Oh no, have some very experimental spoilers: Hello, spoilers. How are you today? Another spoiler, just for demonstration. Neat tricks (vanilla)Vanilla 1UP point checkpoints:Super Mario World has four 1UP checkpoints objects. They don't appear if you already collected them all in a level (even if you die), so they can be used for checkpointing. Essentially, you can hide blocks (for instance warp pipes) by putting 1UP checkpoints over those. Then, when time comes you can guarantee getting 1UP checkpoint (by putting multiple 1UP checkpoints in a row). Display Level Message 2: Put two Display Level Message 1 sprites in the same place. Inverse switch palace blocks: To be written, but I somehow managed to do that in vanilla (hint: bottom tiles of palace switches are solid, the object doesn't appear when switch is already pressed, so you can put something below it). Neat tricks (ASM)Hardware registers:http://problemkaputt.de/fullsnes.htm Disable statusbar IRQ: Code LDA #$01 STA $0D9B JSL to subroutine ending with RTS (credit: I don't know, possibly Alcaro): This code works by pushing five bytes on stack (bank, return address, address of byte 6B (RTL) minus 1 (to handle PC implicitly changing) in a given bank. Then it jumps to RTS function, which uses RTS opcode to move PC to RTL opcode, which returns to a provided location Code PHK PEA.w .ret-1 PEA.w $varies JML $subroutineaddress .ret varies table depending on bank (fast ROM banks are identical, so change 8X into 0X): 00 - $84CE 01 - $80C9 02 - $B888 03 - $827E 04 - $8574 05 - $8124 07 - $FC50 0C - $9398 0D - $A104 7X - write RTL somewhere or modify your function to end with RTL |
