Persona 3 Dual

• I made the top screen fade via bg opacity (not brightness)
• I plan to try to add another bg image on top
  • Might need to use extended palettes?
  • Use sprites? (treat moon as sprite?)
• Created GitHub repo + git branch and pushed
• I got the moons to show up as sprites
  • Sprites can be max 64x64 (I chose 32x32 for demo reasons)
• I learned that what I want is to use extended palettes (there is an example with 2 background images)
• I got 2 background images up
  • Instead of a moon, I put the room shadow instead. It looks really cool
  • For the moon, I might just bake it in directly to the sky texture
• There is a problem when displaying background images. The 2nd image kind of corrupts halfway through, then fixes itself
  • It’s a VRAM issue, if we mess with:

  bgInit(0, BgType_Text8bpp, BgSize_T_256x256, 28, 0);

  the last 2 values (28, 0), then it can render properly

• Fixed corruption problem by using https://mtheall.com/vram.html to check how/where to place in VRAM
  • Need to click into the header files of each image to find the tile #

• I need to fix both the sky and room images
  • I cropped them a bit weird, transparent in weird places
  • Need to bake in the moon image
• I want to see what the Persona 3 home screen looks like and try to mimic it

• The person slides in, the moon slides in, then there is a Tartarus image rotating (like a clock) in/out of frame
  • I will bake in the moon
  • I want to slide in the person
  • I want to add logo on bottom screen (sprite?) w/ “Press any button” (normal) text
  • We might cut the rotating Tartarus image (sprite?) (though doable) due to memory constraints
• Once I get a rough home screen setup, I also want to figure out how to play music
