AS I HAVE SAID, there are many games that you can run only with the 64 bit version which is why I disagree that Win98 and Win2k is the best choice. STOP saying that you don't need a 64 bit version of Mame to run the old games. Nobody is mentioning these old games EXCEPT YOU. I KNOW 64 BIT MAME ISN'T NECESSARY FOR THOSE GAMES.
Even for older games, its is in fact stupid to say that Win98 and Win2k is the best choice unless you have very old hardware. WinXP will run older versions of mame just fine on most of today's hardware. As you already know, it all depends on what hardware you have, what version of Mame you want to run, and what roms you want to run.
Try to read my qualifying phrases in my remarks. The point I was making is that you cannot make a blanket statement about which OS is best without asking what their goal is. That's why I brought up the 64 bit version. My point was NOT that the 64 bit OS is best for most people.
Hello? My point was NOT that the 64 bit OS is best for most people. I don't even run the 64 bit version of Mame. I run an older version of Mame because I don't run a C2D. When I get a C2D, what will I run? It damn sure well won't be Win98 because IT IS NOT THE BEST CHOICE.
Here's a fact for you:
If the question is:
Which OS is best for MAME?
And you don't know ANYTHING else such as what hardware, what roms to run, version of Mame, etc..
The best O/S for Mame is a 64 bit O/S.
Pose the question to the Mame devs over on mameworld as many have already done. Ask them which O/S is best for Mame irregardless of hardware, roms, etc... and see what they say. Better yet, do a search and get the Mame Devs responses from the past, then come back here and beat the drum for Win98 and Win2K after they tell you Vista 64 bit.
