Quick answer is you should be able to. Since, they are fundamentally the same programs and should record the input states the same. Long answer is: don't expect playing back dos mame recordings to work with mame32 program, since certain games do not playback correctly with both platforms after recording in one. I think there was a WinME help thread around here.(posted 9029 days ago)ALso, if you are trying to playback a dosmame 35b10 recording with mame3237b13, it aint going to work. you'll need to find the correct mame32 version correspodning to the dos version, and jump through lots of hoops to install a new mame32 version.
That's why i dislike mame32 recordings, they are really only good for the few weeks that a mame32 version is available and everyone has that on their desktop. The hoop jumping scenario: you have to first bakup your MAME32 registry, then nuke the registry, unpack the mame32 version you want, Wait for it to load, then get the settings back to how your computer can play it, THEN you can try to see if an old mame32 inp will playback. Of course some will say you don't have to backup your registry, but there can be playback problems induced by wrong version registry settings, which forces you to maintain registry state. dos mame playback is always SO simple: unpack the exe mame.exe -playback recording. All settings are stored in mame.cfg which is compatible with nearlly all dos mames.
ok my 2 cents is shared. off box of soap.
