/* gamecache.h - persistent title id -> {name, cover URL} store.
|
|
*
|
|
* Replaces the two caches this used to have:
|
|
* - config.json's "titles" map (id -> name), written by cfg_learn()
|
|
* - artwork_cache.json (url -> mp: path), the art disk cache
|
|
*
|
|
* One file, one job: remember what a title id resolved to, so a boot with no
|
|
* network still shows the right name and the right cover. Name AND art live
|
|
* here because art was never persisted anywhere -- s_last_art is RAM-only and
|
|
* is cleared on every title change, so cover art was re-fetched every session.
|
|
*
|
|
* Pure parsing/serialisation is separated from the file I/O so the host tests
|
|
* can drive it without a console, the same split as procwalk.c and bigapp.c.
