Konami Picno and Picno2

Skeleton driver started on 2017-11-30, can be claimed by anyone interested.

Information provided by Team Europe.

Chips: HD6435328F10 (H8/532 CPU with inbuilt ROM), HN62334BP (27c040 ROM), Konami custom chip 054715 (rectangular 100 pins),
       HM538121JP-10, M514256B-70J, OKI M6585.
Crystals: D200L2 (Y1) and D214A3 (Y2), frequencies unknown.

The hardware of the Picno 1 and Picno 2 is completely the same. The Picno 1 has an Audio-Line-Out, which the Picno 2 does not have.

Maskrom of PICNO 1: RX001-Z8-V3J
Maskrom of PICNO 2: RX001-Z8-V4J

The size of the address space and other things is controlled by the 3 mode pins. It's assumed we are in Mode 4.

Can't do anything until the internal ROM is dumped.
