Need someone with a known working 100% DECO cassette system

We need to do some tests on the older and larger pcb set. Our project is already confirmed working on the smaller sets and it should work on the larger sets but either my large pcbs are non working or our kit isn't.

Let me know if you can help with testing.
 
I have 4 decos. cocktail, 2 different types of dedicated uprights, and kit deco into a tempest cab. None have working cassette (won't load), but I have a widel kit for one of them. If you need some testing let, me know and I will try to help.
 
Why can't we just FPGA the entire Deco system and get a zillion games in one shot?
 
FPGA emulation is for poseurs :D (sorry JROK)

Actually, FPGA isn't emulation, it's more like a clone of the original hardware. For example, my major havoc FPGA uses a Verilog 6502 that runs at exactly the same speed as the original hardware. Mame emulation simulates the processor speed so it will never "feel" right. FPGAs should be able to match the original hardware "bit exactly" down to the last cycle. The guy working on an FPGA pole position built a board to compare, in real time, his FPGA recreation of one of the custom asics to ensure that the FPGA version was exactly the same. I've had a guru level tempest player (e.g. level 99) play my FPGA version of tempest and he could not tell the difference. FPGA should be able to implement a game with indistinguishable "feel" to the original game for expert players that are very familiar with the game.
 
Personally I'd love to see a full FPGA for the DECO system, the boards are tough to come by and a LOT of cabs have been converted to the point there are few left intact, it would be nice to see some of them be able to be converted back. Also there's a huge selection of games available once a multi-cassette replacement is made, some of them are quite good and only available for the DECO system.

Should being the key word. It's all up to who implements it.

I agree though that FPGAs shouldn't be lumped in with emulation. I don't quite agree with clone though. I prefer simulation.

I always just called them replacement boards. They run the same software and get the same results when running it.

Do pinball guys get all uppetty if the design of replacement boards differ from the original?

Your statement isn't true though. FPGA doesn't mean you get the same results. It could run really bad. It's all up to how it is implemented by the designer.

You are spoiled by what JROK has done which shows how both simulation and emulation can be used and provide the same exact results.

Other projects have come to market and the designers didn't have the same results. Other projects take a while because the designers are making sure they provide the same results. Eventually though there will be an FPGA board that is released that doesn't provide the same results, maybe better, maybe worse.


As for the pinball, I'd assume it's same as arcade. Some want something cheap while others are actually looking for the same exact results.
