I tried no$GBA and DeSmuME and both lag vey badly during cgi sequances. I only tried Castlevania ORder of Ecclesia and Zelda and both had problems starting up. iDeaS does this as well. Does anyone know if there is a way to fix this?
R4 was ruled illegal in Japan, so you might have a harder time finding it. That company is getting the pants sued off of it. You can try a website like DealExtreme, but be sure to watch out for pirate, knockoff carts (which is quite ironic if you ask me lol).
