My tentative FF4 Prettified hack in motion: https://www.youtube.com/watch?v=o6lEC8zBP-Q
For those who have no idea what I did in this hack, here's an explanation: the proportional font is all predrawn, which means the VWF effect is generated in advance and then stored in the rom. Some things, like item names, are dynamically copied in real time via DMA, while others are static sets of 256 tiles (menu static messages, in other words) switched around depending on the menu section.
The thing about this hack is that I wanted to check how fast this could run on the SNES. Turns out byuu was correct in one of his articles: it's fast and looks good. I also tried a few slick tricks like "expanding" RAM by using the SRAM as a scratchpad (I'm currently using 32KB because I needed a huge temp buffer for preserving some VRAM data). I was even surprised by the DMA working correctly from/to SRAM!
Hopefully more people will try this approach. It's fun to implement and it works great even with FF4, which has some really naaasty
