missing GG lem/zem

[samphex]

I just started using ljp on my centro(yes I read the centro post and downloaded the specific RC version) Snes and sega seems to be working fine (except for a few roms which im guessing are bad dumps), but I noticed there is no zem/lem file for GG in the download pack.
Is there supposed to be one or no?

PS I noticed an extra file called "mikmod" in the folder. Do i need this for centro? What exactly is it for?

GG is done by ljp-sms.zem. Mikmod is a free mod-player engine. As far as I know it isn't used atm. Itwas used for the launcher to play background music.

so all I have to do is just put roms in the GG roms folder and it will use the sms zem automaticcally?

yes, exactly
