I had bought Castlevania PoR because it was cheap and Im a CV fan. Its still shrink wrapped, I dont want to open it unless it is necessary. I am using an R4 with a 1GB SD card (toshiba brand I think). I dont want to get the rom, start playing it and then find out it doesnt work and then have to start again on a real cart. Will I know early on whether it is compatible with my gear?
