Swiss 0.1

[wii_HD]

Using the second test Swiss.

Like Hells Guardian - Read patchable and likely to boot are green - but I get black screen - no logo - no speech - nada.

Tried three times with the same outcome.

[emu_kidid]

ok no problem, we're getting closer at least - I'll have to find my NTSC Luigis mansion and figure it out

Hells Guardian, the problem is that when swiss crashes in a game, it's dead, so would be your debugger.

Hi emu_kidd, my Zelda Wind Waker NTSC on Wii USA is freezing when I press the "up" in d-pad for opening the dungeon map. Any fix for this?

Other players got same bug on brazilian forums

Thanks and congrats again for your work - the game is working perfect, apart from that

[Hells Guardian]

Fair enough. Glad we are getting closer to Luigis mansion working.

[emu_kidid]

rod_br, I will look at this issue, it's near the top of my list

Hells Guardian, the problem is that when swiss crashes in a game, it's dead, so would be your debugger.

I'm not sure if this applies in this case, but generally the Ocarina debugger traps exceptions, so if the game crashes for any reason, the debugger code handler immediately runs and can dump RAM/registers for further analysis. I imagine there's a good likelihood that this would work when a game crashes in Swiss, as long as the debugger has been loaded beforehand.

[emu_kidid]

biolizard89, that's great then, I thought it wasn't catching exceptions

[Hells Guardian]

Thats what I had heard so thats why I'd figured the debugger would be an aid to you. However it's been ages since I'd read on the USB Gecko so I knew I may be wrong. Or possibly one of those rare cases where I was actually right.

Me too. I always thought the exceptions are handled via exception handlers that are located somewhere at 0x80000000-0x80001800.

I wonder if adding a memory dump via usb gecko would work for this? I also wonder if i can take some of the memory from 0x80000000-0x80001800 with the "disadvantage" that if the game crashes, it crashes.

[biolizard89]

Well, I have observed that when a game crashes and I have Ocarina enabled, I'm able to look at registers and RAM via USB Gecko. More skilled hackers than I report that they are even able to modify registers via USB Gecko and cause the game to uncrash. I assume this is done by trapping exceptions, although that's just my assumption. (Is there any other way that could work? I know the USB Gecko can't trigger exceptions, so clearly the code handler runs while the game is crashed....)

[emu_kidid]

problem is when things crash it's crashed in my EXI code and the bus is left a mess.. still, the usbgecko might be ok to communicate

[panmusic]

Emu_kidid,any news from the development front?Any progress about Luigi's Mansion freezing,video compatibility etc. ?
It is awfully quite the last few days...

[emu_kidid]

It's been non stop easter/family stuff for the last week for me.. I've been looking at Luigis Mansion NTSC too, nothing yet. I need to do a major overhaul on the front-end to get a proper file browser happening too which is underway.

[panmusic]

That's nice to hear!
Happy Easter!!!

[infact]

I need to do a major overhaul on the front-end to get a proper file browser happening too which is underway.

So libwiigui is coming?

[emu_kidid]

infact, I haven't decided to be honest.. do you guys prefer it?

[andzlay]

Yes! I don't like the swiss GUI With gx it would be lot easier to modify swiss to a version without GUI or whatever. I tried to understand some of the code but the gui stuff you wrote is confusing me...

[infact]

@andzlay: I dont think it makes any difference, which interface is used for that purpose.
But you are right, the interface emu used until now, adopted gcos stuff, is like 2006 and not bleeding edge.

@emu: Well, libwiigui has pros and cons.
It is serious work at first, but then easy to modify later (do more, write less).
It is in some parts overweight (strip all the wii specific things and the not needed sound effects, etc),
but in other parts it just fits the needs (e.g. great filebrowser).

But when we look at the alternatives (freetypegx, grrlib, ...), it's in some parts the same.

When you intend to use a self created user interface, it can be like reinventing the wheel sometimes. But it will be unique...

But, it's your choice. You have to be happy with whatever you use.

Only thing i can offer is to help you with libwiigui where i can.

[emu_kidid]

I'll give libwiigui a try after I consult with tantric a bit about it

[emu_kidid]

people who have been testing Luigis Mansion NTSC (not players choice), is your dump a verified dump? can I get some MD5's? I've seen one floating around online which is bad - it's possible this is the issue.

[panmusic]

I personnally dumped my PAL copy of Luigi's Mansion.I am not sure of that helps...

[infact]

@panmusic: no, cause it's PAL, the problems are with the NTSC version.

[panmusic]

@panmusic: no, cause it's PAL, the problems are with the NTSC version.

Sorry for that.But no matter what,my PAL Luigi's Mansion is freezing just the NTSC version...

[infact]

No problem, didn't know you have problems with the PAL version.
Have you tried rebuilding the iso with fstfix?
Another Question: What is the checksum for your ISO?

Here is mine:

Code: Select all

FILE: Luigis Mansion PAL.iso
CRC-32: eed631c9
MD4: 31d45203e03ee7977a8745e8d4ade926

Graspingly - According to wiki - Luigis Mansion is the only GC title with stereoscopic 3D support.
