After 5 years, I'm still wondering what came out of this conversation! I am deperately looking for a decent hack of River City Ransom, or even user friendly tools to edit maps and such. It seems all it needs is to have the right people with the right interest in this game.
I played around with Denzquix's python scripts and extracted in-game text, npc names and shop names, that's all I managed to do.
With all the new releases around the series on the 3DS as of late, there's never been a better time to bring new life in this game!
Is there a Japanese famicom rom hacking scene I should be looking into?
