Randomized Rom wont load on R4 card

[Aurath]

Hi all!

I have DSTTi R4 card, a little old I know.

I have recently become very interested in playing through the older gen games again but want to run a randomized nuzlock.

I took the time to find working DS roms and I have the Universal Randomizer.

I Randomized a Pokemon Black rom which I have confirmed works before I randomized it but it wont load once randomized.

I was hoping someone could help me as I have a PC and I want to be able to be able to play on my DSlite when commuting to work.

I'm using the DSTTi YS Menu 7.01

Thanks!
