I'm new to the scene of hacking my dsi. What I really want to do is just play roms and watch movies on it. I don't need any frills or a ton of stuff I will never use. I did a small amount of research but most of it was 2 years old on google. I read that the r4i gold only played 80% of the roms while the acekard did 90% and you were able to watch movies on both. Acekard isn't supported anymore and not sure about R4i gold. Both of those were almost 20 dollars cheaper. So why is this cart almost twice the amount than the other two?
