Tales of Symphonia is my new point of reference. r912 seems to have gotten a slight bump in audio performance. ToS still has the music breaking up halfway into the opening FMV, but those video frames seem smoother.

Enable "Emulate Read Speed" for Tales of Symphonia's default configuration entry.

Maybe this helps.

Tales of Symphonia's video may be smoother, but the audio seems to be regressing with 922 and 927; it's noticeably choppier.

Extrems · Nov 4, 2020

There were no changes that could cause that.

R0B0T0 · Nov 14, 2020

New SWISS update with preliminary Memory Card emulation.

An SD Card Adapter is listed as one of the requirements; anyone know if this includes SD2SP2? Or is it limited to SDGecko type devices? I'm interested in trying this out in conjunction with GCLoader.

Alexander1970 · Nov 14, 2020

Swiss v0.5r963

Extrems released this yesterday · 1 commit to master since this release

It's memory card emulation.

It's not quite ready for prime time still, but it has been a while, and general improvements have been pilling up.

It's currently limited to the following device combinations:

DVD + SD Card Adapter
GC Loader + SD Card Adapter

It currently has the following issues:

These devices still use synchronous I/O functions for the SD Card Adapter. Audiovisual glitches may occur during Memory Card access.
Changing channel on, or hotplugging a Wireless Receiver will cause the system to crash upon transmission from a WaveBird Controller on the set channel.
Due to insufficient memory space, disc read speed emulation is disabled.
On a system where a Memory Card hasn't been inserted in a particular Memory Slot since the system settings were last reset, the emulated Memory Card will be reported as unusable.
Probably more. Use this feature at your own risk.

You may already have found out that the answer is currently no to both, but in either case it's a simple mechanical adapter and adding support for the bottom slot is trivial (if only a large amount of GC homebrew wasn't abandoned and/or closed source...)

ALCAMJI · Nov 19, 2020

Im using an SD Gecko and memory card emulation works great with V-Rally 3 (game exclusive of Japan and PAL), but im unable to find the savegame or the virtual memory card where the game is saving. Where is it?

Swiss v0.5r990

Extrems released this 2 days ago

A reload stub enabling homebrew applications to return to Swiss has been added.
While this depend on a libOGC patch that may never make it upstream due to a rift with @devkitPro, the stub offer backwards compatibility with the older standard set by PSO/SDload. As such, many popular applications are supported today.

This feature require a copy of DOL/swiss_r990-compressed.dol on an SD card under one of the following file paths:

/autoexec.dol
/boot.dol
/boot2.dol
/igr.dol
/ipl.dol

Issues with SD cards being unreliably detected, particularly after in-game reset, should now be fixed.
Note: The builds released within the first 12 hours had a new issue impacting SanDisk SD cards.

Fastboot has been removed from ISO/*. GC Loader users may use these instead of GCLoader/boot.iso to see the boot animation before booting Swiss, rather than only before booting games (with boot through IPL enabled).

Fastboot may also be cancelled by holding the A Button so that the GameCube Main Menu can be accessed on power on.

You're right. I think it's a nocebo effect. The older versions had more uniform audio breaks. The recent revisions play additional audio, making it sound more broken.

What can I do?

Hello.

There are different Versions (older) around,but I am pretty sure
for an unmodded GameCube you need the Version from your Region:

I am not sure,but I think for the Japanes GameCube you can use the PAL/European Verson ?

But please,wait for an Confirmation from other Users too.

Marginal audio improvement for the SD2SP2/MC adapter. Possibly less video slowdown; could be a placebo effect.
