Good to see these GDROM baddumps are being updated. Thank you.

Regarding this commit and these other two:

Is there a way to use chdman.exe to perform the conversions?

I assume one uses a recent version of chdman (copy command) to convert the metadata to the "CHGD" type, then uses chdman v0.146 to do the metadata manipulation (save metadata/remove metadata/edit padding values/add metadata), then uses a later version of chdman (copy command + "-hs 19584") to flatten the metatdata into the header and get the final result with a hunk size of 19584.

Using chdman v0.184, I'm getting close, but the sha-1 doesn't match and the "CHD size" is still a little off (too high). Using the v0.185 wip version of chdman gives the same result as v0.184. I'm hoping that some other version of chdman.exe (between 0.146 and 0.184) may work.

Does anyone know if a particular version of chdman was used? Or am i completely barking up the wrong tree?

in this case you can't simply convert older CHDs to v5, that's why they was marked as bad for a long time.
in general you have to:

  • extract image to GDI format - "chdman extractcd -i xxx.chd -o xxx.gdi"
  • truncate track1 and track2 to correct size:
    -- track1 have to made 352800 bytes smaller,
    -- track2 size for Triforce and Chihiro must be made 3179904 bytes in size, for Naomi 1/2 its more complex, few options possible: Naomi1 - 5016816, earlier Naomi2 games - 5049744, later Naomi2 games same as Triforce and Chihiro - 3179904
  • if source CHD was v5 - byteswap track2
  • convert image to chd using "chdman createcd"

Thanks for this conversion info.

Please do not perform this step if you have any questions; it is MUCH safer to just download the new CHDs when they become available.
