I have done a tutorial for someone but then wanted to post it here.
This method is by using Geex

WOW!! Looks great!! I'll wait for the full release so I can publish to Xbox, but it looks FANTASTIC!!
You, sir, are my newfound love! Great job!

Will this work with RPG Maker VX games?

Nope. Only the default scripts for RMXP have been transcripted to C#. But you can do it yourself if you know C# (it's actually fairly easy) and if you don't, you probably shouldn't make a game with XNA to begin with.

sweet but you can just put RPG maker on your XBOX ..... somehow but i forget anyway thats pretty cool know all i need is to do this with FPS creator...

No, RMXP games can't be ported on the XBox like that. Nor on the DS, or the PSP, or any other console. Geex just convert the database files to XML files and create a C# version of the default scripts (both Ruby and C# are OO programming languages, so keeping the same structure is farily easy - although Enterbrain's coding style for RMXP is awful but meh).
Technically, you don't really port XP games on XBox.

True RPG Maker XP on xbox just seems....Blah
microsoft already made a converter for Gamemaker but i think its deleted

Anything on the xbox is Blah.
We have those rpgmakers on the PS1/PS2...Too bad they're crap.

its not that Xbox is blah well xbox isnt blah..... rpg maker xp on xbox would be Ok and its preety easy to use PC games on Xbox

Ps3 dosent have its own game creator so you can just do some stuff on xbox then you can use the media on your computer on your xbox plus you can use XBOX [/size]Controllers wired or wireless for PC thats how i play my RPG mkaer games with my XBOX Controller

Kinda driftin' off topic here people, this isn't about xbox being blah or using xbox controllers to play XP games.

Quite frankly I think this is a fantastic idea. Gives a MUCH easier game making device for XBox 360. And you can make mini games, it's not like it has to be a huge game with HD graphics or anything.
