I have a bad feeling about this:(posted 8531 days ago)
"d. Version(s) of MAME allowed[...]it MUST playback in MAME and MAME32, unless the version is 0.51 (m37b15) or higher - then it MUST playback in MAME only. (MAMEW) "
If "some drivers call the rand function to generate random numbers and the implementation of this function depends on the library of your C compiler, which means that gameplay will differ and inp files won't be portable across platforms"(Example:Solomon's Key),that means for some games we CAN'T have a valid recording since it MUST playback in MAME and MAME32(they are like the day and night you know)or MAMEW when a person with minimum of "mental power" play with DMAME (Reason:much more faster).
I think is a hassle this thing...
