Problem with FDS roms from Wii U Virtual Console

[nnssxx]

Hi, I checked the dumping guide but couldn't find answers so I need some help.

I'm in the process of checking my NES roms obtained from Wii U VC content.
All .nes files are fine (I'll do a separate post with my results), but I'm having trouble with the .fds files: I've got zero match from DOM database, so that tells me something isn't right, even if all the games are playable

Here's an example for the Japanese version of Ice Hockey (FBUJ01):

Code: Select all

----| File Data |--------------------------------------------------
System:             Famicom Disk System

----| Side A Header Data |-----------------------------------------
Block Type          01
Disk ID:            *NINTENDO-HVC* (Ok)
Maker ID:           01 (Nintendo)

----| Side A File Data |-------------------------------------------
| Type |  No. |  ID  |   Name   |       Size       | Address |  Target Area   |
+------+------+------+----------+------------------+---------+----------------+
| 0x03 | 0x00 | 0x00 | KYODAKU- | 0x00E0   (224 B) |  0x2800 | 0x02 (Picture) |
| 0x03 | 0x01 | 0x01 | HOCK.CHR | 0x2000  (8192 B) |  0x0000 | 0x01 (Tiles)   |
| 0x03 | 0x02 | 0x02 | HOCK.PRO | 0x8000 (32768 B) |  0x6000 | 0x00 (Code)    |
-------------------------------------------------------------------

The image matches the disk version (minus the headers) except for a few blocks (2F to 31 & 38 to 3E to be precise).
I'm no expert, but am I supposed to do something to the .fds file before I check the hash values in DOM?

Thank you.

You probably extraxted with wiiu vc extractor, which doesn't extract the full qd-rom with 65536 bytes. Instead it converts to the fds-format with 65500 bytes. We haven't added these fds-conversions from Virtual Console to the database, and it won't match the retail dumps because of header differences.

You were absolutely right!
I was able to retrieve the proper QD image from the Wii U RAM dump (=decompressed ELF) and now the checksum matches.
Thank you!
