Re: Sounds Like Plaion Has Another Console In The Works Following The Neo Geo AES+

@Razieluigi the thing is: if it's exactly like the original chip, there's no "problems" to arise. And the Neogeo used the 68000 and Z80, two of the most popular and produced chips of all time.
It's a rather safe bet that there won't be any issues.

The concept of a chip needing "updating" when it comes to an FPGA, is down to the fact that the FPGA is essentially simulating the original chip's logic using a much more powerful processor. Similar in concept to how software emulation works, but on hardware. So some small bugs can show up.

Your concern is valid, they could mess up the ASIC, even if unlikely. But even if there are some very specific little bugs, they could just release a newer revision of the hardware later. This is how things were back in the day too. Consoles had internal revisions all the time (see MegaDrive sound chips fluctuating in quality over time).
