Thank you for the great response. I'm glad to hear that compatibility is so high. Since it sounds like everything will come together soon, I'll hold off on my order to get both at the same time. I'm really looking forward to getting them. Thank you for creating these. I have one last question; with there being multiple versions of your HOKEY chip available, which of the versions will be compatible with the Concerto Cart? Thanks again.

Hello. I think I will be purchasing a Concerto Cart in the near future and I have some questions regarding it. I apologize if this is the wrong thread to ask in, or if these questions have been answered elsewhere. I understand that the firmware is a work in progress. How is the current compatibility for original retail 7800 games? Is it around 50%, 70%, or 90+%? What are the current known issues if any? How is the compatibility for demos and homebrew available to load onto the cartridge? Lastly, I would like to purchase the cartridge with POKEY audio in mind. I have a copy of Ballblazer, but I would prefer not to damage it for it's audio chip. Ideally, I would like to order the cartridge with the HOKEY chip as one shipment to cut down shipping costs, as I have seen that it will have advantages over the older POKEY chip. Is there any chance to either pre-order the cartridge with the HOKEY chip and have that shipped out once the firmware is ready, or is there any way to purchase both now with the clear understanding that the Concerto is not yet comparable with the HOKEY? Thanks for your time!

Great! Acording to another AA post (http://atariage.com/forums/topic/74388-7800-voltage-regulator/) the 7800 uses the TI UA7805C. Acording to it's spec sheet it has a maximum Vin rating of 25V. So it looks like I should be fine. Thanks for the help!

How many volts are too many to feed the 7800? I've wanted a 7800 for quite some time. I was lucky enough to be able to pick one up on a recent road trip. When I got home I tested the 7800's stock power supply and found that it was feeding the 7800 13.4V instead of the recommended 9V. Is this too high for the 7800, or is it just fine? Thanks for your time!
