I thought the PCB would be the same but different encrypted CPUs would be required? FD1094A, FD1094B for 68k and MC8123 for Z80?
I assumed the games that need the 8751 still won't be playable on V2 either
V1 will cover the wants and needs of 90% or more of customers. I know everyone is spoiled with cps2 and its flexibility. The fact is very few platforms are as clear cut as cps2 ended up being once its security was understood.
A system 16 multi that covers all of the bases of restoring encryption, etc. Just isnt currently possible yet, even with recent developments, and will be quite expensive to include in a single solution should all of the knowledge become available in the future.
So in closing I say "Fuck it". Enjoy all of the games on v1 very soon and worry about all that other shit later.
