my disassembly
im sorry if i write too much

 

I found a weird SMPS pack called Cool-Spot's smps archive with some stolen content, but obviously i wont use the stolen content, There a bunch of songs that i saw people using on other hacks like Angel island Act 2, and others And a bunch of sonic 2 music and sfx in a folder called "From Sonic 2 Clone Driver" Inside of a folder called Sonic 2 to Sonic 1, is there any problem to use it?

The glitch sound might be because you added too much data

 

Wait what?

Better dont use them, that's what I recommend, but… if you want to use them, its at your own risk.

 

Ok then, Cool-Spot was a russian person who stealed stuff from Megamix, and OuricoDoido got it some of the codes and putted it on the infamous hack STHOSP, But i gonna use the music from STHOSP since it's no stolen, thanks for the help

 

Hey there! I'm new here, working on my first hack, and i'm thinking of making custom music for it; but, i can't find any software to do it.

If it helps, it's a Sonic 1 hack, Github dissasembly.

Help is highly appreciated! Thank you!

 

hmm... Im not an expert in smps work but if you want to add custom music you can use Mid2smps, smps2asm and vgm2smps.

 

Thank you! I'll try that!

Heya, i'm on Mid2smps, and i keep getting this error:
View attachment 6815

I'm following this tutorial, if it helps.

Nevermind-- The issue's fixed! Sorry for the inconvenience!

 

yes i use other sonic 1 disassembly and sound glich was gone but im stuck in add dma queue now
i want to know how fix dmaqueue

 

Mind if I ask, what exactly are you planning? Do you want custom music or do you want to convert another track, or maybe even a game's music port? Not really too many options in regards to tools, in all honesty, but you can still make summat work.

 

its custom music, specifically, to recreate a track from sonic 4.

 

I've been racking my brains all day because I can't port the Sonic 2/S3K invincibility stars to RetroKoH's S1Fixed. I actually made it in normal Sonic 1, but in S1Fixed... ugh... Well, the sprites get invisible...
I know it happens because the invincibility stars and the shields were already separated and uncompressed. But the stars are different still uses shield mappings. And I don't know which code makes it don't work

Just, look at this:

Spoiler: Sonic 1 (in Sonic 2 style; test hack)

Spoiler: Sonic 1 (in Sonic 3 style; test hack)

Spoiler: S1Fixed)

The first two worked, but the last didn't.

 

In S1Fixed, the invincibility stars object is 21.

This is the code I used. I don't remember from where I got these. But I did the changes and still didn't worked. :[

I converted the original mappings from Sonic 2 to ASM, and...

Spoiler

Yeah... It glitched the background.

But if you want to know how the stars are loaded, well, there it is

Code:

Pow_Invinc:
    if SuperMod=1
        btst    #sta2ndSuper,(v_player+obStatus2nd).w    ; is Sonic super?
        bne.s    .nomusic                                ; if yes, branch
    endif

        bset    #sta2ndInvinc,(v_player+obStatus2nd).w    ; make Sonic invincible
        move.b    #$96,(v_player+obInvinc).w                ; time limit for the power-up -- RetroKoH Sonic SST Compaction
        move.b    #id_StarsItem,(v_starsobj).w            ; load stars object
        move.b    #1,(v_starsobj+obAnim).w
        tst.b    (f_lockscreen).w                        ; is boss mode on?
        bne.s    .nomusic                                ; if yes, branch
        cmpi.b    #$C,(v_air).w
        bls.s    .nomusic
        move.w    #mus_Invincible,d0
        move.b    d0,(v_lastbgmplayed).w                    ; store last played music
        jmp        (PlaySound).w                            ; play invincibility music

 

After longs days, I finally fixed my problem. And It was actually my fault. Hahahaha! And also, I changed the original value, "$A820", to "$AA20". And now, it's finally working. Thanks for helping me, Delta!

 

i dont know what happened, but in the results the colors are wrong (the hud is using the yellow colors of the second palette)

 

that's a mappings issue

 

oh... in that case how i can fix that?
