I've been adding in the new Pokemon cries. It took longer than expected because I had to rearrange the entire audio system, but it works.
For Gen 2 Pokemon, I just copied the cries directly from Crystal since the audio system is close enough. I still have to fine tune them since the audio engines aren't identical.
I also imported the pokemon yellow routine which plays raw pcm audio (thanks to shantytown), for the cries that I couldn't rip from Gen 2. Those aren't perfect, since its 1 bit audio, but it's the easiest way to play those cries.
Also, I've spent a lot of time on my side project website which I would like to announce soon.
I hope to finish the cries and energy next week while I am on vacation
