From b0cb7a159d36c486b351df277b3c3b6613f17757 Mon Sep 17 00:00:00 2001 From: Tauwasser Date: Sun, 3 Jun 2018 04:09:36 +0200 Subject: gfx: re-organize some graphics and disassemble gfx load code All graphics were split so that proper labels could be placed. Font was not split, because that was nicely handled using the charmap constants. If proper lengths should also be handled using automatic calculation using labels, some graphics would need further splitting up in order to place labels.s Signed-off-by: Tauwasser --- engine/gfx.asm | 139 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 139 insertions(+) create mode 100644 engine/gfx.asm (limited to 'engine') diff --git a/engine/gfx.asm b/engine/gfx.asm new file mode 100644 index 0000000..2c19fe6 --- /dev/null +++ b/engine/gfx.asm @@ -0,0 +1,139 @@ +INCLUDE "constants.asm" + +SECTION "Misc GFX Loading Functions", ROMX[$4000], BANK[$3E] + +LoadFontGraphics:: ;
