iv'e been using a version of vsync mame that
was updated by some Asian guy,
its great it uses newer rom sets and runs under dos.
I really like it, it lets you move your screen position about,
and is generally very smooth,runs games well,i think it is unofficial and
not really meant to be used - the guy has not posted source
for some reason?, but I found it a great alternative to
advance Mame for dos.
I wish that the person who made it would make it more official
and post the source as this would let others use it.
I now use advance mame and this vsyncmame version ,but this has been really cool and easy
to use.

while its a bad move to not play the game properly
and release code, Im pleased with the program and
glad that its been updated, which is better than nothing.
