With all the games I looked at, I haven't found any new VFilters.

XFlak · Apr 25, 2021

Just a suggestion, but maybe keep editing one post to contain the complete list, then when you update it just post that it's been updated with a link to wherever the updated list can be found (similar to how Blackbox handles his usb loader gx updates)

Remember we also need to know Rev# and Disc#, which can be discovered with

Code:

wit ID8 --source "C:\Games\game.wbfs"

Output is: [ID6] [Disc].[Rev]

--------------------- MERGED ---------------------------

Would anyone mind testing the GCR command line extraction of SystemData\start.dol.

GCR 1.1 is available here , and the command is something like

Code:

gcr "C:\Starfox\game.iso" "&&SystemData\start.dol" "e" "C:\Starfox"
gcr "C:\Starfox\game.iso" "SystemData\start.dol" "e" "C:\Starfox"
gcr "C:\Starfox\game.iso" "\SystemData\start.dol" "e" "C:\Starfox"

I really need to know if it works or it's just my system.

NoobletCheese · Apr 29, 2021

It seems the author of GCR has gone walkabout, so I guess the command line is not going to be fixed.

I looked at its source code and its main(String[] args) bit looks fine but it seems to not be initialising the node path object properly or something, I can't really tell.

Not to worry -- after patching start.dol, the user can be asked if they want to launch GCR's GUI, and the command line for doing that still accepts the ISO image as an arg. From there it's only 3 clicks for the user to insert the patched start.dol and no rebuilding required.

Plus not many GameCube games need patching, so it's not like hundreds of games are going to be run through this process, unlike Wii.

I'm burning the midnight oil to get the tool finished, but I keep getting bogged down in excruciating minutiae. Sometimes my brain just cannot get into gear either. 10 days to completion was a pipe dream, sorry about that.

The main.dol scanning process is quite CPU intensive. It has to look at every single 7-byte sequence in the ~5MB file, and to speed this up it needs multithreading, which AHK doesn't normally support. Someone made a .dll for it that can do true multithreading. I can also speed it up dramatically by scanning only sections around where GXRModeObj's are found. It seems that all said objects are in the last 25% of the file anyway, so you could even get away with scanning just the last 25% of the file (or the first occurrence of a GXRModeObj in the file minus ~250kB, whichever comes first, with an optional 'quick scan / full scan').

XFlak · Apr 29, 2021

3 extra clicks is still too many

Having your script auto-click GCR's Gui to accomplish the same thing would be preferred IMHO, but as you said there are probably only a few cases where this would be applicable so I understand if you feel it's not worth the effort

Maeson · Apr 29, 2021

It is true that every hex strings are located at last quarter of main.dol, but each main.dol has a different size, they can go from less than 2mb to over 8mb, and there can be quite a difference in bytes from the end of the file to where the edits need to be done, so you might need to expand those 250kb, but yes, last quarter of the file is a sure bet with all the games I've looked at.

I wrote down the filters for more games, I have around 80 games. I also went and check them with WIT to have their disc/version data too. Most of them were 00.00 which I expected. I'll see how I share them later.

I did not point it out but looking on the previous page of this thread: Yes, some Wiiware games and VC games receive updates, but fortunately the are pointed out on the files names when you look for lists of Wiiware games. Like, I don't know, "Star Fox 64 Rev 3" or "Gradius ReBirth v257". There are not many of them, fortunately.

Edit:

Here's a drive link to a text file with all the games I looked at. But because the text viewer in it makes it look unorganised, I'll also put them here on a spoiler code like before, and I'll keep adding to this particular post if I get my hands on more games.

I also went ahead an listed them alphabetically.

        For some reason I cannot fathom, the
        PAL release has worse frame rate than
        the NTSC US one, and it has nothing to
        do with 50Hz/60Hz by the way, the European
        release just drops frames much more.
  
        Maybe that's why the NTSC US is Rev 1?

              I know that the first release, 00.00 had a
              glitch and this version fixed it up, that's the
              difference.

I wanted to add, that while Resident Evil 4 has noticeable dithering when removing the filters, it still looks better to me, and specially on 16:9, as what the game does on that setting is to zoom in into the original 4:3 viewable area, which made it look HORRIBLE, with huge pixels and extreme blurriness. With filters removed it looks much more acceptable to me.

