Hey All,

So after helping work on a faulty Berzerk and playing "which board and what bit is broken next ?!" I was encouraged to look at replacing all the boards, and the wonderful interconnects, with a single solution. So this was born....

It's JAMMA and the idea is that it'll plug into the power and RCR board, replacing everything else.

It isn't just an emulation board using a hack of mame, it's running on a z80 and the FPGA reproduces the rest of the original board hardware. The concept being to match the timing of the original precisely.
That's including the wait states on accessing video RAM & I/O, plus matching interrupt timings. So in real terms it runs like the original.

The Speech processor is all handled by the FPGA and is based on the original published patents and awesome writeup by Jonathan Gervaryahu.

The board in the video is a fully functional prototype, the software and FPGA are complete and it's just up to some testing to make sure I've not missed anything.
If there's enough interest I'd like to do a run of them. Pricing would be right around $175, possibly a little less.

You want to go the extra mile? Include both Slow Bullets and Fast Bullets, and I could test the Frenzy and Slow Bullets for you to tell you how close it is to the real thing if you are interested.
 
..........

..........Me want :)

Any idea when these are to be produced? Edit - how many PRE-ORDERS/PUT ME ON THE LIST to get these started?

Put me on 'The List' for one at any rate....

WooHoo!!

I'm in for one. (just bought an extra set of wico 8ways this morning to be ready).
and I predict the price of the wico 360 optical conversion will go up as a result of this great project. :)

Edit- if you really wanted to take the project over the top, add a setting where you could choose which robot as the top robot in Slow Bullets.
For example, being able to up the difficulty by changing from the light blue robot to the bright yellow, green, pinkish, white robots.

I second Grant/Disjaukifa being a test pilot. He is an exceptionally good Berzerk resource and instructor! :)

I've been really happy with the quality of you rmulti-williams so I would be in for one of these, too.
 
Please add me to the list. I'm in for 1 maybe 2. Freakin awesome!!!
 
Sweet.....

Ok, sounds like slow/fast bullets is a must have then.

I agree on this, too.

I haven't watched your video all the way , yet...but I'm assuming all game versions will have High Score Save & Free Play mode option?

Is there an attract mode available for these, too?

Any chance of the Title screen allow for customized version?

Something like, 'Welcome to the GackAttack Arcade' would be my version :)

Great work!
