What games are supported?
All games except Banjo Tooie and Animal Forest. Donkey Kong 64 and Jet Force Gemini need a crack. One source says Banjo Kazooie needs a crack, although I've been using an unmodified rom and haven't found any problems so far.
What CIC do I use?
PAL systems need a 7101 CIC, while NTSC units require a 6102 CIC. You can use a 6105 CIC which will allow you to play Banjo Tooie at the cost of some 6103 games. Use a 6102.
Does a PAL console play NTSC games and vice versa?
Yes. You may get a grayscale picture playing PAL games on an NTSC console depending on your TV. The same issue does not occur playing NTSC games on a PAL console.
How do I crack Donkey Kong 64, Banjo Kazooie and Jet Force Gemini?
"Jet Force Gemini (E) (M4) [f1].z64" and "Jet Force Gemini (U) [f1].z64" will work for JFG.
Banjo Kazooie needs the "Banjo Kazooie (U) V1.0 [f1].z64" rom.
DONKEY KONG 64 HELPZZZZZ
Something new comes out every day with this game. Check this thread if what I say here isn't working.
If you are using an NTSC system update to the latest OS (1.27 at time of writing) use the rom "Donkey Kong 64 (U) (f2).z64" and force SRAM.
If you are using a PAL system update to the latest OS use the rom "Donkey Kong 64 (E) (f1).z64" and force SRAM
What ROM should I use?
Whether you are using a PAL or NTSC N64 more often than not you should use a (U) [!] rom. The exceptions are a few Rare titles such as Banjo Kazooie. Check the link below for more info.
Some out of region games have audio pitch errors due to PIF issues. If your using a PAL machine and you come across a problematic game it might be an idea to use the (E) [!] rom.
The only other exceptions are Jet Force Gemini where you want the [f1] rom and Donkey Kong 64 which needs the [f2] rom. Remember to force SRAM if your playing DK64.
I don't know what the (Mx) in some roms means, but the roms seem to play just like the original game.
Games which have multiple versions are given the (1.x) in their rom symbol. In general use the latest version as they contain bugfixes. The link below explains the differences for Zelda OoT
How do I use a custom background?
Get the image you want to use in BMP format at a 640x480 resolution. In the ED menu highlight the picture and press the C down button.
What SD should I use?
Use an SDHC card class 6 or 10. Do look for genuine brand name cards, if an eBay seller doesn't state that his cards are genuine then ask before buying.
A new firmware/OS update was released; where do I download it from?
OS updates can be downloaded from the link below. Put them on your SD card in the directory ED64/OS64.v64 and your good to go.
Firmware updates are not necessary on a V2 cart. If you buy an ED64 today you will never need to worry about firmware updates. Click the link below if you have a v1.01 card and hence need them.
I have a v1.01 cart. How do I update the firmware?
A new OS update came out and now something has gone wrong.
Go back to the old OS and make a post explaining the problem.
How do I get NES games to work?
Download the file in the link below and put the it in the directory ED64/emu.nes. The NES roms can go anywhere on the SD card. This emulator is not made by KRIKzz and is not very good. The MMC 4 and 5 chips do not work, probably others too. This means no Fire Emblem or Castlevania 3. The frame rate seems choppy to me, although I don't have a NES to compare it to. It requires a controller pack to save your game.
What about the Gameboy, SMS, SNES and other emulators?
The NES emulator is the only one worth using. Don't bother.
Does the Everdrive support controller pack saving?
That is impossible without romhacking because the ED64 has no access to the data stream. However, an OS update will be released which allows you to backup your controller pack to an SD card.
