I'm brand new to rom hacking, and I'm interested in rom hacking to create a widescreen hack for Banjo-Kazooie. Glide has a widescreen hack built in, however it doesn't work very well with BK. I've seen alot of published Widescreen hacks for several n64 games floating around on message boards and youtube, but there's hardly any info on how to create them yourself.
I realized with Banio-Tooie, that the built in Widescreen mode simply stretches the internal display on the sides, so that your television or phone could then re-stretch the picture to 16:9. This is basically what I want to do, without affecting the overlaying textures.
So, where do I start? Does anyone have experience making widescreen hacks for n64 games? Any help is appreciated! Thanks!
