---------
and question is : that is normal because cmp wanna safe mame structure or again mamedev bug ? Tnx

[Roman]

Well...the "wrong mergetag" warning comes up if a rom or chd with a merge tag A and a checksum X points to a rom/chd with name A but checksum B...

so..maybe MAMEdevs should double check this...since it seems to be a wrong entry within MAME....

..but yes...I will also double check it tonight (it's 9 am now...)

[Roman]

hmm...a quick look at the data shows nothing really bad....
I will look into this more deeply tonight...could be something on the cmpro side...thanks for reporting

[Roman]

ah ok....disks within a bios set (and the merge check only looked in the parent for disks)...something new ;-)

I will fix it as quick as possible....

Update:
As quick as possible means...NOT TODAY/TONIGHT ;-)
It takes a bit more effort needed as I thought...but most is done already...generally it's the first time where bios sets contain chd(s)...sounds easy...but yes..I actually did forget this possibility....so I need to add some things here and there....
If everything works out well it should be in a testable state tomorrow night....if not you may have to wait till next week since I don't have time over the weekend....

...since the next MAME release comes in two weeks I should have a little bit of time ;-)

[Roman]

ok here we go...testing "chd support for biossets"...

Hi Roman, now testing , results is : cmp removed all duplicate chds and create new folder "lindbios" - inside with this chd.
Maybe correct because all lindberg games have
<game name="blablabla" sourcefile="lindbergh.c" romof="lindbios">.
U say "something new" - future chds with bioses

[Roman]

"maybe correct" ..hahaha...of course it's correct... you don't want to copy a large chd which is part of the bios in each and every set which uses the bios.....

[oddi]

Uncle oddi say: correct !
Tnx Roman
