Romcenter

When i decided to download kawaks 1.49 (i was using 1.46) i realised none of my roms would launch. Then i found out the neogeo bios files had to be renamed but im having some trouble. I demands that i change the EXTENSION of the file. Thats the problem see i cant change it from a .rom to a .lo. Explorer wont allow me to change the extension so im left with 000-lo.lo.rom instead of 000-lo.lo

any ideas?

You have to configure your explorer to show also the extensions for known files so that you see the true extension. (or let romcenter do it).

But romcenter will only do it if the roms are the correct ones
