Help with Megaman Pegasus

Hi everyone, this is my first post here, and I hope im posting in the right spot. Anyways, I use the R4, and while most games work, some games, such as megaman pegasus, always bring up the message...could not access the data. Turn the power off and reinsert the game card.I turn the power off, take my R4 out and put it back in... and nothing happens, the same message appears. Does anyone know what is wrong and what I can do to fix it?

The same thing is happening with me, but its not just MMSF Pegasus, it happens to me with the dragon and leo version as well.

Refer to this thread : https://www.romulation.org/forum/index.php/topic,816.0.html tutorial to upgrading firmware for R4/M3 so it can play most of the newly released games like megaman dragon, pegasus, and leo.

Just go to the R4 website. Load the new data version1.1 I think.Anyways. The starforce game is kinda fun although the BNW is better.
