Just as an aside, are we talking 'ROMS' here in more recently terminology meaning 'any' title for the Atari (typically single/mulitple part or self-extracting binaries), or more in the sense of a 'ROM' being a dump of a ROM from within a cartridge, e.g. Pacman, Defender etc?
Most likely the first, but thought I'd check, in terms of the AtariMax flash-carts its doesn't matter too much except the Cartridge binaries are limited to the non-bank-switching kinds, though some of those have been re-worked to work on a FlashCart, e.g. MAC/65.
There is also the S/XEGS RAM cart project which might be what you need?
