Toolchain setup

• It's recommended to use vdpm to set up the toolchain: https://github.com/vitasdk/vdpm. In addition to setting up the toolchain, vdpm allows you to install dependencies such as libpng/libjpeg/vita2dlib/etc without any hassle. -- note that at the moment toolchain downloaded via vdpm will be horribly outdated, so this is no longer recommended
• Prebuilt toolchain binaries (Windows, Linux, OSX): https://github.com/vitasdk/autobuilds/releases
• Another option is to build the toolchain from source, check out https://github.com/vitasdk/buildscripts

Build process

xyzz

Use latest prebuilt toolchain: https://goo.gl/QpX5zM (the one at the top)

New build step has been added, after vita-elf-create you need to run: vita-make-fself homebrew.velf eboot.bin You need to run vita-make-fself on the .velf, not .elf The resulting eboot.bin can then be put into a .vpk archive, read below

Homebrew installer uses a .vpk format which is just a ZIP file, start from this template: https://github.com/xyzz/Vita_Doom/releases/download/1.0/vitadoom.vpk (try installing it from the shell)

• replace eboot.bin with your eboot.bin
• you can also add template.xml and stuff like icon/background/etc that will be displayed in livearea, check out how it's done in molecular shell (launch it and go to app0)
• make sure to run pngquant on all your png images https://pngquant.org/
• to make param.sfo, use vita-mksfoex -s TITLE_ID=XXXX00001 "homebrew name" output/param.sfo
