Please before reading my comment and replying, be aware that I'm very new to 6502 assembly so maybe I won't understand much technical stuff. I'm sorry if my english is bad.
I found a demo ROM at zophar.net displaying the TMNT logo while playing a high quality sample file (probably OGG Vorbis) also known as the show's music theme. They described that it uses an "obscure mapper", probably made from scratch.
I'm very interested into this topic so I might ask you: Is it possible to create a non-physical mapper (for the beginning) that can play OGG Vorbis or WAVE files, during the executing program, without slowdowns?
