ROM files structure

[VELESOFT]

It's my new project in development:

PROFI INTERFACE for ZX128+2:

- contain CPU Z80, FLASH EPROM 512kB , 1MB SRAM(+battery) , CPLD, extra NMI button

This interface can emulate memory paging of russian ZX clones (ZX PROFI, PENTAGON, SCORPION, etc...). TRDOS rom mapping will supported (work only with ramdisc in 1MB memory). All paging ports will readable, all features will changeable. For example - part of extended ram memory can emulate rom (will set to low 16kB as zx rom replacement with write protect). This enable modify zx roms, trdos , nmi menu, etc.....

Actually I must create content for this 512kB FLASH EPROM. My idea is join 4x 64kB rom (first 256kB) + one PROF-ROM (second 256kB).
