Problem Loading Roms

Hello,

I have recentrly installed Lakka in a old Pentium4 pc with real machine joypad with iPAC, first, Lakka didnt recognize the ipac but i was able to lunch ROM (Sega mega drive) and play with keyboard, I uploaded Lakka to last version and now, ipac works but when load the Rom the screen is black with the Lakka logo and i can only do cntrl+alt+supr to restart lakka. I see that core info say “no core info” and when i click on load core nothing happens.

I hhave deleted retroarch.cfg and the new is generated but no works.

Can anyone help me?¿

Thanks

i did a clean install and all works ok now.
