MasterEverdrive Hardware Manual?

[skyfox01_99]

I've noticed that there are techincal spec manuals for both the Everdrive MD and Super Everdrive that detail the memory map/registers/config bitfields/etc. Is there something similar for the Master Everdrive so that we can use the extra features (i.e. MMC, USB, FRAM & EEPROM) from homebrew code?

i just have no time to make docs, but i can share some sources which can explain how to use SD and USB. flash usage is a pretty complex thing and easy to damage cart if some important data will be erased or rewriten

I know there are risks involved with writing to flash. I'm ok with voiding warranties :nod:
Sources would be even better than docs! What about the FRAM? Can that be mapped into the address space using the standard Sega mapper's register at $FFFC or is there a custom register provided by the CPLD?

Thanks for your time.