Yes, some Wiiware games and VC games receive updates, but fortunately the are pointed out on the files names when you look for lists of Wiiware games. Like, I don't know, "Star Fox 64 Rev 3" or "Gradius ReBirth v257". There are not many of them, fortunately.

It seems WadDataInfo.exe (included with wwpacker) can extract the version from a wad:

Code:

Path: '00010001\57523945'
Type: Channel Title
TitleID: 'WR9E'    Version: 1    ManufacturerID: 08
IOS Flag: IOS37    Region Flag: USA
Data files: 11
Size: 8536331 - 15840913 byte (66 - 121 blocks)

If you could confirm your wads are populating the above value as expected, that would be helpful.

edit: have confirmed Gradius Rebirth v257 and Cave Story v258 are being detected correctly.

Here's a drive link to a text file with all the games I looked at.

Is this correct:

Super Mario Strikers Charged
R4QE01 00.001 NTSC US

I was expecting it to be 1-byte (2 hex digits) i.e 01.

Turning off dithering may not necessarily achieve a better result anyway, as the SDK says dithering can only be enabled when the game's pixel format is 5-bit or 6-bit per subpixel. i.e if you turned off dithering, you may then have very unsmooth gradients (banding). GameCube version should be better.

Sorry, there's one zero more there, it is 00.01, I will correct it once I get to my computer.

I haven't played the GC version of RE4 in over a decade, maybe I should try if it looks the same out of curiosity, but I can't imagine being different (6th gen games that wanted to look more detailed used quite a bit of dithering, ps2 did it often). In any case the Wii version has a number of things over that release so I don't mind it much.

I checked my WADs with wwpacker and everything seems correct regardless of what the version is.

Code:

Gradius Rebirth - v257

Path: "0001001\5747450"
Type: Channel Title
TitleID: WGDP  Version: 257  ManufacturerID: A4
IOS Flag: IOS55  Region Flag: Europe
Size: 26905765  -  30190447  byte (206 - 231 blocks)

It also easily recognises between the different releases of Star Fox 64.

I'll try to find the games that got updates if it's important. I know that a number of "apps" such as Amazon Instant Video or BBC iPlayer did get many updates throughout the years, but I think they won't work anymore, and who knows if they even used filters.

NoobletCheese · Apr 30, 2021

It seems pastebin will not be sufficient for keeping the master list of vfilters, as it has a file size limit of 500kB. I considered keeping each game in its own file, but pastebin doesn't disclose the maximum number of files per user, and I think there's a limit. There is also a limit of 20 uploads per day.

Google Drive's API seems to be unsuitable as it requires each user to manually verify their device at google.com/device before they can remotely upload to the account using something like curl at the command line.

GitHub Gists have a max file size of 1MB and max file count of 300 according to their docs -- still not enough for our needs.

Regular GitHub repo files have a max size of 100MB and GB's of total storage, so they will be sufficient, however there doesn't appear to be a reliable API for pushing files remotely from any computer. The problem is not the git command line but rather getting authentication for the git command to work, which seems to require tokens now according to a recent change in Github policy. This may be possible with curl, but I'm not confident after reading some anecdotes.

The best I can currently do is have a button that copies to clipboard the selected vfilters, and then the user has to manually log in to the github repo and paste them in. I will try to automate this but I'm not hopeful.

If anyone knows of any other large enough cloud storage that can be accessed with curl, please let me know.

U can upload to github manually if u really wanted, through your browser or non-cmd line tools. And you can download with a script easily without credentials using wget or curl

For uploading I've decided to go with Google sheets as it allows automating things like validating the pasted data, highlighting potential bad data, keeping track of which pastes have been validated, restricting data ranges to admins, and exporting to csv/tsv for upload to github for easy download as raw.txt by game loaders.

Such a shame as Pastebin was looking like the perfect solution. But I think one day they would just decide to change their API and then my tool is broken, just like GitHub is about to break many apps with their upcoming update.

Have you considered that you might be making this harder than necessary?

I can't read assembly, but are those RAM addresses being patched while the game is running?

Extrems · May 2, 2021

It's a replacement for the entire function. The executable is patched ahead of time in Swiss.

