Whoa~ that topic wasn't expected by me. (Altough I should have expected it...my fault).

Anyway~
I still remember coding for DS and I can say that RPG Maker can go and [beep] itself in depths of hell. It is good tool to learn how to make a game to make it good, to get the idea for the final product. However if we are talking about making a game (homebrew of course) for a console, portable to add, only coding goes there, accept no substitutes.
Now after all this big talk there will be questions like "oh yeah? so can you make it?". I cannot say I can make it for sure but I can try to make it with some people willing to help. Of course a lot depends on the type of the game, access to some graphics (or someone who can make them from scratch but not sure if that's necessary here) &c.
I remember playing few titles like Digimon World 3 (PS), Digimon World DS (DS), Digimon World Dawn/Dusk (DS) and probably some others in that style, RPG style.
That type of the game I would gladly try my best to make it happen, I have only one condition for it, Renamon is playable (well as "catchable" I mean obviously).

Phew there we go, Subaru makes another wall of text, duh!
