How does the everdrive work?

Yeah I had previously opened an old extra Baseball, a lot of the early or standard games just have those half-height boards so there's a thick plastic ridge built into the case that prevents the Everdrive from fitting.  There are so many shell and board variants out there that like you said, pretty much every single one is gonna be trial and error.

Would the taller Namcot or Jaleco carts be better by any chance?

L___E___T

I can confirm MMC5 cart shells are a no-go, as is Family Basic (I had a faulty one). 

Haven't tried those taller carts yet, but have a few opened Namcot carts to test with. 

Seems a shame to use black carts though as you miss out on the lights.

Does the everdrive store the selected ROM in some kind of temporary storage while playing? or it plays it directly from the SD Card? I ask because I know NVRAMs and similar devices tend to wear when overwritten like 10000 times or so...that would lead to the everdrive dying some years from now.

Thanks!

it can't play directly from sd card. Latency is so huge even for famicom's low speed CPU

it uses dedicated flash memory chip to store the selected ROM. Typical wear is 100k write cycles. That's enough for loading 100 roms everyday for a couple of years. No need to worry about flash chips wearing while new chip costs few $ and you can replace it easy if you are good with (de)soldering tools. If not ask hot glue or apollo boy to do that  ;D

The famicom everdrive actually uses RAM to store the rom data... it grabs the game from the sd card, splits it across 2 ram chips and runs it....
Other ram based everdrives are the Mega-ED and the ED64... ofcourse the upcoming NES-ED will be ram based too. All other everdrives use flash .
Basically , the ram based everdrives will last MANY years unless they develop some other fault...

oh i was wrong  :(
but i want to say that no need to worry about flash chip wearing.

SRAM is even better

That looks amazing! I wish I could find a good deal on Salamander...

What is a decent price to obtain this game? I am getting clear for my NES N8 and would live this for Fami.

One last thing I have created a simple user manual for N8, I will be releasing it soon in next week.
