If you Choose yes, Mame32 reverts to default option settings which are not good for playing back all recordings, the worst one it turns Autoframeskip On, for playing back some games you need frameskip turned off, The other big thing is oubling the display size and disabling MMX, both of these make mame look lame and play slower for me. Then there is sound settings, I prefer MIDAS when it sets it back to direct sound. Why the heck would i want to click a bunch of menus everytime i playback a recording, when with dos mame i can keep all configs, frameskip settings, scanlines settings all the same for all mame versions.(posted 9026 days ago)If you choose No, there are several major differences between mame32 final 35, 36, 37 versions, I think mostly they have to do with sound settings, and basically makes mame32 unusable if you click No. this is lame! and maybe they will conform to settings between 37 and 38 39, but i'm not betting on it. And that means you can't simply choose No and expect default registry settings to conform.
Mind you I playback a lot of recordings, I'm used to changing settings and clicking stupid GUI boxes. But if there are some that are difficult for me to playback, it will be unlikely(impossible) for the average user to play it back in the future, dos mame makes this easier for everyone becuase settings are consistant through out versions.
