I understand it is recommended to use the up to date MAME version and the updated rom set but I don't understand how that works.
What changes are made into the rom files?. I just read people said roms get new and better dumps but let's take a very specific example.
Tecmo world cup 98 twcup98
This game has a weird bug where randomly the opponent goalkeeper freezes and you can't continue playing but the thing is this game runs kind of good besides that bug in a very specific version of mame I think it's mame 2010.
But I just tried a more updated rom and MAME and the game runs too slow with cracking sound making it unplayable.
What is the explanation behind this ? There is not much information about what changes are made between rom updates how do I know if twcup98 has a new dump or why it's running worse in newer versions of MAME.
