First of all hi everyone. I've been trying to play Contra 4 since it was released but I was unfortunate. I got both Donkey Kong Jungle Climber and Contra 4 on my card but when I tried to run them I got either "error reading EEPROM" or something like "unable to read game data please reinsert game card." However, as I found out from the forums I should have updated the U-Disk Manager from G6. After doing so (altough I found online the 4.9e version but in the title of the application the version 4.9c is written), Donkey Kong runs just fine without any issue but when I attempt to run Contra 4 the screen just turns black without writting any message. Any other types of fixes I should do? Thanks.
