ok, well I'm on a business trip and forgot my cellphone cable to transfer videos from my phone to my pc. So no Chip8 on Zune HD in action just yet.
However here's the source...
Recoding the emulator was much faster than I thought. 15-30 mins and I was done. Needed a few bug fixes here and there but thats it. Most of my time was on handling the "Touch Menu" and getting familiar on how I could use the TouchCollection. Scrolling of the list of game took me a while to get working, since I rotated the screen 90 degrees I kept inverting X and Y.
What I really want to do next is rewrite my Menu to look and behave exactly like the Zune menu. Then I'll add input support to the emu and I'll be done.
