+1 to Nathan, Shopkeeper are those user from Kaskus or Indowebster that usually know more bullshit rather than the real stuff. Usually they never play on other forum like this forum for example.
also, to Nathan, the shop here are actually selling rom, and hit it with a price about a bucks, 3 games. Usually pre-patched, so their flashcart like GEi, or R4 can work just fine. These shops also believe that DSTWO, Acekard, and CycloDS is not as good as R4. It's normal here. Stupid eh?
