Ah smf, I'm happy to have caught your attention 
I recently discovered the uploaded (I)DCT cosine table as well, and even just added it to my PSX video format document. I've also been keenly aware of the Cb/Cr swap error thanks to your post about it.
Comparing the various decoders out there (I'll be adding MAME to the list soon), it seems there's only a handful that get it right.
I've been trying to add a 'PSX exact quality' option to my jPSXdec video decoder. Since I only have a PSone and the CD based Gameshark, I don't have easy access to PSX ram, otherwise I'd be dumping it and comparing. MAME's output is the closest thing I have to work with, so I was hoping that careful comparison might have already been done. As it hasn't, I would totally be digging into it right now--if only I had hardware RAM/VRAM dumps of the 24 BPP Tekken 3 or FF9 opening movies.
