Gecko dotNET Bugs and Requests

[dcx2]

Yes, Riivolution supports the USB Gecko.

http://rvlution.net/wiki/Ocarina_Codes

Riivolution also supports wifi redirection.  So you can keep the code handler binary on your computer, so you can easily swap in new code handlers.  But you would have to restart (EDIT: restart Riivolution not the PC), because Riivolution copies the codehandler.bin file into memory when the game is loaded.  About as brain-dead simple as it gets in terms of upgrading your code handler, but that's if you get Riivolution working, and it doesn't support channel cheats or GC games.

Hence why I lean more toward using gameconfig pokes, because it's widely supported due to Brawl+.

@dcx2:
there are still some issues with monster hunter and gecko.net!
If I set a breakpoint, before the game goes into a black screen loading thing, windows says that "gecko.net doesn´t work anymore"
And on Breakpoints tab it writes "invalid address" where the instructions are supposed to be put.
Therefore, gecko.net closes itself. If I open it up to connect again and switch to memory viewer, it freezes the game for at least 15 seconds and continues after a while. Setting an execute breakpoint recovers.
However, the freezing issue through auto-update is fixed ;D

(gecko.net version 0.66.7.)

EDIT:

damn, it´s fixed in 0.66.8. cool O0

For Project M too?

[Bully@Wiiplaza]

yes, it also improved the ability to catch breakpoints. 8)
Great, I just made a crash fix code that wasn´t possible before. :p
No problems so far.

[Stuff]

Without permanently modifying a dump, I would like for the disassemble tab to work with dumps So I can jump to an instruction's address and see the asm there. With assemble working like usual, just not modifying the dump.

Also, in addition to the gct code option in the context menu, I want it to do a 'copy code'. So instead of having to go to the gct tab an make a new code, I can just have it in my clipboard for pasting everywhere.

[Bully@Wiiplaza]

switching to memory viewer while gecko.net is doing a ram dump disconnects gecko.net and freezes the game.
No BP or reconnect is possible.

[dcx2]

@Stuff

You're the second person to ask for dumps to be read-only.  Believe it or not, I actually assemble dumps on purpose all the time.  I have yet to find a really good way to calculate branch offsets for codes from dumps.  Pasting the branch into a dump is pretty much the best solution I can think of because the branch displacement operand will depend upon the address being assembled.

I'm not really sure what you're asking though.  You can already load other dumps into disasm and jump to ASM.

So, instead of making a new code on the GCT tab you want the code put into the clipboard?  That should be easy enough.  The context menu is getting pretty long though...

---

@Bully Doing *anything* while dumping will crash the game.  That's why it disables all the buttons while it's dumping.  Were you doing a Tools tab dump?  Because search should lock you to that tab...

[Bully@Wiiplaza]

yes, as I said, it was a "RAM dump" (therefore: tools tab)
you may want to fix the freezing OR disable tab switching.

[dcx2]

Technically, search tab can dump, pointer tab can dump, tools tab can dump.  I guess I should verify all those are tab-locked while dumping, because there's no way to fix that freeze.

[Bully@Wiiplaza]

It was pointer tab, but same thing I guess...

[Stuff]

disassemble tab: Oh I didn't see the source dropdown in that tab XD. nvm then. Well. Guess I could make a backup dump then. :/

context menu: I guess if size is an issue, you could put the gct related stuff in a sub menu. :/ Don't really want that, though. And it's only one more option. Give it a kb shortcut if it has to go in a sub menu. I think it would be one of the more used options. The gct tab could use a button for that too. Right next to Store Immediately, Copy to Clipboard. This one would copy the current code with the name as well. I'd say one for the gct wizard, but I've never used that. :p How come add to gct is only available in the disassemble tab?(I don't use that either. Just wanna know. It's not all that serious.)

[dcx2]

Yeah, I make backups of the original dumps before I do any working on them.

If size starts to become an issue, I'll try to use lesser-moved functions like the F2 XOR, SRR0 stuff to a sub-menu.

Store Immediately is kinda obsolete now that GCT's autosave.  Heh.

I created Add to GCT because when I was making a long list of 04 ASM patches, I got tired of copying and pasting from "New Code"'s into the code I was adding to.  Some codes are just a dozen or so 04 ASM patches.  So I made the Add to GCT, and I populate the dropdown with the reverse list of the GCT codes so the most recent code (which is usually at the bottom of the GCT list) is what pops up first.  It's not anywhere else because...well...99% of my hacks are ASM so I end up using either disasm GCT or PyiiASMH/ASMWiiRD.

[Bully@Wiiplaza]

errgh.. >.<
gecko.net 0.66.8 still freezes on some C2 codes... (tried on 1931)
" Wii Exception caught, switch to BP tab"

The destination/source register is always 00000001 (or 00000000) when that happened (I noticed...)
I used an old built (r93) and sending the same code didn´t crash. It just worked :eek:
There´s definetely something wrong with the checkexisend command... :(

What game?  What loader/code handler? (look at Tools tab to identify handler)  What C2 code?

There's something fishy about that ASM.  Look at the pattern.  I'm going to insert line breaks so that the pattern becomes obvious.

This stands out to me because it's the "right" way to push/pop the float registers on the Wii.  The Wii supports Paired Singles (ps*) instructions, which operate on two single-precision floats in one float register.  The float regs are actually 64-bits, but the code handler only displays the first 32-bits.  It is an error to load a double (= 64-bit float) and then store as a Paired Singles (= two 32-bit floats).  Therefore, to ensure there are no errors, float regs are pushed and popped as both doubles and paired singles.

Something is over-writing your ASM.  Check 8074F674 without any codes activated and I bet you'll see psq_st f29,232(r1),0,0

EDIT3:

Another fishy thing to look for.  Where did r29 come from?  Arguments are passed in using r3-r10.  Arguments are never passed in using r14-r31.  Nothing in the beginning of the function has loaded r29.  A compiler following the EABI would never do this.

EDIT4:

Look at the function epilogue, which pops the float regs off the stack.  Notice the symmetry with the function prologue.

EDIT:

You should avoid speculating about what happens in the code handler unless you have studied it.  This crash is nowhere near checkexisend, which exists way down in 80002XXX range.

EDIT2:

Check for GCT Code Undo which is poking something it shouldn't be.

8074F674:  909D0040   stw   r4,64(r29)   # ????  Should be psq_st f29,232(r1),0,0

Something is over-writing your ASM.  Check 8074F674 without any codes activated and I bet you'll see psq_st f29,232(r1),0,0

you´re right, it´s a psq_st on disassembly (when game is running) but it froze on that stw that popped up on breakpoints tab.
I sent a C2 code to hook the button address on main screen.
It´s handler 1931. Weird thing is that it doesn´t freeze anymore when the ASM has changed due to selecting a different spot in-game (8074F674 has different instructions now) Even though, the actual code is hooking "base" assembly. Undo was correct.
