Why don the developers put more hacks in MAME?
Hacks, while maybe appearing to be good in a short perspective, are always bad and destructive in the long perspective. The more hacks you put into the code, the harder it becomes to make new additions neatly as the hacks will require workaround hacks, so you’ll end up on a downward slope of more and more crappy hacks, until everything collapses under its own weight. Hack-based emulators typically have a short life because it quickly becomes impossible to debug or extend them.
