    Default Everdrive…how exactly does it work?

    I can’t find much on the internet about this. I find it pretty cool that the Everdrive can run Master System games and even NES games, but how does it run these? Does the everdrive have an internal chip that helps these games run like a mapper or is it some kind of emulation? Same question for 32x and Sega Cd. It would be pretty cool if these games can run natively using Genesis hardware.

    The Mega Drive hardware is backwards compatible with SMS/Mark III games. The only barrier to playing most of them is physical. So loading SMS roms is no big deal.

    The Mega Everdrive Pro has an fpga in it that has a WIP NES core written for it.

    The Sega Master System/Mark III are also backwards compatible with SG-1000 games. The carts are physically the same as Mark III, but almost all of the roms work fine on a SMS.

    What does the term ‘core’ mean? Is that an emulator?

    It's a blob you drop on a FPGA.

    Like other FPGA NESes, yes, it's an emulator.

    The mega everdrive pro is sort of an add-on console (think 32X) that can run games on its own (the nes core, the doom port, SegaCD games...) without using the original MD (mostly to passthrough the video signal), so yes it's emulation disguised as a flashcart. Older Everdrives are pure flashcarts, though, as the cpu power present on the cart is just used to load the rom and pass it to the original console (and for sram saves, region unlocking, things like that).

    so:

    MD and SMS games: run by original hardware
    SegaCD and NES games: run by internal fpga present on the cart
    Lists of MD games: officially licensed (~925) @ cart sizes @ Top 5 @ Top 250 @ Sonic hacks @ best title screens @ Arcade ports (150) @ best European games
