Hacking Devolution - Public Release

[airline38]

r120 fixed the graphical display issue of "Need For Speed Hot Pursuit 2".
It's great !!

 

[tueidj]

The texture problem is mentioned in the first post, I will work on it when I'm ready and there's no need to report any occurrences of it - they are all symptoms of the same problem.

I did mention all the graphics issues were related, so all rainbow/scrambled textures should be fixed.

For anyone interested, when gamecube games send the address of a TLUT (texture look-up table) to the graphics processor they send a single word that looks like this:
0x64XYYYYY
where X is undefined (random) and YYYYY is the physical memory address of the TLUT right shifted by five. The reason X is undefined is because the physical memory address will only use bits covering the range up to 0x01FFFFFF (GC only has 0x01800000 bytes of RAM), when you shift that value right by five it becomes 0x000FFFFF. The GPU knows only those bits are valid and ignores the rest, so the GXInitTlutObj function doesn't bother setting the value of X to anything (it will be whatever was left in memory before).
However in wii mode the presence of MEM2 means the physical address of the TLUT can be in the range up to 0x1FFFFFFF, which gives 0x00FFFFFF when right shifted by five. So the GPU does pay attention to the extra four "X" bits, causing bad values to be read into the TLUT caches. The patch I added ensures that the undefined value "X" is always zero.

r120 has apparently fixed all visual bugs for me as well(except in MGS, as other have noted). Very nice. Thanks for the great update, Tueidj!

Edit: Thanks for giving us some insight into how the fix works as well. It's always neat to hear about little tidbits like that. Once you discovered where the problem lay, it was a relatively easy patch then, by the sound of it?

 

[tueidj]

My patch changes one instruction from "load a value from memory to register X" to "set register X to zero".

 

[daxtsu]

Nice and easy.

Also, not that it really needs confirmation, but Metroid Prime 1 is no longer crashing at the pirate frigate, and the palette issues in both MP1 and MP2 are fixed, as I've noted in the Wiki.

I wish I had more games to test. A number of games in the wiki haven't been tested for some time.

 

[tueidj]

Uh, if people are going to update the compatibility list with the new revision number and notes like "palette issues fixed as of r120" why not just remove the "issues" label instead?

Although perhaps not very useful for end users, I find this sort of stuff fascinating. Always cool to get an explanation of a problem and how it was fixed. Will have to try some of the games which had corrupted graphics... expect that they will be fixed.

 

[Taleweaver]

Just tried Tony Hawk Pro Skater 3 (PAL) again. Works perfectly now.

 

[Benze]

tested crystal chronicles again and even the complete messed up graphics are fine now. audio is still garbage

 

[OneUp]

Army Men Sarge's War (USA) doesn't work currently. It black screens after the publisher logos.
Log: http://pastebin.com/DkxSqyXE

 

[wiismodrome]

Cars has issues playing the intro video (intermittent freezing in video/audio) and locks up with a black screen when the game is started. I'll see if I can post a log later sometime.

 

[thevoiceover]

" - enable paired singles instructions before launching (fixes Midway Arcade 2)"

So, this part in some of the fixes seems to have worked great for not only Midway Arcade 2, but 1 and 3 seem to work properly now... So now Midway Arcade 1 - 3 work (The whole Midway Arcade suite.)

Now time to go through and correct the compatibility chart for many of the fixes in the games I have, Great version update, the core/foundation seems pretty impressive now.

I wish I had more games to test. A number of games in the wiki haven't been tested for some time.

I'm updating a few now... Question though @tueidj - If we already submitted bug on earlier version and things such as textures are fixed now but other issues remain (such as audio) would you like new debug log or does the debug info remain the same on newer versions and you do not need this?

 

[Joel Schmidt]

EDIT : Just googled it.

is this thing legit?

Whoa! I've never seen one like that before. That thing is ridiculous!
The only Gamecube keyboard that I've seen is the Datel Sharkboard,
which is basically just a PS/2 keyboard to GC adapter with an included keyboard.

It is very legit. I have one..... but it is VERY bulky and not worth the headache.

 

[thevoiceover]

I wish I had more games to test. A number of games in the wiki haven't been tested for some time.

I'm pretty sure games that have been added to the wiki are gone now, I remember adding a few games that are no longer there (I think Lost Kingdoms, Muppets Cruise, Gun being some of them.) Are you aware of this? I just hate having to do more work for this (adding and testing / making images to test again)!

 

[tueidj]

I don't recall seeing entries for those games.

Who changed the memcard status for tony hawk 3 US to "no" but put "works perfectly" for the notes? How can it work perfect if there's an issue with memory card emulation (which I doubt) ?

 

[thevoiceover]

I don't recall seeing entries for those games.

NFL Street 2 locks up at intro / E.A logo boot with distorted audio. Muppets was random, thinking just bad coded game - like SMS

Who changed the memcard status for tony hawk 3 US to "no" but put "works perfectly" for the notes? How can it work perfect if there's an issue with memory card emulation (which I doubt) ?

sorry, that was me. first time editing the wiki... fixed now

 

[ToddofWar420]

@[member='tueidj'], Thanks for fixing the palette issues for Super Smash Bros. Melee. It's just what I was waiting for!

 

[Bryon15]

All of a sudden it's taking games a really long time to load for me. When I go into devolution and press A to start a game I get a black screen for like two minutes. And then the game loads. It wasn't like this before. It used to take a couple seconds. What happened?

 

[OriginalHamster]

Nice, Capcom VS SNK 2, and MegaMan Collection works flawlessly now
