ThomasSpeedrunner Help Thread

If there's over five pages, perhaps I should split all this into another thread.

 

Not necessarily. Three major differences here:

1. - The spindash allows for multiple charges, while the Super Peel-Out can only be charged once.
2. - The spindash shoots Sonic off in a rolling state, while the Super Peel-Out shoots Sonic off in a super-fast running state.
3. - The spindash's animation is in the Sonic 2 disassembly by default, while the Super Peel-Out does not have any disassembly assigned to it because there are no disassemblies of Sonic CD.

How do I overcome these problems?

1. You can still modify the code that allows you to rev up the spindash, that way it can behave exactly like the Super Peel-Out.

2. You can also modify the code that sets him in his rolling state to his running state.

3. Finally there are a few sprite sheets of Sonic from Sonic CD that you could grab from various sites and you can rip the few sprites that are used for his Peel-out animation. You don't need a Disassembly of Sonic CD for this at all. (Plus like Super Egg said, there isn't one.) While I know this is an older post I hope this helps a bit. Though I highly suggest that you start small to get a better understanding of how the 16 bit games work, and learn 68k asm. While that will take a while it's really worth it in the long run if you love to hack the genesis games. Plus this way you'll be doing the work instead of someone else doing it. (Sorry if I sound rude, i'm not being mean i'm just telling you to help you in the long run. Plus I think it's more rewarding when you code something by yourself.) I know you want to dream big and make a really awesome huge hack with tons of characters, but if you don't understand any pieces of code used in any of the 3 main Sonic games then you're not ready yet. Start by editing Sonic's and Tails' top speed and go on from there. Plus you also want Tails to fly right? Grab the S3K disassembly, and find his flying code then do your best to port it. But I highly recommend that you wait to try and port his flying code once you learn some 68k asm. Good luck with your hack.

I think that last one makes sense, but I'm not sure. Anyway, I think I might toy around with the Spindash code and see what I can accomplish. Expect results soon.

 

I think I'm on the right track with this. It's not done yet, but I think I'm getting closer.

I think I'm on the right track. It's a modified version of the Spindash code. Not perfect (or even complete, for that matter), but it works. Still experimenting with different combinations of code, so expect results eventually, but, the verdict:

Usable? Check.

Buggy? Check.

Complete? fuck NO.

 

The "Super Peel-Out" I'm working on (and until I've tried everything I possibly can and given up, I don't want help with it) now only has one charge. It's not very much progress, but it now has two things in common with the true Super Peel-Out:

1. Both only have one charge (although the one I'm working on can be recharged just for the heck of it).

2. Both send you shooting off at super-high speeds in a running state when released.

I'm still working on it, but I think I'm getting closer.

 

 Sonic 2 Recreation?

 

I've decided to start experimenting with the homing attack as well, since Tails' flight is already ripe for the taking (although that won't be for a while). Here's what I have so far:

Code:

Sonic_CheckHomingAttack:


        cmpi.b  #1,jumping(a0)  ; is Sonic jumping?

        beq.s   +               ; if so, branch

        bra.s   return_1AD95    ; otherwise, return

+


        move.b  (Ctrl_1_Press_Logical).w,d0

        andi.b  #button_B_mask|button_C_mask,d0 ; is B or C pressed?

        bne.s   +               ; if so, branch

        bra.w   return_1AD95    ; otherwise, return

+

        move.w  #$700,x_vel(a0)  ; immediately set Sonic's x_vel to $10

        move.b  #2,anim(a0)     ; use "jumping" animation

        move.w  #SndID_SpindashRelease,d0       ; play the spindash release sound (or at least until I can get a sound for the jumpdash/homing attack)

 

return_1AD95:

        rts

If there's anything I can improve, let me know (I'm not necessarily asking for help here, just for suggestions).

 

EDIT 1: Added "Ctrl_1_Press_Logical" line and changed $10 to $30 for x_vel.

 

EDIT 2: Changed this bit:




        tst.b   jumping(a0)     ; is Sonic jumping?

        beq.s   return_1AD95    ; if not, return





to this:




        cmpi.b  #1,jumping(a0)  ; is Sonic jumping?

        beq.s   +               ; if so, branch

        bra.s   return_1AD95    ; otherwise, return

+




and changed x_vel to $700.

Ah, the old days... much improved since then =)

Plus, I only just realised this topic.  Where the fuck did this appear from?

Dude, think about it. Clues:

a) My display name.

b) The title of this topic.

c) The large (and looking back on it, insane) amount of questions I've asked since I got here (I'm trying not to ask as many questions now, and I am experimenting with the Super Peel-Out and homing attack as we speak).

I'll give you the answer in thirty minutes if you don't figure it out by then.

 

Remember those posts that got removed from the Q&A thread that made that other guy look like he was triple posting?

From the looks and screenshots, S2Recreation has went all the way up.

 

Okey dokey...looks like I'm unable to port the Sonic 1 sound driver to my hack because my s2.constants.asm file doesn't want to play ball. It's something with the master playlist and all that annoying, super time-consuming stuff, so I figured, "You know what? I'm doing this later, when I actually have some damn free time on my hands." So yeah. It will be ported, though, and I've decided to try to, in terms of level design, do something fairly similar to Sonic Megamix. You'd be surprised at the amount of inspiration that comes from that one hack alone.

As for the Homing Attack and Super Peel-Out, I'm still working on those. It may take me some time, plus I'm still revamping the already done level layouts and coming up with new ones, but while you're waiting for the official release, have a look at this video, showcasing the new Corrosion Plant Zone Act 1:

http://www.mediafire.com/?fay2qoq455p7827

Please tell me what you think of the layout and/or how I could improve upon it in any way. More rings (can't blame ya for that ), more enemies, more gimmicks, whatever. Just as long as it's something that could be improved.

 

I don't think people are going to want to download such a large video, upload it to youtube or something. 

 

Youtube's being a bit of a jerk at the moment when it comes to uploading videos, so for the time being, I have to give them to the community in raw .avi format.

 

Don't get cocky with me, mate.

Youtube's being a bit of a jerk at the moment when it comes to uploading videos, so for the time being, I have to give them to the community in raw .avi format.

I highly doubt anyone will want to download a RAW AVI format. What's wrong with youtube? Seems fine with me.

Apparently, it can't play ball with .avt files. 'Nuff said.

 

Maybe the file is too big in itself. Try downloading a converter to convert it into a different format at a smaller bitrate. MP4 or MPEG is a good choice, and YouTube should be fine with that.

 

The problem isn't that your video is AVI, I used to record AVIs with Gens Rerecording and upload them to YouTube, but you're using Fusion right? Fusion uses its own codec for videos, which YouTube doesn't have a decoder for. So you have to change them to a format YouTube understands. Personally I use VirtualDubMod and x264vfw for video compression.

 

The thread was split by myself because it mostly was ThomasSpeedrunner posting all the time asking for help.

 

Well, Spanner, I personally don't mind this thread being here (because now at least other people aren't bothered by my question-asking), but I can assure you I'm trying not to ask as many questions as I experiment with some of Sonic's abilities. You know, so I can see what works and what doesn't.
