MAMEWorld Forums - EmuChat - Is Pong more accurate in MAME or DICE (or is it a tie)?

Okay guys, please indulge a technologically challenged old man (born in 1967). I'm really getting geeked about playing all the games DICE offers, though some of them run at a low number of frames per second on the old PC in my cab. Pong runs fine, though, and I'd love to add it to my MAME wheel in HyperSpin, but I also understand it's available in newer versions of MAME now (I'm running MAME 0.145, so no MAME Pong for me as it stands now). First off, does anyone know if the MAME version of Pong emulates the game just as accurately as the DICE version? Next... Even if DICE is more accurate, I'm really not sure I'll be able to pull off running Pong in DICE through my HyperSpin MAME wheel - from what I've read in the HyperSpin forums that looks like a daunting task for me (I struggled mightily in figuring out how to run a PC SIMulation of Pong from my MAME wheel if that gives you an idea of my level of understanding when it comes to HyperSpin). So, if for whatever reason(s) I would want to use MAME instead of DICE, here comes my really dumb question... If I upgrade to MAME 0.146 or higher for the sake of Pong, what happens to all the game-specific input tweaks I've made in my current version of MAME? I can't even imagine all the man-hours I've spent doing stuff like, say, adjusting the sensitivity of my spinner for Super Breakout. Thanks for listening!
