>>11838139I have an N8 Pro Fami. It works great. I have no complaints with it. The Regular N8 isn't in production anymore, so the only way to get one is to buy a bootleg.
As far as the differences between the two models goes, you can read about them in detail here: https://nerdlypleasures.blogspot.com/2020/05/the-everdrive-n8-pro-second-time.html
Menu navigation and ROM loading is faster on the pro. The pro has more accurate sounding expansion audio, and unlike the original, it lets you adjust the levels of each expansion audio channel to counteract differences between hardware revisions. The only way to handle disk swapping in FDS games in the standard model is through the built in auto-swapper. This works for most games, but in rare cases fails which causes compatibility problems with some FDS games. The pro model gives you the option to control disk swapping manually with a button on the cartridge, circumventing this issue.
The pro has a slightly larger library of supported games. It supports 61 more mappers than the original, but most of these are only used by pirate carts and not unique games. There are some homrbrew games which are affected by the mapper support, however. To see what mappers are not support on each model, see:

Most of the difference in library support comes from the maximum ROM size. The standard model only supports up to 512 KB of PRG memory and 512 KB of CHR memory, while the pro supports 8 MB of each. This doesn't affect any officially licensed games, but it does affect some unofficial releases and ROM hacks. Most significantly, Action 52 and the Metal Slader Glory fan translation only work on the pro model.
