There was confusing game renaming in the newest mame (Mame 0.61).
"pspikes" was renamed to "pspikesk"
and a new rom was named "pspikes".
So now, all the recording listed in MARP under the name "psikes" were
actually made using "pspikesk" romsets.
So all of recordings should be moved to "pspikesk" i think.
The same story was a few versions ago with "stinger" and "stinger2", the situation was more dramatic then becouse new set "stinger" was a lot easier then older one.
I think somebody should decide what to do in those cases, or there should be a poll here or whatever.
I'm the one who added Power Spikes world version,and I've changed the old zipname from pspikes to pspikesk due to MAME rulings(i.e the World version should be the main set if available).So I think too that the old pspikes should move to pspikesk...
