刘皓	eb8794874e	Don't reallocate memory in wasm_rt_replace_memory unless the memory capacity has changed	2025-07-06 13:38:20 -04:00
刘皓	fd822ea498	Don't seed the Ruby PRNG with the system time in libretro builds ... This allows libretro save states to actually behave the same every time you load them with respect to when randomly generated events occur and the random movements that NPCs make.	2025-07-06 12:27:46 -04:00
刘皓	42d49f7296	Remove caching of libretro stage 1 from the autobuild ... It doesn't take nearly as long for stage 1 of the libretro build process to build as it did when I first started working on libretro builds. At this point, I find it unnecessary to keep caching the stage 1 build artifacts.	2025-07-06 12:06:00 -04:00

刘皓	6806c56a07	Fix a mistake in the previous commit	2025-07-03 13:18:21 -04:00
刘皓	7fa8b8ef16	Fix libretro save states created in the same frame one was loaded being corrupted	2025-07-03 12:39:29 -04:00
刘皓	d1a6d53892	Enforce deterministic iteration order for sandbox fibers ... I've changed the sandbox fibers in libretro builds to be stored in a linked list, with an unordered map mapping fiber keys to linked list nodes for efficient lookup. The original implementation was just having all the fibers in an unordered map. The new implementation has the benefit that fibers are always iterated in the same order on every platform, which allows save state creation to be more deterministic.	2025-07-03 09:16:55 -04:00
刘皓	a2244c25cd	Make sure p->deserYChanged is initialized in Sprite::sandbox_deserialize_begin()	2025-07-02 21:03:04 -04:00
刘皓	81cb43ef37	Prevent unaligned memory accesses in libretro builds ... These are undefined behaviour. All memory accesses need to be aligned. For unaligned memory accesses, we have to use memcpy.	2025-07-02 20:46:54 -04:00
刘皓	e3146c5e1d	Authenticate to the GitHub API in the autobuild to reduce flakiness	2025-07-02 19:24:09 -04:00

刘皓	fd529af870	Don't allow using libretro save states while shared state is uninitialized	2025-07-02 15:20:41 -04:00
刘皓	29c0621771	Call Font::initDefaultDynAttribs() before initializing shared state in libretro builds	2025-07-02 14:38:09 -04:00
刘皓	00c688309b	Fix edge case in pointer unswizzling algorithm for libretro save state serialization ... If there are two Ruby objects, A and B, that are both no longer used (i.e. they're able to be freed by the Ruby garbage collector), and A references B, then it's possible for the Ruby garbage collector to free B but not also free A in the same garbage collection cycle. The pointer unswizzling algorithm currently crashes when the garbage collector does this because the object A will still be in `sb()->objects` but B will not be, and so save state serialization will still try to serialize A. When the pointer unswizzling algorithm tries to serialize all the other objects A references and cannot find the referenced object B, the program crashes.	2025-07-02 13:32:06 -04:00

刘皓	e9450952f6	Fix bug in libretro save state serialization/deserialization of frozen pixels	2025-06-23 20:57:44 -04:00
刘皓	077b461480	Improve code for refreshing OpenGL state in libretro builds ... Instead of resetting all the OpenGL state to the default values on refresh, the code now reapplies the state currently stored in `glState` on refresh.	2025-06-23 20:10:08 -04:00
刘皓	c97b4b8b6e	Don't vertically flip the screen in libretro builds ... Libretro provides the option to make the libretro frontend vertically flip the video output when using OpenGL, so let's just allow the frontend to do that instead of doing it manually. It might be more efficient.	2025-06-23 18:34:35 -04:00