Ok, so that's basically the holy grail that we've been seeking

But how the heck does Swiss find the offsets for the function inside the executable? The offset might change depending on where the compiler happened to import it. Is there some byte signature that Swiss looks for? Or is this running on a custom OS where the whole system library is replaced with our own version of it?

--------------------- MERGED ---------------------------

Is this relevant:

https://raw.githubusercontent.com/emukidid/swiss-gc/master/cube/swiss/source/patcher.c

Code:

FuncPattern GXSetCopyFilterSigs[5] = {
       { 567, 183, 44, 32, 36, 38, GXSetCopyFilterPatch, GXSetCopyFilterPatch_length, "GXSetCopyFilterD" },
       { 138,  15,  7,  0,  4,  5, GXSetCopyFilterPatch, GXSetCopyFilterPatch_length, "GXSetCopyFilter" },
       { 163,  19, 23,  0,  3, 14, GXSetCopyFilterPatch, GXSetCopyFilterPatch_length, "GXSetCopyFilter" },   // SN Systems ProDG
       { 163,  19, 23,  0,  3, 14, GXSetCopyFilterPatch, GXSetCopyFilterPatch_length, "GXSetCopyFilter" },   // SN Systems ProDG
       { 130,  25,  7,  0,  4,  0, GXSetCopyFilterPatch, GXSetCopyFilterPatch_length, "GXSetCopyFilter" }
   };

NoobletCheese · May 2, 2021

Structure of GXSetCopyFilterSigs[]:

Code:

typedef struct FuncPattern
{
   u32 Length;
   u32 Loads;
   u32 Stores;
   u32 FCalls;
   u32 Branch;
   u32 Moves;
   u8 *Patch;
   u32 PatchLength;
   char *Name;
   u32 offsetFoundAt;
}

It looks like the first 6 elements are the ones we're interested in, but I have no idea how they translate to raw bytes inside main.dol.

I'm guessing Length is the length of the byte pattern.

Loads, Stores, FCalls, Branch and Moves are unfamiliar to me -- do these correspond to assembly instructions?

If true, does that mean the patcher isn't actually looking for a discrete byte pattern, but rather a pattern which contains a certain number of assembly instructions?

NoobletCheese · May 2, 2021

Assuming what I wrote is true, I would need to know the raw bytes that correspond to each assembly instruction, especially the ones that correspond to a function prologue/epilogue so I know where to patch the new replacement GXSetCopyFilter. I suspect this is defined somewhere in Swiss source code, but I haven't found it so far. If it's defined programmatically then I probably won't understand it

Being able to identify a function prologue in the raw bytes would also seem to speed up the patching massively, as the main patching loop could just ignore bytes until a prologue is encountered before searching for the signature. I'm guessing this is how game loaders like Swiss/Nintendont/ULGX etc. are patching the DOL in mere seconds, whereas my tool takes about 30 seconds just to scan the last 25% of the file for the vfilter signature. Perhaps I can speed it up by ignoring byte patterns that don't correspond to whatever the assembly code is for storing a u8 vfilter[7].

Honestly though, this would be a huge amount of work for me to learn assembly, and there could be a number of Nintendo-specific caveats I'm not aware of that could break my attempt and I could get stuck. I think I'll leave it to the experts who already have years of experience with this to decide if they want to implement Swiss's GXSetCopyFilter patching into a Wii game loader. If this happens, then we don't need a cloud database. As there is no harm in also having the database, I'll not abandon it just yet.

NoobletCheese · May 3, 2021

It just occurred to me, we wouldn't have to store in the database any entries which use the standard Nintendo vfilters (08080A0C0A0808 and 04080C100C0804) as those strings are unique enough for the game loader to simply 'find and replace'.

Although there might be some edge cases where such byte patterns exist which happen to be other game data, the game loader can choose to only patch them if they have an adjoining GXRenderModeObj, i.e preceded by 060606... or 030209...

If there are some rare edge cases where the game sets a standard vfilter without referencing a GXRenderModeObj, then it can be added to the database.

The upside is that the database is probably going to be around 95% smaller, which is great as Google Sheets bogs down with very large sheets, and pastebin might be feasible again.

Apologies to @MaeseJesus for all the hard work you put in which probably won't get added to the database
