Sorry for the confusion here, but when you play an Xbox original title you will be disconnected from LIVE during the duration that you are playing that game. This means that you will not be able to chat with friends or send messages from your console.
This is a limitation contained within the emulation software.
Also before you purchase an Xbox original be sure that your console has an official Xbox hard drive. Original Xbox games do not work with 4GB console without a hard drive installed.
Did this solve your problem?
Sorry this didn't help.
