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.

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.

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. Resolved in v0.5r1047
• Changing channel on, or hotplugging a Wireless Receiver will cause the system to crash upon transmission from a WaveBird Controller on the set channel. Resolved in v0.5r1026
• 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. Resolved in v0.5r990
• Probably more. Use this feature at your own risk.

It's over nine hundred! Wait, I'm off by an order of magnitude.

The disc read speed emulation for GC Loader has finally been completed. This is known to fix a race condition in Tales of Symphonia preventing progress past Palmacosta. Note that NKit images will have a lower simulated read speed than full images.

You can now set a game to be loaded at startup. This require a configuration device.

NKit images are now checked against an internal database, and the nag has been removed for discs not in Redump.
