FMC Data Monitor?

[Peppe]

I was browsing around the internet to find a label for the FMC Disk Card Checker software since i rewrote a disk to have that program and i stumbled in this website which had the thing i was looking for:

https://eludevisibility.org/2015/fmc-disk-card-checker-v1.3-japan

But while viewing the page i noticed this image among the others...

You cannot see attachments on this board.

I've never seen this software and google searches have all led to nowhere. Has anyone ever seen this tool? Is it contained in the disk checker software? It kinda looks like it since both tools have the same font but maybe i'm wrong.

Haven't seen that either. Looks like it could give some hints on some of the header fields. ICE (version of the development hardware perhaps?) and Debug Version (different from disk version?) are both new things I think. But it only displays two bytes of the three in the game title.

Hello!  This is actually part of the FMC Checker program.  Before you insert a disk, hold down both "START" and "SELECT" buttons on your controller.  Then insert the disk and continue to hold your fingers down on those buttons.  It will take you to that screen and give you the header data for the disk as P surmised above this post.  Here's an example of the Disk Checker program itself:



Maker Code is the code for the developer of the disk.  01 is Nintendo's code.  The game's name (product) code is CHK (shortened form of "FMC-CHK").  In that other picture's example, the game name code is ICE (or FMC-ICE) for the game Ice Hockey.  Game Ver and Debug Ver, are together both denoting the disk's revision, which should be REV02.  SIDE is showing the disk side -- 00 for "Side A" and 01 for "Side B".  It then has a few other codes for other header information. 

P, I believe you are Pokun from the NESDev forums, so you know of Chris Covell's program.  But for Peppe there is a more advanced type of program now for this type of thing, known as the FDS Disk Lister.  You can find it here: https://www.chrismcovell.com/fds-lister.html

And here is the FMC Disk Card Checker as it is being observed from the FDS Disk Lister:

Oh "ICE" is the game title not a header entry. It's indeed showing all 3 characters in the title (or actually there are 4 with the final space $20). I confused ICE for the In-Circuit Emulator hardware they used for development.

Thanks for explaining how to access this screen, I hadn't seen it before.

There are two version numbers written on Nintendo's archived master disks, and they seem to match the game version field and the field that previously was thought to be price (offset $37), but now speculated to mean disk version. I just thought that this Debug Ver could be the same thing as the disk version field, but I really have no idea how this works.

I'm indeed Pokun.

Thank you all for the replies, i actually had a hunch to hold start and select but i did that after the disk was checked out, still it's really cool to know about these things. Again, thank you guys so much for the help.
