+// This file is here for temporary decomp notes about SpriteOAM. It can be deleted later when we figure it out.
+// SpriteOAM initialization is handled by inlines. Potentially has inlines for other scenarios [for example: AddSprite()]
+
+// There is lots of testing done and evidence that it most likely is not handled by macros.
+// Some funcs (such as sub_8039174) can be fakematched with "{} while(0);" contexts and a temp var. Note that it's not a "do {} while(0)" but just a "{} while(0)".
+// However, that does not work for most funcs, and does not produce some of the register preloading we get with inlines.
+// Also, the inlines I (kermalis) have tested with DO produce the behavior we see in all of the funcs. It just doesn't match 100% yet.
+
+// Most of the special work seems to be done on the first two u16 of SpriteOAM.
+// They are usually loaded/stored separately from the second half of the struct.
+// There doesn't seem to be a logical reason for SpriteOAM to be split into two substructs, but the evidence points to it.
+// AddSprite() still hasn't been matched (I'm writing this Dec 4 2024), because it suggests SpriteOAM is actually two separate substructs.
+// "volatile u32/u16" was the first thing we tried, but it produces horrible asm and doesn't make sense for Chunsoft to have used it in this context.
+// The main breakthrough came from producing 99% similar asm through attrib1/attrib2 being a substruct.
+
+// Proposed struct definition:
+typedef struct SpriteOAM2_Sub1

+    SpriteOAM2_Sub1 unk0;
+    SpriteOAM2_Sub2 unk2;
+} SpriteOAM2;
+// (It's called SpriteOAM2 temporarily to avoid conflicts with the current one)
+
+// There seem to be 3 ways of handling SpriteOAM that I have found so far.
+// #1 - When a SpriteOAM is initialized on the stack, certain inlines set its fields. This produces heavily inefficient asm but that's what they did.
+// #2 - When a SpriteOAM is initialized from ram, it uses different inlines that produce way better asm. They're still known to be inlines because of the register preloading.
+// #3 - Sometimes neither of the above 2's inlines are used for attrib1. It appears to be a third set of inlines (didn't attempt yet, feel free to).
+
+// For type #3, way more testing needs to be done.
+// The thing is, in all 3 scenarios, an identical order of operations is usually applied.
+// The asm being nearly identical each time also makes it unlikely to be done manually without some macros or inlines.
+// And this is why we haven't "real" matched many (any?) SpriteOAM funcs in the years this decomp has existed.
+
+// Here are some helpful decomp.me links with examples.
