For this release, @cristofercruz has kindly contributed a new interface theme. We hope you'll like it.

A new fastboot apploader has been introduced. Users with an optical drive emulator can now enjoy near-instant access to Swiss. You can use the boot through IPL feature to bring back the boot animation when loading games.

Patching certain late EA titles with non-stripped ELF binaries has been fixed.

The music in Baten Kaitos: Eternal Wings and the Lost Ocean has been fixed for devices using full DI emulation.

To commemorate these changes, we've bumped the version number to 0.5.

Cleaning up the mess from the previous release, the Wiikey Fusion should now work better than ever, including 2-disc support.

A long-standing bug causing crashes with DVD/GCLoader and patch fragments has been fixed.

There's now the option of booting games through the GameCube Main Menu. This feature has some issues still, but it mostly work. Current game settings apply, so it can be seen in progressive scan.

@EBLeifEricson committed:

• Added check of SP2 slot for cheats when on a different device

@Extrems committed:

• Add exception for PAL games booted through IPL.
• Show disc number when other disc has been found.

• Add region patch for BS2.
• Add video patches for BS2.
• Port Wiikey Fusion over to the new patches.
• Add boot through IPL feature.
• Rewrite workaround for CPU lockup on EFB Z peek during a copy operation.

DVD/GCLoader have been ported over to the new read patches, and all games are now treated as potentially reloading. This allow certain games, most famously XIII, to be played in progressive scan using an original/backup disc or GCLoader, and also allow other patches to persist across resets. An SD Card Adapter is required for this to function.

If you had disabled the new read patches before, these will be reset to enabled. The option to disable them has been replaced with a more succinct "Emulate Audio Streaming" option. This should also fix cases where they've been inadvertently disabled by the last release. This option only take hold for SD Card Adapters and IDE-EXI.

@Extrems committed:

• Fix comparison with falsely flagged audio streaming.
• Save and compare disc header.
• Port DVD/GCLoader over to the new patches.
• Hide .nkit.iso extension.
• Hide swiss_patches directory upon creation.
• Implement sync ioctl.
• Check other file attributes of existing patch fragments.
• Change "Alternate Read Patches" option for a "Emulate Audio Streaming" option.
• Simply enable interrupts and call OSResetSystem.
• Hijack current thread to call OSResetSystem.
• Patch EXIDetach.

An issue preventing an SD card on Serial Port 2 to be detected, or making it run at a slower speed, was discovered.

I apologize for the inconvenience.

In this release, I've added a new, more game oriented File Browser type which can be enabled via the General Settings screen. The ability to configure network options within Swiss itself is now possible too (not for SMB yet). Additionally, default game settings should now apply on games that have never had their config saved before too, there'll be some more work in the future regarding being able to default specific options, since the current default is more a "settings template for new games". @Extrems fixed SD initialisation issues with some additional commits in libOGC to back the changes.

@emukidid committed:

• Tidy up last commit
• Fix issue #301, tidy up some unused warnings
• Display bba_ip on info screen if initialized
• Fix GCLoader device name
• New optional file browser targeted at GCM files
• Push WIP text entry for certain settings
• Fix default game settings for new entries

@Extrems committed:

• Adjust for libOGC changes.
• Add auto speed downgrade.
• Make use of EXILock with SD Gecko and IDE-EXI.

For this release, while I mostly focused on the Broadband Adapter, the way in-game reset work in the new read patches has changed. @emukidid worked on improving file browsing speed.

@emukidid committed:

• Make less calls when reading banner data, standardise it with a struct
• Fix banner description display when carriage return is present
• Fix read/size issue when banner is at the end of the file

@Extrems committed:

• Make use of EXILock callback for transmit.
• Make use of __OSMaskInterrupts/__OSUnmaskInterrupts.
• Change IGR to call OSResetSystem in idle thread.
• Fix another cause of missed interrupts.
• Don't trap reset button if not using IGR.
• Find __OSUnhandledException and put it in our table.
• Reuse __OSInitSystemCall to install a jump table.
• Smooth things out with the Broadband Adapter.

It's time to upend compatibility and performance again.

This release fixes certain edge cases that couldn't be seen with the Broadband Adapter (File Service Protocol), where most game testing occurs.

While there may be regressions, there is no turning back.

@emukidid committed:

• Avoid NKit message on WODE entries by setting entry size to DISC_SIZE

@Extrems committed:

• Fix issues with timer 2+.
• Fix FAT disk status.
• Remove signatures that are no longer needed.
• Add signatures found in 007: Everything or Nothing.

• Other minor corrections for GCLoader.
• Refactor read scheduling.
• Do our own scheduling.
• Remove workaround for race hazard in Luigi's Mansion.
• Remove game-specific patch for Viewtiful Joe (Europe).

• Fix regression with Wiikey Fusion.

I guess I'll just release at my own pace now.

This release frees you from arbitrary file naming conventions for 2-disc games.

@emukidid committed:

• Update gcloader.png to final

@Extrems committed:

• Find second disc through the metadata cache.
• Don't load stale patch fragments.
• Fix igr.dol without patch fragments.

No, this doesn't prevent using the SD2SP2.

@emukidid committed:

• Don't patch PAD for GCLoader since it has no patch base installed (yet)
• Don't install execD patch unless if we really need to (non alt patches is the only real use)

This release adjusts the SD card read timeout in-game to match with what libOGC has, it will only apply to SD cards from a memory card slot or SD2SP2. It may improve the situation where a SD card works in Swiss/other homebrew but fails to boot ISO files.

Other minor optimizations have also been made to in-game patches.

@Extrems committed:

• Match libOGC's R1 timeout.
• Minor optimizations.

This release fixes read errors using the alternate reads (issue #244):

@Extrems committed:

• Fix random missed interrupt.
• Fix Game Boy Player Start-up Disc soft reset.
• Update FatFs to R0.14.

This release fixes broken WKF/WASP support.

This release adds support for micro SD cards via Serial Port 2 on GameCube consoles where that port exists. It requires a small PCB (open source design here) and the compatibility/speed is the same as using an SD card via the front memory card ports. The main benefit is that it leaves the 2 front slots free for a memory card and any other peripherals you might require in games.

That being said, the alternate read patches (which are now the default) have basically been rewritten by @Extrems since the last release and should be much more stable and compatible. 2-disc support has been added into these patches but audio streaming is still only available via the old non alternate patches for now.
