Tester pat33999 View Status Public Platform MAME (Official Binary)
Assigned To Resolution Open OS Windows Vista/7/8 (64-bit)
Status [?] Confirmed Driver hornet.cpp
Version 0.184 Fixed in Version Build 64-bit
Summary 06535: gradius4: Background graphics corruption in stage 3.
Description Specific polygons (or textures) along the lower half of the screen are displayed incorrectly. They contain wrong colors, and don't fully appear until completely onscreen.
Steps To Reproduce Play until you reach stage 3. About 20 seconds in, the music and background will change, and the corruption begins to occur.

I wanted to attach a MAME 0.184 64-bit save state, but its too big, so I uploaded it to Dropbox.

Confirmed using offered Save State.
Are you 100% positive of the regression version (working in 0.174 and not in 0.175) ?

Yes, I checked and double checked everything. I can also upload save states for 0.174 and 0.175 if necessary.

With the recompiler disabled it doesn't reproduce.

Sharc recompiler?

would make sense for the timeframe I think?
