ASIC chips are ready. With handy for probing pins.

I visited the idea: I can experience them out of MD environment. I can make testbench for TA-04 and TA-05. TA-06 too complex for this.

Very nice! Is there a reason why you are looking at the clone chips instead of the originals? Do the clone parts have some interesting or undocumented functions?

The reason is simple: I don't have any of it. Beside, as I know the TA chipset most accurate clone to original. For example, this TA-04 was replaced by me more than 15 years ago and it still works (burned out arbiter was the reason to change this superclone to onechip MD2 clone):

Anyway, it is better that system was divided into units and testing that units separately is much easier than whole system. You always can assemble those parts into one unit, right?

HAve you guys heard about retro VGS (http://www.retrovgs.com) ?
It's an ARM Cortex 8 (single core, 1GHz) coupled with a 49k EL FPGA.

We don't need yet another emulator. We want a simulator.

Of course, of course, I know.
I just wanted to drop the specs.
I was thinking about Kaneda line :
... i'll like to know if a FPGA (or a SoC) version of Genny is possible ? ...
In this "Retro VGS", in what I thought was related, the ARM would be idle, while the FPGA would be the actual Genesis.
Not emulated.
Just FPGA-simulated.

Sorry if off-topic.

Some update.

Need to allocate some time to build working DIY prototype.
