But the N64 Neo Myth still has some features which the offer flash carts don´t and will never have. For example the backup ability of save files! With the current menu you are able to backup the save file of any game from your original cartridge.
It's a cool feature for those who own original cartridges, but we both know that the majority of people who buy flash devices do it to play pirated games. I guess what I mean to say is that it's an added extra that most of the potential buyers wouldn't even use.
The only thing I could wish for when it comes to the Neo cartridge is for someone to clean up the mess that is the Neo Manager, plugins, menus and the rest. Truth be told, when I got the thing to work the first time, I didn't even know how it happened. As in, I installed, re-installed and updated various components, and when it finally clicked, I left it alone. There should always be a SINGLE download with the latest and working stuff in it.
The feature you mention I'm unable to use. Why? Because the menu doesn't really work for me. I also have absolutely no idea how the saving works, and that problem isn't limited to N64 alone. There should be an "extract save" option in the Neo Manager that allows you to see individual save files. I don't know what type of saves are supported [aside from games that use the external save pak].
Having a standard CompactFlash card with MyGame.n64 and a corresponding MyGame.sav is a dream come true compared to the headache that is Neo cart saving and save extraction.
For a variety of reasons, Neo Flash products often fall short of the competition. I got the MD flash cartridge as well. Previously I bought the MegaCart, which doesn't have nearly as much space and doesn't use USB, but it simply works. On everything. The Neo cartridge doesn't work properly on the WonderMega, which I use as my primary console. It returns to the menu when the image is supposed to boot.
P.S. - I completely forgot about the EverDrive 64, which is another easy solution that requires no PC end software whatsoever. It supports CIC emulation [how this works exactly, I'm not sure. Apparently, you need to have a CIC inside of the cartridge, but the emulation takes care of the rest, so you can run just about anything without a problem], loads everything off of an SD card and has integrated NES emulator to top it all off. And, it's $99.
