Basic Questions and Answers Thread

Lately there have been many new threads for very simple and basic questions that tend to be answered with a small amount of posts and then fall into oblivion. This thread is for those sort of questions that are believed to be very simple and not thread worthy, and also a way to keep those kinds of questions available with the answers in one thread in case someone is experiencing the same problem, and could easily look it up. Remember to check this thread or the forum for an answer before posting.

 

I tried to put this code, (from a Sonic 1 ROM, below,) into my Sonic 2 hack, and it spat out an error about StartOfROM being $C.



SRAMSupport: dc.l $5241E020 ; change to $5241E020 to create SRAM
dc.l $200000 ; SRAM start


dc.l $20FFFF ; SRAM end



How should I get this to work?


I know I'm going about this the wrong way.

; Subroutine to perform a NEW move!!!!!!!!

Sonic_WEIRD:


btst #6,(Ctrl_1_Press).w


beq.w Sonic_WEIRD_End ; If not, branch


move.w #$3C,d0 ; set sound


jsr (PlaySound).l ; play sound


cmpi.w #1,(Ring_count).w ; does Sonic have at least 1 rings?


bcs.s Sonic_WEIRD_End ; if not, branch


subq.w #1,(Ring_count).w ; Subtract 1 rings.


ori.b #1,(Update_HUD_rings).w ; Update the HUD.


move.w #$1500,d0 ; set the speed to d0


Sonic_WEIRD_ChkDirection:


btst #0,$22(a0) ; is sonic facing left?


beq.s Sonic_WEIRD_MovePlayer ; if yes, branch


neg.w d0 ; if not, negate d0 (for jumping to the right)


Sonic_WEIRD_MovePlayer:


move.w d0,$10(a0) ; Move Sonic...


Sonic_WEIRD_End:


rts ; return


; End of function Sonic_WEIRD



This code does everything--except for moving Sonic!


Does anyone have any idea exactly why this code, inserted into Sonic 2, with the proper



Obj01_MdNormal


call does not work and how to fix it?

I think the code was meant for in-air movement, but don't know how to fix it.

 

Don't call to this from Obj01_MdNormal, try md_jump or md_air.


If that doesn't work, there might be something else wrong with the code.

 

I was just wondering if anyone could help me code the eggman monitor so it hurts sonic, I did try using the spike code but all it does is play the dieing sound


Can any one help me please??

 

You need to show us the code before we can make any logical assumptions to what you did wrong. We don't know everything Liam, a lot of us here do know quite a bit though.

 

You most likely chose hex values that aren't empty. you should open up you hex editor and check, as using hex values that are already used cause games to go haywire. At least that's what I've learned form my in's and out's with ASM.

 

No, you don't understand; I mean I want it to happen when you're on the ground.


Sorry, about any unclearness.

 

Sorry, I don't understand you. Could you clarify?

 

Check this out. Here is a simple guide on how to add this function.

 

Just tell it to jump to Obj01_Hurt. That's it.

 

{NEW QUESTION}


I was thinking about music editing, noticed Qjimbo's porter tool, and it was extremely helpful--until I noticed all the ill effects on my hack, which used a disassembly. Does anyone know of an equivalent tool that works on the disassembly files?

 

What porter tool.


Also, questions don't need a {NEW QUESTION}, it's stupid. You don't see that on Ret- oh wait.


It's bro- oh wait, it's slowly coming back.

 

Change $10 to $14, 10 is used in air, $14 is used on the floor.

 

Thanks a lot! It worked perfectly!

 

No problem.

 

Ok, I fixed the level select, but for Labyrinth Zone (The missing act from scrap brain act 3 and add final zone to scrap brain). Maybe I read the guide wrong, but I want to add sbz act 3 to labyrinth zone and add final zone to scrap brain zone so you can play through the last act of sbz. I think I made it confusing enough. Idk if this would help

Do I just use ese or do asm (Thats what I did first trying to fix the level select)

 

You will need to edit the level select text, the level select pointers and the level order. I guess these 3 functions are all included in ESE, or at least 2 of them.

 

The level order and pointers I can arrange. Then all that I have to is edit a few title cards, level text and the order. Thankyou

 

At some points the camera in GHZ 3 changes the boundary bottom. How can I edit that?
