    Hi, im trying to use the Nes emulator i can hear the music of the games (most of them seems to work) but i get no TV signal, i have N64 pal, and NTSC N64 games worked on this TV.

    Other info :
    Everdrive v2
    Firmware : 2.24
    OS : 1.28
    CIC : 6102

    Is there a way to fix that ?

    Thx.

    The NES emulator wasn't designed by KRIKzz and therefore not much is known about its compatibility with ED64 hardware. He suggested to me to make the NES emulator and ROM collection a standalone SD card. Put that stuff on another card and see what happens. If you still have issues it's most likely the SD card. Be sure to keep the N64 games off this one. just put the ED64 OS, NES emulator, and NES ROMS on it. Nothing else.

    The source has been available for that emu the whole time... and looking at it, I see exactly why it doesn't work on PAL systems:

    That's from INITS.INC, and sets the VI for a 512x240 NTSC display. Some of the values need to be changed to work on PAL. I'll see what I can do to make it work.

    ^ That still doesn't solve the issue of my setup randomly freezing with memory address errors. It's a NTSC-U setup running composite video to standard CRT tube TV.

    What games does it have trouble with? If you name names, I can try them out myself and see if it fails on my system (NTSC). One thing to note is that it only supports MMC1, MMC2, and MMC3.

    Super MArio Bros. 1,2, and 3. Never tried anything else.

    Hmm - tried playing all three for a couple hours... didn't notice anything wrong. Are you using the latest Neon64 version (v1.2a)? It will say on the title screen right after launching which version it is.

    You can get v1.2a and the source from here: http://hcs.freeshell.org/neon64.cgi

    EDIT: One more bit of info - I use the memory expansion on my N64. Maybe the extra memory helps with those memory access errors you mention. If you aren't using the memory expansion, you might try it with the expansion to see what happens.

    Cool I could test that version :)

    I thought the latest version was 1.2b (2005 release, not sure if sources available), yesterday i downloaded a bunch of them, and the readme of 1.2b says to fix a lot of PAL rom issues, and some minor things.

    Hmm - it's not on his page, but looking around, I found the link: http://hcs64.com/files/neon64bu12b.zip

    The readme says -
    EDIT: There's also a GameShark build of 1.2b: http://hcs64.com/files/neon64gs12b.zip

    He seems to have lost the source for 1.2b because he also has a disassembly of 1.2b that he did in 2010. Looking at the disassembly, it's still only setting the VI for NTSC display. The fixes for PAL are with regards to PAL NES roms, not PAL N64s.

    I don't remember what version I used since it was about 6 months ago this was happening. I assume it was the latest version since I always look through releases to get the latest. I do have the expansion pack in my machine.

    Chilly Willy please let me know if you find a way to compile the sources with PAL fixes so i can test it on my N64 pal ;)

    Im a programmer as well, but just very newbie on N64 scene, i havent set yet a proper devkit to start. :p
