimal situation !

 

Im having no luck with Otogi thus far, only seems to boot in 480p (and yes, Widescreen and 720p are enabled). I had issues not being able to get a 720p version of the Lamborghini demo to boot too.

 

Ah yeah, its normal, for otogi I did experimented something, in fact, the Anti Aliasing method used by nvida on the XBOX is a fullsreen rendering method (and not per distance).

So, to optimize this, they have put a "switch", saying that everything rendered in progressive (have half the percentage of AA) and, if anything is rendered in 720p or more (including 1080i), the AA will be disabled.

That's why, when you play in 720p in Xbox Original or XBOX360 Back.comp, you have no AA enabled.

But, if the native resolution of the game is in 720p, and the output buffer is in 480p, the xbox will think that the game is in 480p and will apply the lowered AA. For that, you need to check 480p and 720p on the dashboard with the OTOGI .xbe. (if you try then to launch with only the 720p, you will see the big difference between AA off and on)


Now about this, if you did launch the first stage of OTOGI, you did see that the character is on the Bottom right instead of the center, right ? that's normal (Its the tricks I was talking about), but if you take a screenshot with the XBOX devkit, then, the xbox will take only the native resolution instead of the final rendered screen, you will see the entire scene in 720p. (that's why you never see any AA in devkit pictures, also, some games like DOA3/X use strong AA and color Saturation in final rendering scene [something that Dice use a lot in Bf3 nowadays])


in short, normal game is rendered like that:
native screen : 480p
+
Effect render : 480p

what I did is:
native screen : 720p
+
AA render : 480p

 

The problem is 720p isn't working at all Edit: I see what you mean now. That is weird. Strange that it isn't really outputting 720p then.

 

Yeah that's why I did try this, maybe tonight or tomorrow (france timezone), I will fix it and render this exactly like pgr2.

About PGR2, I never take the time to finish the hack, but I know how to fix the HUD, more than that, I can make any tree more beautiful, (the leaf tree in PGR2 are a simple texture rendered in front of camera, the game use a percentage of the resolution screen to render a certain amount, if you set to 2048 or even 4096 in texture percentage, you get a damn big tree =) hahaha)

At the moment, the only one very hard to get work in 720p is the DOAX, the menu screen (where showing the island, is pretty heavy)...


But the most important, can you try the stage 2 in OTOGI ? what is it about performance ?

 

See for yourself It may take a few minutes before it shows up, it is still processing.

 

Wow damn nice !!!

As for me, the game is damn slow (almost 5 fps, took me 1 minute to get in front of the house), and still, I only get a bad framerate on this stage, wtf ?!

It will be interesting to know why the devkit is more powerful than an upgraded xbox, strange......

EDIT: I'm fixing the output buffer right now

 

Try running MameOX128 or whatever before launching. Some people had issues with Virtua Cop to where the Xbox didnt initialize the extra ram right on boot for some reason.

 

Ok I'm trying

YES YES YES !!! it works !!!

The stage 2 is going well =-) some frame drop when destroying walls in the building, but the game is running great !!! Thank you !!!!

 

No problem

 

If you have any games you want to have in 720 forced, don't hesitate to ask !
