nmk/ddealer.cpp: replace MCU simulation in ddealer with emulated NMK-110 MCU (also tdragon1, hachamf, hachamfa in nmk16.cpp) [Sergio Galiano, Recreativos Piscis, David Haywood, hammy] (#11584)

Browse Source 
* replace MCU simulation in ddealer with emulated NMK-110 MCU [Sergio Galiano, Recreativos Piscis, David Haywood, hammy]
* hooked up MCU for tdragon1 too
* added the nmk-113 dump to hachamf and hachamfa, this appears to be a multipurpose MCU, as it has multiple program paths depending on a port.
* one of the config options in the 113 MCU is for Thunder Dragon, even if we use the 110
* 113 can also be used with Double Dealer in a specific config
* flip ddealer.cpp to more permissive license, with agreement from copyright holders
* load the 215 binary too, even if for emulation purposes it seems unimportant

Appears to be a down-grade of the nmk16 HW
TODO:
- Fix MCU simulation for credit subtractions & add coinage settings (currently set to free play for convenience);
- Understand better the video emulation and convert it to tilemaps;
- 2 players mode gameplay is way too slow (protection related?)
- Decap + emulate MCU, required if the random number generation is going to be accurate;
- Check audio IRQ freuqency (controls music tempo, if too high 2 Player mode becomes slow)

Few words about protection:
- Work RAM at $fe000 - $fffff is shared with MCU . Maybe whole $f0000-$fffff is shared ...
- After boot, game writes random-looking data to work RAM:
00052C: 33FC 1234 000F E086 move.w #$1234, $fe086.l
000534: 33FC 5678 000F E164 move.w #$5678, $fe164.l
00053C: 33FC 9CA3 000F E62E move.w #$9ca3, $fe62e.l
000544: 33FC ABA2 000F E734 move.w #$aba2, $fe734.l
00054C: 33FC B891 000F E828 move.w #$b891, $fe828.l
000554: 33FC C760 000F E950 move.w #$c760, $fe950.l
00055C: 33FC D45F 000F EA7C move.w #$d45f, $fea7c.l
000564: 33FC E32E 000F ED4A move.w #$e32e, $fed4a.l
Some (or maybe all ?) of above enables random generator at $fe010 - $fe017
- There's also MCU response (write/read/test) test just after these writes.
(probably data used in the check depends on above writes). It's similar to
jalmah.cpp tests, but num of responses is different, and shared ram is
used to communicate with MCU
- After last check (or maybe during tests ... no idea)
MCU writes $4ef900000604 (jmp $604) to $fe000 and game jumps to this address.
- code at $604 writes $20.w to $fe018 and $1.w to $fe01e.
As result shared ram $fe000 - $fe007 is cleared.
Also many, many other reads/writes from/to shared mem.
Few checks every interrupt:
