There are a couple of 573 games that get upset if the RTC dies and won't run until it's reprogrammed, but it's usually just a specific game code that needs to be stored there & it's easy to fix that.
The cart isn't the problem, pretty much all the carts in MAME have been built by hand.
There is flash on the motherboard that stores the game program, which gets overwritten when you install a new game. Most games have the program on the CD, except for the original DDR which just has an audio file with the bishi bashi theme on it.
We have the B revision of DDR1 (internet ranking version), which is what usually turns up on DDR1 cabinets. I don't read Japanese but the title screen appears to say which version it is (the word VER is in English). In test mode in the bottom right the one we have says JB. I don't know if it was a paid upgrade, but as it encoded your score in an onscreen code that could be posted on konami's web page there would have been a lot of pressure by players to have it installed.
If you do find the original A revision then currently de-soldering the flash is the only way to dump it, although I will be working on a CD/BIOS/flash card (*) that will dump the contents over RS232 as there are some other 573 games that were released without a CD drive & it'll be easier if it can be dumped in place.
(*) at least one of these, maybe all.
