Hacking Devolution - Public Release

[tueidj]

It doesn't seem to run properly for me; I get a code dump when I select dump raw image, then slot A, with my 251 offical card:

I'm running it off a USB hard drive, if it matters.

Most likely Daco doesn't bother to check if the SD card is mounted successfully before using it. I only fixed a couple of obvious bugs in his code, if I were to fix them all it would take me hours.

I got the same result that Kupo got with a 251, the raw dump didn't write properly; it doesn't work in Devo nor Dolphin's manager, however dumping as separate .gci images does work perfectly.

2MB for a 251 block card is normal. Here's how to calculate the raw size of a card:
Each block is 8KB.
5 blocks are always reserved for system use, so add 5 to however many blocks the card claims to have.
59 + 5 = 64 * 8KB = 512KB = 0.5MB
251 + 5 = 256 * 8KB = 2048KB = 2MB
1019 + 5 = 1024 * 8KB = 8192KB = 8MB
2043 + 5 = 2048 * 8KB = 16384KB = 16MB.
If you hear a card being referred to as "64mb" or "128mb" it's marketing or advertising rubbish; they're referring to the number of megabits rather than megabytes. Divide by 8 to convert to bytes. There are no cards larger than 16MB, it is the largest size that games have code to handle. If your card is smaller than 16MB you should be able to use Dolphin's save manager to copy the savefiles from the dump to an emulated 16MB card, which can be used in Devolution. If somebody uploads some dumps from smaller cards I can try adapting Devolution's code to handle them.

I could have sworn I saw a post after this one a few minutes ago. Must have been a glitch in the matrix.

Tested with Devo r104.
-The raw file is 2mb
-I rename it memcard.bin and put it in the HHD/apps/gc_devo
-Boot gc_devo, mount HDD
-It says resizing memory card
-When I bootup a game, it say the memory card is corrupted
-I check the memcard.bin and it's 16mb now

I'm using a 251 official memory card

(4:09:42 PM) DacoTaco: can you quote tueidj and tell him that yes, ctr-gcs's code is shit. i made & released it in a quicky cause the wii scene bores me.
(4:09:52 PM) DacoTaco: but im open for fixes if anyone minds telling me the bugs
(4:10:04 PM) DacoTaco: tho a rewrite is really needed....but im so damn lazy

also tueidj, how can you live with all these ppl posting the same thing
over
and over
and over
and over

and not realise what is going on?

Sorry, I make a point of not taking advice from crazy people with multiple personalities.

Can I use a 1:1 backup burned on a DVDR instead of my original disc for the verification process?

 

[PsyBlade]

I didn't test it but it would kind of defeat the purpose wouldn't it?

It may be possible with a modchip.

Perhaps because he has learnt how a dev should treat users?

I guess he does understand... Other than just the typical "new one" (It is annoying reading x amount of times that this new memory card fix only works with 16MB cards (not any other size) and people continue wondering why theirs doesn't work when dumped), most of these people are just trying to annoy and/or say things to hurt b/c they are on either a different belief system, or just jealous. Pretty obvious how these get flooded with some of these messages with users saying the comments they say (many of which are new users just trying to hide their ident)

I have read way more than I care to post here, but I do know in my opinion Devolution is and if not now, will be beneficial for its additions alone. As long as tueidj continues helping the scene (for whatever cause it is up to him, but knowledge is just that and in my opinion if someone is helping me out, I will take it from where it comes) let him help out! He is finding bugs in way more code that has been out for years with no major fixes...

At one point I wasn't a father of 5, didn't have actual priority or direction so I too focused on at times making others look bad out of jealousy. Well, now with time I see overall, if that person was helping out in any way (whether I liked them or not) that the way they helped I used more for that time rather than the hate I may have had towards them (which went nowhere...)


Urrgh, frustrating though. On to Devolution! I am really looking forward to a newer release ASAP and hopefully some BT code (at least power toggle hint hint) or reset hooks.

Sorry, I make a point of not taking advice from crazy people with multiple personalities.

heheh. No wonder you aren't taking any of my advice on features

Official memory cards working and raw dumps are great news! I actually was working in adding raw dump support to GCMM 2-3 years ago, but for some reason I was never able to write the dump back to the card, my memory is very fuzy about the matter.

Now that this is solved, what about protected savegames (by the way, are there any others aside f-zero and pokemon xd?). Does a raw restore to a different memory card allow using these savegames?

 

[OriginalHamster]

It only works for 64mb cards, my bad, wasn't my intention bother tueidj =P

 

[tueidj]

Need more working memory cards dumps (any size smaller than 16MB) for testing...

You mean just the results or do you want the actual dumps send to you?

I'm pretty sure he wants the actual dumps, so he can work out the exact structure etc., so that he can add support to Devolution for dumps of different sizes (meaning users wouldn't have to dump a raw image of their card, and then use Dolphin to move all the saves from it to a 16MB memory card image, but would just be able to dump the image of their card and use it straight off)

It dont work, I tried.
Edit: How is it even possible to block modchip?

It may depends on what modchip you have.

It works fine for my official 1019 card even though it is on its way out because the Wii fried it. We can't test any official card dumps with Devolution because the biggest official card is 8MB. However, Dolphin's memory card manager was able to open and see the save files on the dump.

Have you tried using that 1019 card exclusively with an actual Gamecube? That should help tell whether there's actual damage rather than mere data loss.

Unfortunately, my Gamecube's disk drive is dead, so it's not much use. About 6 months ago a GC game declared the memory card corrupt and said I had to format it, so I did and lost a lot of saves. I thought it would be ok after that, but corrupt save files keep appearing though nothing has declared the card corrupt since then.

If the modchip changes what is reported to the wii in anyway (region patches etc.), it won't be the exact same as a 1:1 rip, and so will not verify.

I created a blank memory card through Dolphin, and import all my .cgi files, creating a 16mb .raw
Strange enough with Devo my games still say that the memory card is corrupted, in Dolphin the saves works just fine...

@[member='tueidj'], here's the dump I got with ctr-gcs 0.2 (251 memory card): http://www.mediafire.com/?6ucy8lrc89yc9tx
