mamemore is a very nice emulator and i also use it
. (my fav mame emulator)
anyway you can find all the files for most roms on irc(use a irc client like mirc for example) in:
room name: #mamechannel
use the command
@find [filename you want to find]
well if you dont know how to download from irc then here are instruction otherwise nevermind
-you will get private messages if the file is found, showing you matching results, by that users fserver which will show you the location of the file on their irc fserver. the files usually have information about them like checksum, size and file directory. also a trigger, which starts with an "!" exclemation mark.
-use the: /dccallow +[nickname]
in the chatroom to allow the user with the file to direct connect with u and transfer, as the name goes. the room also tells you to do that when you enter.
-you type the trigger into the room with exclemation mark. and you will get a private message from that user's fserver. you communticate with it in that private window and its very similar to ftp. you can use the DIR command to view the contents of the folder ur in. you go to the file directory indicated in the private message earlier using the command CD [directory] . you can only go to a directoy one at a time so you can't type: cd mame\games\r0m.
you have to type cd mame , and when you're in mame you can type cd games etc... till you get to the containing folder dont ask me why. thats just how it works
-in that folder you use the command: get [filename]
info like checksum is also usually part of the file name. the download should popup (mirc) or you might have to wait a while because ur in queue (which it will say)
when its done of course insert the files into the game. its a bit of typing (imo) but you get used to that. its pretty straight forward and simple.
i heard about this channel from a friend who saw it on the MameMore homepage
i hope im not violating any forum rules by doing this
