Metal Slug NEOGEO [NPUB30258]

[tambre]

Thanks for a fix

Using OpenGL have no errors. I reach menu, select normal mode and just now loading creen lasts forever. No error, it just loads and loads.

yes indeed. Game uses some emulibraries. I decrypted all dats. There are also two prx modules: libaac_neogeo and libemu_m68k.
Copying them to other lle's prxs and enabling them on the list gives no help.

LLE'ing them won't do anything, as they're not system libraries.
Games can have their own modules (as in this case), that they can load and then call functions from. Kinda like .dll's.
