Hey guys, I’ve been playing Pokemon Clover a lot lately, and was curious about how difficult it is to edit Pokemon Fire Red. Turns out editing maps is pretty straightforward – there’s some robust tools for that, and the game seems to handle the changes quite well without crashing. It’s a bit more complicated if you want to add your own graphics, but I was happy enough just making my own version of Pallet Town with the existing tiles. The grass is populated with Weedles and Caterpies and Missingnos.

Changing Pokemon graphics was tricky though. You need to learn a bit about how to change pointers and use empty space in the ROM, so that you don’t end up overwriting any essential stuff while adding your new content. It also took me many attempts to get the color pallet right. Some of the tools used are very primitive, and just installing the text editing tool was a huge pain. What you see in the screenshot below took me 3 hours! Meanwhile the whole town took less than an hour.

Anyway, I’m probably done with this stuff now. It’s cool to mess around with for one evening, but no longer than that. I have respect for people who can devote years to this stuff without getting paid.
