don't know

yes, if you able to write the c/cpp code for most of the modern emulators

there is no wram in 209 nor in any 90 clones if you find any in the wild. no one can stop you though to add wram to any mapper you want whatewer reason you have for this. but when you want to move to the hardware you need to modify it as well manually.

i don't know why nesdev treaten this mapper as 209 mapper clone but this is not even close to it. http://cah4e3.shedevr.org.ru/dumping_2009.php#070309 this mapper was assigned by me back in 2009 for the only game I dumped and emulated since there are no other similar mappers existed and the 35 number were free, lol.. ask nesdev why they are wrong. mapper 35 is not 209 clone, do not use it as 209 (which is submapper for mapper 90 series).

anyway, this repo is dead already, you need to report to at github/tasvideos/fceux instead
