Basic Questions & Answers thread

Right, that. BTST could have been used in this case.

 

I am still having trouble getting SonicED1 to load my save states properly. It keeps claiming the files are corrupted.

I will eventually work out why these Sonic 1 originals I keep loading turn out to be completely useless with my system. However, does it matter what emulator you use to save the game in the first place?

I am using Kega Fusion and it is struggling to even open Sonic 1 originals themsleves. With hacks it is completely fine.



Also- after using the save state of a hack I managed to open the actual Editor screen for SonicED, just to try messing about and practising until I gain some basic footing.

But I find the control system perplexing. Is there any other tools I'm suppossed to be using? Draw Mode...Select Mode. It seems I'm just using these to erase bits of background. And by highlighting certain pallette boxes I've so far only succeeded in making the backgrounds of certain tiles become highly distorted.


So to sum up. Two questions:

1- Is my current emulator the reason why my Sonic 1 ROM refuses to load properly?

2- Can someone give me a basic rundown of SonicED's control system?

 

First off, it's SonED, not SonicED. If you have trouble using SonED, read the Readme file. You may also want to try SonED2, which doesn't require savestates, but instead requires a split disassembly (get one here: Disassemblies). If you split and build right away and don't get a working ROM, then you're not using a clean Sonic 1 ROM; search again.

 

All of the ReadMe Files are empty. I opened them up and my notepad just came up with a blank page.


However, I will explore SonEd2. If it doesn't use save states it will be easier.

Thanks for the advise.

 

There is stupid question, but I hope I get answer.

Only thing what I can do, is art somewhat, but now im trying to learn something.

How I can make object hurt sonic?
If sonic break eggman monitor, how can I make it hurt Sonic.

Code (Text):

1. Obj2E_ChkEggman:    ; XREF: Obj2E_Move
2.         addq.b  #2,$24(a0)
3.         move.w  #29,$1E(a0)
4.         move.b  $1C(a0),d0
5.         cmpi.b  #1,d0; does monitor contain Eggman?
6.         bne.s   Obj2E_ChkSonic
7.         rts ; Eggman monitor does nothing

Do I need to replace that last text whit something?
Im totally newb whit this.

Or is it that simple?

 

Code (Text):

1. Obj2E_ChkEggman:    ; XREF: Obj2E_Move
2.         addq.b  #2,$24(a0)
3.         move.w  #29,$1E(a0)
4.         move.b  $1C(a0),d0
5.         cmpi.b  #1,d0; does monitor contain Eggman?
6.         bne.s   Obj2E_ChkSonic
7.         move.l  a0,a1
8.         move.l  a0,-(sp)
9.         lea ($FFFFD000).w,a0
10.         jsr Touch_ChkHurt
11.         move.l  (sp)+,a0
12.         rts

In this way, the Eggman monitor will hurt Sonic in the same way a badnik would: if you have a shield, you'll lose the shield; if you are invincible, you won't be hurt; if you have rings, you'll lose them; if you have no rings, you'll die.

 

Oh, and I just testing and learning, so how I can do this.

If I kill buzz bomber, I got hurt.

 

Try this:

Code (ASM):

1. Obj2E_ChkEggman:            ; XREF: Obj2E_Move
2.         addq.b  #2,$24(a0)
3.         move.w  #29,$1E(a0)
4.         move.b  $1C(a0),d0
5.         cmpi.b  #1,d0       ; does monitor contain Eggman?
6.         bne.s   Obj2E_ChkXXXX
7.         tst.b   ($FFFFFE2D).w   ; is Sonic invincible?
8.         bne.s   ChkEggmanNO ; if yes, branch
9.         tst.w   ($FFFFD030).w   ; is Sonic invulnerable?
10.         bne.s   ChkEggmanNO ; if yes, branch
11.         lea ($FFFFD000).w,a0
12.         jsr HurtSonic
13.  
14. ChkEggmanNO:
15.         rts

Change XXXX to the name of the monitor after this code.

 

Thanx guys, now I understand some stuff.

 

Almost forgot:

Thank you FraGag and Malevolence for your help!

Now I can add some intresting ideas to my hack!

 

How do you convert 256x256 mappings to 128x128 mappings?

 

I'm not sure if this is possible. There are a lot of 128x128 possible chunks that could be made from a 256x256 chunk (if you're referring to this).
But even if this is not the case, I don't think there is a program which can do this automatically.

 

I once made a custom 256 to 128 converter for someone, so yeah, the conversion is definitely possible. If all else fails, PM me and I'll give it to you.

 

There's uhh..you know SonED 2? <_<

 

I'm working on adding the Sonic 2 level select menu to Hives Sonic 1 disassembly.
Since Esrael's files/guide only covered Drx's disassembly I've been going mainly on guess work.
I've managed to get the rom to build and go to the level select screen, but I have to press start again (after pressing A+Start) to get it to appear, and it's using the default Sonic 1 level select pallet, somthing I assumed Esrael's files/guide would fix automaticly.

Furthermore it woun't let me move Up/Down between the levels on the LS screen. Despite this minor setback and the pallet problem I'm very happy that I managed to do somthing that is (to my Knowledge) not documented for Hive's disassembly (but if it is I couldn't find it).

That said, I would greatly appreciate any help in fixing these two problems.

 

Every time I try to build my dissassembly into a .bin file, its gives me this 1KB shit. (s1comb.asm is there too.) Can anyone help?

 

What is the output of build.bat? Generally, the reason for not being built properly is displayed. If you simply run build.bat then you need to either run it from a command prompt or edit build.bat to add pause to the bottom. Once you have done either of those things, whatever errors are occurring will show up and you can post those here for help.

 

Ok guys, I don't know if this is the right place to post this type of question but here it goes anyway: Do you guys know any simple way of changing the sonic sprites on the genesis games? I wanted to do that because I really like sonic1 /sonic cd sprites, and I wanted to use them on sonic3&knuckles. Could anyone help me with this?

Thats what came up. I don't understand why it says cannot find include file. I haven't deleted anything or added anything at all.
