games-emulation/ppsspp-libretro needs to install assets directory. #106

crocket · 2018-03-25T02:08:19Z

The details are on libretro-mirrors/ppsspp#65

I think it makes sense to copy assets directory into /usr/share/ppsspp-libretro and tell users to copy it as /path/to/RetroArch-system-directory/PPSSPP

http://docs.libretro.com/library/ppsspp/#bios contains instructions.

Because some users might miss installation message, it will make sense to find a way to tell users about it in other places.

stefan-gr · 2018-03-25T17:16:09Z

That's what games-emulation/psp-assets does. I can't do much else apart from using ewarn to notify users of this.

crocket · 2018-03-25T22:53:45Z

You're right. However, I think psp-assets should be assimilated into ppsspp-libretro because ppsspp and assets are one bundle. Version difference between ppsspp and psp-assets can cause problems.

Another disadvantage of psp-assets is that I didn't know psp-assets were for ppsspp-libretro when it warned me to copy PPSSPP folder into system directory.

Also, I think it should warn users on every install because I didn't know what system_directory was on first install.

stefan-gr · 2018-03-26T09:07:58Z

There are two psp libretro implementations, that's why I opted to use a separate ebuild because they use the same assets folder. They are psp1-libretro and ppsspp-libretro.The former seems to be abandoned nowadays so I don't mind dropping it altogether and merging psp-assets into ppsspp-libretro.

Version difference between ppsspp and psp-assets can cause problems.

ppsspp seems to be kind of special in that they don't care about XDG spec so we have the situation that the PPSSPP directory is also used for savegames and probably other transient files that we have no control over, making version control a pain in the behind.

The best we could do is symlinking every single file manually instead of copying the folder to make sure at least some files are up-to-date without the user having to manually copying them again and again.

…libretro, #106

stefan-gr · 2018-03-26T10:22:49Z

I just did this blind, as usual. I hope everything still works after this.
psp-assets and psp1-libretro are now keyworded to force people to unmerge them before proceeding to update ppsspp-libretro.
The instructions for assets are now printed every time ppsspp-libretro gets merged. This time they are symlinked to make sure they are always up-to-date.

I did NOT test if ppsspp works with read-only symlinks.
Also, the built-in asset downloader will probably not work with symlinks.

Sorry, I forgot that portage needs working ebuilds to remove them.

crocket · 2018-03-26T12:46:34Z

emerge --depclean didn't work, but emerge --unmerge psp-assets worked without synchronizing with your overlay.

The workarounds are fragile. It's better to fix issues that require the workarounds.

crocket · 2018-03-26T13:01:27Z

I think ppsspp-libretro's instruction is outdated. ppsspp-libretro saves games in PSP folder in the folder that contains game ISO files. Thus, the folder structure looks like

/path/to/psp-games/PSP/
/path/to/psp-games/game1.iso
/path/to/psp-games/game2.iso

The command for making the symlink should be

ln -s /usr/share/libretro/PPSSPP /path/to/RetroArch-system-directory/

That wouldn't happen in the first place if I had a machine capable of testing this.

I added a blocker that should help portage in deciding to uninstall psp-assets itself. Just remember to always run emerge -uDN world before a depclean.

I think ppsspp-libretro's instruction is outdated. ppsspp-libretro saves games in PSP folder in the folder that contains game ISO files.

Good to hear. I adjusted the message accordingly.

If you moved the location of PPSSPP in ppsspp-libretro, there would be no collision with psp-assets.

stefan-gr · 2018-03-27T11:56:38Z

If you moved the location of PPSSPP in ppsspp-libretro, there would be no collision with psp-assets.

People that previously symlinked the assets themselves would have a not working installation. At the current state, if my changes are correct, users that just do a emerge -uDN world would not notice the change since everything should be taken care of by portage, provided that games-emulation/psp-assets is not in the world file.
