I'm trying to run Macrofire 3.2.8 (the newest, if my google-fu hasn't betrayed me), but the menu doesn't come up when I press both volume buttons.
I've copied the prx and ini in SEPLUGINS, enabled them in game.txt, pops.txt and vsh.txt, and checked that they are enabled in the recovery menu. I've also checked that the buttons are properly configured in the ini file, and they are. I honestly don't know what else to do.

PSP is 1000 fat, firmware is 6.39 pro-b7.

Thanks.
