These all look fantastic!

Yea that's a weird one...of the games you mentioned, I only have Gradius but I don't recall seeing an issue with it. I guess that's a good excuse to go play it some more! When it resets during gameplay, is there a particular point that it happens?

Based on the facts you presented, it sounds like your CV may be the issue... Cartridge port?

I am interested in a HOKEY and a CEM #1.

I’m also waiting on an invite to buy a hokey. I bought my cart a long time ago and more recent buyers have a hokey already…

I’m still patiently waiting for that email as well. Having said that though…given all the issues that Fred is having to track down and issue firmware updates for, does anyone have an opinion on whether the HOKEY or a real POKEY is better to use with Concerto? Any benefit of one over the other?

https://www.ebay.com/itm/124021832058 Found these here, $25 each, but "make an offer" and could get them for less. Could be an option? Cheaper than both DigiKey and Mouser. Not sure how many you would be looking to buy.

This is great news! You'll get quite a few orders from us arcade folks too...

I don’t think mailing it back will be necessary. Installing a Hokey will be as simple as pushing a chip into a socket.

When did HOKEY chips go on sale?

Thought about this project today, and just curious if there are any updates.

I just read this entire post, and I thought the same thing: bad cart connector. Bent pins on the inside of the connector, or even cold solder joints on the connector pins on the bottom of the PCB, or both.

I believe Renato was replying to batari’s post.

That’s correct. As batari has stated in previous replies, there isn't a hardware path to upgrade the memory in pre-production units. I believe he may offer a trade-in program to upgrade to the production version, but please don’t quote me on that.

The POKEY has a socket, you do not need to solder anything. The RAM upgrade is not mandatory if you don't care about support for ROMs up to 1024K. If you choose to upgrade it, you would need to send the cart back to Batari, as three surface mount chips would need to be soldered into place. As far as I know, he is still working on some firmware updates before that upgrade will be ready to go.
