Thank you so much for what you do every day and for this post.  I am completely ignorant on the subject.  Could you tell me what you need to download from the server to get the latest updated version?  And could you also indicate a guide for newbies like me, on using a rom manager and how to use it with the contents you update with the server?  ... I would never want to make a mistake or corrupt the roms given the amount of data to download.  I downloaded "Currentsrom" "CHD" "Chd_temp" "bios" "rollback" .. What should I download?  Full.0226?  ... I'm sorry but it may be useful to know it in detail to ignorant people like me.  What should I do on the mame application to show the roms?  How should the folders be set up?  Does the bios go with the roms?  Do the chd go into the roms?  I apologize in advance to you and the more capable in here ... But even though I see guides, many differ from each other and send me into confusion.
