My next board for building homebrews and repros is now done! The ReproPak MMC1 (available at www.retrousb.com) will handle any standard MMC1 game, including the extended variants used by DW3, DW4, and FF1+2. You can select CHR RAM, CHR ROM, WRAM, battery backup. Use either flash or eproms for both PRG ROM and CHR ROM. The MMC1 CPLD is already soldered on the board so you just need to add the DIP chips. No rewiring needed!
The CPLD jtag port is also brought out to the board if you want to reprogram it for other uses. There is lots of unused IO if anyone feels like adding an IRQ counter, but some of those would have to be used for PRG D1-6.
BTW No there will not be an MMC3 board. The logic is just too big to fit on a cheap CPLD. It would be $20+ which is just too expensive.
