Installation:

• Switch: copy appstore.nro to sd:/switch/appstore/appstore.nro, and run via hbmenu
• Wii U: copy appstore.rpx to sd:/wiiu/apps/appstore/appstore.rpx, and run via HBL
• OR: extract the right *-extracttosd.zip for your platform to the root of the SD card

Changelog:

Switch:

• new theme category + allow theme installation
• NRO launching after installation
• uses GPU to render (smoother)

Both:

• faster downloads
• can actually exit with minus button
• misc category added

Wii U:

• synced with switch codebase! Now using SDL2
• can search now!
• can control without touch screen
• can scroll and read more details about packages (size, changelog, etc)
• can install files anywhere on SD (Retroarch, haxchi, etc updated)
• sort apps, smoother scrolling, and other quality of life things from syncing with Switch

The PC build has also started migrating to Buck + Buckaroo for building and dependency management. It is my long term goal to use the same Buck configuration to compile across all platforms!
