Williams Arcade Hits - reprogrammed or emulated

[Tom M.]

When I play it I am always fascinated how this compilation resembles the original coin-ops. The guys behind it definitely did a great job. I was just wondering if they emulated the things or reprogrammed everything from scratch.... because it rather seems it is an emulation running on a relatively slow system...

According to Wikipedia (like its a believable source lol) only the PS1 and PC versions were being emulated.

And i doubt they reprogrammed them from scratch, seeing how the game was developed by Digital Eclipse but published
by Williams themselves, i think its safe to say that Digital Eclipse was given the original source codes of the games.
