There may be a set up process we are missing, but out of the box MAME and the latest cheat.dat do not jive. I have to assume the new cheat engine has possibly different fields than the old cheat.dat - so modification of the .dat might be needed to comply?

There are many serious problems with -cheat that don't seem to be fixable on the user end. Confirming.

1st of all, this is deep update (and now in the making) so that many bugs/problems will be included.
But half of this problem is new cheat system and half is database problem (= not MAME bug).

Have you checked new cheat format code?
Try the following code.
> [ Star Force ]
>starforc:81000010:0298:0000008E:FFFFFFFF:Rapid Fire
>starforc:00006000:83F5:000000F0:00010002:Select Speed
>starforc:00006800:83A3:000000F0:00140003:Select Bullet Speed

Operation core on new cheat system is adjusted with new cheat format so that old(older) code requires to test or convert to new.
(Main problem is that current system can't reproduce several old format due to limited type field)

> The "Enable/Disable A Cheat" menu is always empty and you can only go back to main menu.
What message is displayed?
If an empty, cheat system tells why no cheat code though.

And please post a sample code together.
I don't know in case that only simple report, "cheat code doesn't be read. I use official database".
Because the cheat code includes many different operations/options/flags so I fail to identify the cause of a problem.

I attached a pic of "Enable/Disable A Cheat" menu. It's the same for the majority of games I tested. Are you in the mood to rewrite the whole database with your new code?
Seriously, the new cheat code looks like isn't able to read and display old cheats from official database.

I attached blktiger codes as an example.

It's mysterious screenshot. It has 10 specified separators and the sample codes you attached is the same number so that CODES ARE LOADED WITHOUT PROBLEM.
But special separator is only for new format
OK, I understand about this bug.
Check these codes in "Add/Edit a Cheat" menu. Is it displayed as expected?

In "Add/Edit a Cheat" the name of the cheats is displayed correctly. But if I select a cheat and then press enter, nothing happens. I'm not able to edit it.
Hope this helps.

Edit menu is too huge code so that I have not finished converting name based on guidlines.
Force to convert old code to new.
If you DEBUG build, select "convert" item in add/edit command menu.
Or by hand.
Conversion is simple. Chage first ":" in a line to ">"
":blktiger:..." -> ">blktiger:..."
