Hmm... may somebody has some idea? velesoft? z00m?.

Hmm... the data itself dynamically allocated of course (the patch does not change this area at all), only the administration area (the memory_page struct) 'multiplicated' in order to each periph have their own.

If more than one peripherale share the ROMCS line than they clash with the "last" because there is only one romcs memory_map (memory_map_romcs[]).
Here is two patch:
- first change the common memory_map_romcs[] to local memory_map_romcs[]s for every peripherials
- the second change memory_map_read[] and memory_map_write[] to pointers.

khmm... khmm... first i want to see a more or less proper boot... and next we start a debate about 2k/128k ROM or 128k/512k RAM ;)
So, now i stuck somewhere in boot loading. After mb02 load the first sector to #8000 (#400 byte), reset DMA, "abort" FDC, stop FDD motor, and "hang up". The Z80 make endless circles around #002b:
#002b CPL
#002c LD (HL), A
#002d XOR (HL)
#002e LD (HL), A
#002f XOR...

Uhum... thanks.
BTW... IMHO... to pull /ROMCS when /RESET is a kind of automapping "point" ... :)

I open a patch item#2858687 for it...
BTW:
"MB02 has no any automapper, any pagging memory
space on #0000-#3FFF is done with explicit OUT by software."
This is not really true, because MB-02+ somehow have to bootup, so when Spectrum reset, MB-02 map the 'boot ROM' to address space 0x0000-0x07ff.
You include only a 2k BOOT ROM, but schematics talk about 64k ROM, and the manual talking about...

Feature req: MB-02+ emulation - ID: 2832531
Here is a very first patch. It does nothing but page in the boot ROM (nice animation :)
I think, first i try to implement the emulation without RTC/PIO(LPT interface) and with a very minimal Z80 DMA.
