    Just in case anyone wants to try modding menu structure:
    ROM:84916C30 20 1D 66 84 F4 6B 91 84 00 00 00 00 00 00 00 00
    ROM:84916C40 00 00 00 00 00 00 00 00 00 00 00 00 FF FF 0F 00
    ROM:84916C50 00 00 17 00 00 00 00 00 00 00 00 00 00 00 00 00
    ROM:84916C60 D0 02 00 00 40 02 00 00 1E 00 00 00 1E 00 00 00
    ROM:84916C70 78 00 00 00 0A 00 00 00 00 00 00 00 00 00 00 00
    ROM:84916C80 E0 37 66 84 54 6A 91 84 04 6B 91 84 00 00 00 00

    Looks to be part of what is used for guide. The screen is likely something like 720 by 540 pixels and 0x2d0 == 720
    The 846637e0 routine is likely the entry point for the guide routines. "Guide" is the 5th or 6th entry in the menu strings.
    One would have to start playing with the entries to see what is doing what--either by modding directly, or using the
    84680000 ; "remote control on" a serial monitor debug routine?
    That last seems to be a way to control the box via serial port--you send 0xA9 to get into the monitor screen I think (maybe twice)--it should show "remote control off" or "remote control on" depending on if you get in or not. The cmds allowed seem to just do what an IR remote would get you, but that could be modified to write to RAM and change entries in structures. (or run code that you load into box or dump RAM or....)

    Easier to just log in to box via web, or just use on-line guides.

    You can see a button for detail on the lower edge of screen.

    The key to finding the code for guide is that month abriv followed by a period then 2 digit date and 4 digit year...
    You can find it used in the first routine below:
    84662C80 ; part of guide Month day "%s.%02d %s %s - " "%s [%02x:%02x]"
    84663200 ; do the guide?
    84663400 ; call to use guide
    846633A0 ; loop using call to guide
    846636A0 ; other use of loop guide

    Odds are that the guide image you see is formed by using a structure that has an index number for the text "Guide" with numbers for the size, color and positioning--maybe a pointer or two for the handling routines to use (those pointers will be right around the 84663000 part of the code you see above). This for the nf_hd_v1.3sR_25 file.
    I don't know where that picture comes from but it looks nothing like my guide, that must be just the factory file........

    I could not read the photo well enough to see the SW version, but I'm guessing they just copied the manual pages--so really early factory file.
