20 EX missions acheivement won't pop!
I know this is a long shot, as it seems pretty dead around here, but if anyone could help me it would be greatly appreciated.
I have 98% of the EX missions...I'm missing Battle>Grab>Stage 4. I'm assuming that's the 20th and final mission? The one you get from beating the game with all other 19? I'm pretty sure I have every other one, but I beat the game after getting the one in the Vic Viper battle and it didn't unlock. Then I read about the glitch where you have to load a completed save file before starting the game. So I loaded the file and completed the game and it still didn't unlock! Am I doing something wrong or am I screwed?
Also I did the Zoradius mini game and didn't get the achievement for that either...Is it because I used the Konami code? Or do you have to get the high score or something?
