neogeo cache help

[l1nknp4rk00]

i have neogeo psp running on my 1.5, and got 1 game to work but the rest say something like cant allocate region GFX3_memory and i was told in cases like these use the cache files. but how do i use them, what are they, and where are they?

It comes with the emulator NJ made all the last versions. All you need to do is click on the romcnv and it will give you a window to choose the ROM to format then choose the ROM it will create an extra file kind of like the ROM file and you will put that file on your cache folder on the emulator.
