When you deleted the game data you deleted the patch. You will need to reapply it. I would recommend that you update to Kmeaw 3.55. It makes playing games a lot easier because you don't have to use as many modified EBOOTs.
Thanks for the answers. I forgot to mention i already tried the following:
deleted all my saves for this game (yes, including my RTTS data...)
tried discless form the app_home icon and with a retail disc inside from the disc icon
re-applied the patch (that's why i get to see the move screen, otherwise it won't start)
tried with open manager and multiman (both last versions)
tried with the bdrom emu option (not useful with an internal hdd game)
i'm trying to stick with 3.41 i always managed to play every game on it. since 3.60 is out being on 3.41 or 3.55 is the same thing (the seek for working eboots/patches) and i have many games already modified, so it would be a mess to make everything 3.55 compatible for me.
to get back on topic, the weird thing is: game used to work perfectly. why is not working anymore?
Maybe your rip has been messed up. If the game requires only 3.55 I would just update to that, but yes any games you modified the EBOOTs for will have to be reverted to stock. Luckily we have a really nice repository here in the Hacks thread for original EBOOTs.
I too had issues with getting this game to work. I remember having to get 3 different sources. I'm still on 3.41 CFW myself. You do need a modified eboot plus pkg fix for this one. This is a pretty good sized game. I have mine running from internal HDD. Be sure you get a fix that is proven to work. That was my problem. I was using fixes that wouldn't work. Thanks!
Thanks again for the answers. I have a USB stick that I only used for installing PKGs. I checked in there and I have a PKG for the show 11 that I0m pretty sure is the one I installed a while ago, and worked.
Using that one, I had no luck. So, I already deleted the image. I'll re-dump it again on the internal, and look for a 3.41 fix.
