Fix TimeSplit crash on empty name Initialize OptionValue::mVal to fix undefined behavior Fix undefined behavior in GraveHoleJumps surface type copy. The memcpy was reading 33 SurfaceTypes regardless of the actual count, causing a buffer overread since NTSC 1.0 only has 31 surface types and later versions have 32. Now uses the actual surfaceTypesCount from the collision header. Fix undefined behavior in framebuffer OTR signature check. Use calloc instead of malloc for framebuffer allocation to zero-initialize the memory. This fixes Valgrind warnings about reading uninitialized values when ResourceMgr_OTRSigCheck reads from framebuffer pointers to check for the "__OTR__" signature. Fix undefined behavior in fontLoadStatus initialization. Use calloc instead of malloc when allocating fontLoadStatus array to ensure zero-initialization. This fixes Valgrind warnings about conditional jumps depending on uninitialized values in AudioLoad_SetFontLoadStatus.
