Elvis hasn't left the building yet, the fat lady hasn't sung either, and NJ's apparently not through with MVSPSP, or so Jungle-Cat tells us. Although this is just a minor bug fix, and it only gets bumped up to v1.51, and he still says it's a "final release"; the dev is still quite concerned for his creation. Quite enough to update the last final release. Here's what NJ has to say (or how Google translates it):

Because it seems that mslug4 does not operate normally it corrected. Because the memcard folder was not drawn up automatically, it corrected. At the time of DEBUG BIOS use it corrected the fact that the picture transforms. Already truly end. Above this there is no intention of attaching one stamp, is. mslug4 it freezes still? Once, it tried playing some time ago to the ending, but problem does not occur. Now trying, after all, it does not freeze. It is from the [wa]. When UNIVERSE BIOS is used, when WORK ROM TEST is indicated in the time of the first starting, opening one time menu, you close, (clears texture) with the test ends immediately.


(Exceeding the texture size which the quantity of sprite guarantees, speed is thought just has decreased with substantially, but as for correcting with other BIOS influence it probably will put out to speed because is, leaving.)
