* That's why we have to hash the TLUT too for TLUT tex_format dependent textures (ie. GX_TF_C4, GX_TF_C8, GX_TF_C14X2).
|
|
* And since the address and tex data don't change, the key index in the cacheEntry map can't be the address but

|
* have to be a real unique ID.
|
|
* DONE but not satifiying yet -> may break copyEFBToTexture sometimes.

|
|
* Pokemon Colosseum text issue (plain text):
|
|
* Use a GX_TF_I4 512x512 text-flush-texture at a const address.
|
|
* The problem here was just the sparse hash on the texture. This texture is partly overwrited (what is needed only)
|
|
* so lot's of remaning old text. Thin white chars on black bg too.
