rhythm paradise rom not working

downloaded the nds rom for rhythm paradise. the rom appears on my r4 revolution, however when i try to load it freezes... the loading bar appears but none of the blue bar fills up. am using 1.18 firmware. any suggestions? this is the second version of the rom i have tried, same happens to both.

maybe this would help: COMMON ISSUES threadhttps://www.romulation.org/forum/index.php?topic=1462.0
R4 revolution is a fake R4 copy by the way

i've already had a look at that... which is why i started a new topic. also i bought my r4 from memorybits.co.uk which claim they only sell genuine r4 carts?!

Did you do anything with it? Patching, etc? That will probably help, and is explained in the common issues thread.

can't run dslazy or buff on my computer for some reason
