Oh no.


I died on the Chemical Plant boss (It's been years, my skills are rusty), and when I came back, I couldn't go on that loop - the left side's collision must have gone wonky. It may have been caused by Knuckles, because I switched to him before trying to run up the loop.

Doesn't appear to be in the bug list.
-Collision errors?

EDIT: Sonic and Knuckles couldn't seem to go through the loop, but I switched to Tails and he did it fine after I flew around and collided with some stuff, albeit with some layering issues - he went behind the loop instead of in front of it, Layer wise.

EDITKING: Strangely, the Speed Shoes don't seem to slow the music down in Aquatic Ruin zone.
EDIT AGAEN: The Pinball flippers and launchers don't seem to work unless everyone is present. Wait, never mind - sometimes they just don't work.

This is the most fun/awesome hack I've played in a while! I'll see if I can record and upload a video of the gameplay at lunch.

Amazing! Nice work!

The hack freezes in Regen at Emerald Hill Act 1 title card.

Out of curiosity: were you playing as Tails when you crossed the checkpoint?

EDITKING: Strangely, the Speed Shoes don't seem to slow the music down in Aquatic Ruin zone.

Uff, I finally found what was causing this: the fact that I removed the 2p music. Strangely, I only had to add dummy music IDs for them to the list and it started working again.

EDIT AGAEN: The Pinball flippers and launchers don't seem to work unless everyone is present. Wait, never mind - sometimes they just don't work.

Thanks for the report. I found out what was causing it and fixed a slew of similar problems waiting to happen.

I will release a new revision after fixing the layer bug and get Tails and Knuckles working on Sky Chase and Wing Fortress.

Edit:

I will investigate, but it is probably due to some missing 'even' directive somewhere. I have been diligent in adding them, but may have missed a few spots...

I've never uploaded a video to YouTube before so hopefully I've done it right :p

EDIT: Btw you can see the reported collision bug at 1:08

I'm eating this up. The novelty of it is amazing.

Something I noticed, Knuckles edge animation starts normally but then he uses his looking up animation. Nothing major, but figured I'd point it out.

Keep it up, man. This is great.

Edit: Other things I noticed:
- No count down while under water. I've been underwater with no shield for about.. 2 minutes now. Not had one bubble. I'm wondering if Knuckles or Tails has a shield and that's playing into it, but that brings me to the other thing
- The AI characters don't return to you underwater. I had this problem in both Chemical Plant and now Aquatic Ruins.
- In Casino Night, I'm getting nothing but Triple Robotniks in the slots. Well, once I got a jackpot and 2 robotniks, but still.

It's funny in a way how when somebody was working on one hack, another person fires back with a similar modification. I'm enjoying this hack and even though there are bugs to be fixed, it's awesome how you managed to get enough VRAM space to cater for all three characters.

Interesting how you managed to learn a lot from hacking Sonic 2 in a matter of weeks, most people take months, even years to get to a standard like this. I'll be watching this hack and any other projects you work on in the future.

I'm having fun attempting to keep Knuckles following me while avoiding Tails.

[SonarDragon]

I don't think Sonic and Knuckles are meant to hump the air when being carried by Tails... Try slowing down the 'hanging' animations.

Edit: Hilarious, Knuckles hit a speed shoe monitor while Sonic was active, and it slowed the music down to half, but the speed was upped anyway. I kinda like that, you're going to fast so the music feels slow. Okay, that's stupid.

I'm having alot of fun with this!
There's an issue with the Mystic Cave vines, though. Sometimes you can't jump off, for whatever reason.
Anyway, I need to kill about 8 minutes until the time runs out and I can move again.

Yeah, you can't jump off when playing as Tails or Knuckles. Tails can't jump off the vines in normal Sonic 2 when playing as Sonic and Tails either, and I think it's related.

I found a lot of trouble in casino night zone. Sometimes the pinball launchers (both the red and the white ones) don't work. I think its gotta do with the controller, the genesis cant handle 3 controllers at the same time.

[RGamer2009]

I know this seems pointless and its probably just me, but I feel that when playing the newest build...

The CPUs feel like robots. Even more so then the first build.

They follow my every move to a tee, and stay RIGHT next to me. No breathing room. When I stop...they OVERLAP me perfectly. They move so quick to my movements that it doesn't seem like they are themselves.

Maybe keep Tails at half his normal distance, and make Knuckles have Tails normal distance from Sonic. That would at least give them less of a robot-feel, and not have them be right next to me.

I played up to Wing Fortress Zone. I love the addition in Sky Chase Zone

Anywho, bugs. I didn't have any game breaking bugs until the end - in Wing Fortress Zone, Sonic seems to have problems interacting with the silver blocks that blow off the wall. Eventually this threw me into a wall and Sonic was stuck walking.

Overall though, I absolutely love it, and can't wait to see future revisions.

[flamewing]

New revision is up. changes and link in the first post. Old savestates will not work.

It is indeed a but inherited from the Sonic 2 code. Basically, they checked the real controller input for Sonic and 1p Tails, and the logical controller input for 2p Tails. The problem was that the vine sets object control flag, hence the logical controller never gets set to the real input. I fixed it by reading the real input for human players and the logical input for CPU players.

Edit: Funny, two bugs reported while I was typing the post saying that they were fixed :-)

Nope, it was because I was forgetting to clear a register before reading a byte into it (I needed the register to be used as a word, but reading from a byte).

Anywho, bugs. I didn't have any game breaking bugs until the end - in Wing Fortress Zone, Sonic seems to have problems interacting with the silver blocks that blow off the wall. Eventually this threw me into a wall and Sonic was stuck walking.

The new revision fixes this.
