This is the ROM map for Boktai 3 (J).

Address Description
0x80001f0 undefined IRQ_Dispatcher(void)

Copied to IWRAM @ 0x3003a60 during boot, and executed from there

0x8000350 int Video_UpdateSpritePalette(Sprite * param_1, undefined4 * param_2)

Copied to and executed from IWRAM @ 0x03000000. Sprite rendering related.

0x8000430 undefined Video_RenderSprite(Sprite * param_1, undefined4 param_2, undefined4 param_3, undefined4 param_4)

Copied to and executed from IWRAM @ 0x030000e0 (more functions like this follow). Renders one sprite.

0x8000e90 undefined Video_RenderAllSpritesImpl(void)
