MasterEverdrive Hardware Manual?

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.

 

yes, you can use standard sega method for fram bank switch

 

sms os sources and small usb listener source

 

Wow! Thanks for that. that has everything I need.
