File skipped when making rollback rom
« on: 07 October 2019, 06:32 »

I was trying to rollback a rom from version 208 to 078 in clrmamepro, and it got skipped. The rom I was trying to roll back was Spongebob Fry cook games plug in play. When trying to rollback the rom into any version other than 208, it skips it.

well...I'd say that's a pretty common behaviour.
Romsets change over time. Bad dumps will be replaced, missing dumps will be added, wrong named stuff gets renamed and so on.
Rolling back (there is actually no reason to do so) would mean that you need the old sets. clrmamepro can't create old stuff magically out of nothing.
If the set/files are skipped, it most likley does not match the checksum which is required by the old definition.

You try to switch back to a version which is 16 years old (again..there is NO reason)...you could imagine that things changed in the meantime.

I don't know if it is possible, i'm a noob. But the reason I want to roll it back is because most ports of mame on consoles like wii and 3ds are only Mame 2003 and below. Is there even a way to do it?

I've already told you.
You need the old sets/files.
There is no way to magically create files which aren't part of the 2019 MAME but are part of a 2003 MAME.
You need all the files which were replaced/removed in the given set(s) in the meantime.
The ones which did not change over time can be recreated of course, e.g. by using the rebuilder.
