A few years back I registered as an XNA developer, but unfortunately back then there was no way for me to test out my games before putting them on the market. At least not on the console. I eventually stopped working with it all together because I simply didn't have the resources to properly test gameplay. Is there anyway, either with a soft mod or a hard mod, to port a game that I program on a PC within the XNA development tools directly to the Xbox 360 to test without having to first upload to Microsoft servers? Completely offline? How difficult would it be as well to share such a game with friends to help test? On a related question, I purchased quite a few community games. All of which require me to be connected to the Internet with the latest update in order to play any of them, even though most of them are single player games. I never play games online, but the reason why I have never bothered to mod my xbox in any way is because of those games that I might not be able to play anymore. Is there a way to play them offline? Lastly, while I am absolutely certain that any mods would be detected online and then banned, is there such a thing as a stealth mode or something like that where the mods are disabled with a real disc inserted? I would still like to purchase additional community games even after I mod a console, which is why I ask. Or would I need to have a second console unmodded, and then somehow copy the games between the console?
