PPSSPP 1.17 is now out! Get it on the download page! If you're on Android and already have it installed from Google Play, your update will arrive within a week (to catch crashes early).
For fine details, see the news item.
For the first time, you can now sign up to receive beta versions automatically. This is easier and safer than installing APKs from the buildbot, and you make a valuable contribution to development. See details here.
CHD was originally a format for compressing hard drives from arcade games in MAME, but has since became the most popular format for storing ISOs for CD- and DVD-based video game consoles. PSP already has a different format, CSO, which can be used to similarly loss-lessly compress ISOs, and as a bonus, unlike CHD, these actually work on the real hardware.
So you might ask, why support CHD? It does provide a slightly better compression ratio, but the main reason is that it's simply been requested a lot. Many people seem to familiarize themselves with a set of tools, and since CHD works to compress ISOs for most other systems, people just want to stick with it. So now we support it.
IMPORTANT! You MUST use the createdvd
command from recent versions of chdman
to generate your CHDs. createcd
will work but there will be severe performance problems (EDIT: These have been fixed in 1.18.1). See issue #18798.
Example command line:
chdman createdvd -i "Grand Theft Auto - Vice City Stories.ISO" -o GTA_VCS_dvd.chd
