(edit: moved new stuff to first post)
Following Aquaslash's suggestion, here is the topic for the hack.
A description for those new to the topic:
Sonic, Tails and Knuckles are fully functional in Sonic 2, having been backported from S3&K, and can be played at the same time.
It has the following features already:
- Powerups are shared between players.
- Tails can fly, swim and can carry either Sonic or Knuckles.
- Knuckles can glide and climb.
- Sonic can use the insta-shield.
- Lots of physics imported from S3&K.
- Lots of graphics imported from S3&K, particularly when they could be used to reduce the VRAM footprint.
- S3&K Shields have been ported, but aren't available yet in the game.
- Projectiles bounce off of Tails' tails and from Knuckles when gliding, as well as from shields, like in S3&K.
- Player 1 can swap to the AI-controlled players by pressing 'A'; player 2 can also do this, but he can only swap to the other AI. In all cases, the character must be on-screen and not being controlled by a human player.
- New HUD, done so as to free VRAM for Knuckles.
Future plans (as in: I already know about these issues and I will work on them as time allows):
- Selecting appropriate locations to place the (already fully implemented and functional) S3&K shields.
- Adding/reusing art so that Tails can carry Sonic
and Knuckles at the same time (code already exists).
- Adding code and adding/reusing art so that Knuckles can carry Sonic and/or Tails while gliding and climbing.
- Adding code so that Tails and Knuckles can tailgate behind Sonic, especially when super.
- Fixing special stages so that they work correctly.
- Fixing Sonic in the Sega screen.
- New title screen featuring the 3 characters, as well as a pre-title screen mentioning Knuckles.
- New credits, particularly for Deebs for what little I used of her Amy Rose sprite (which still looks good despite palette mangling...)
- Fix the options menu, including options to change character order and which members you want on the team.
- Remove the 2p item in the menu screen, as the 2p mode has been thoroughly removed.
- Fixing the endings, particularly in the super case.
- Making all characters available in Sky Chase,
Wing Fortress and Death Egg. An initial step has been done in the latest version.
- Support for multitap, so 3 human players can play at the same time. This will happen only after I figure out multitap protocol.
-
Sonic's AI still does not set an animation when respawning, so he uses whatever he was using when he disappeared.- ROM title needs fixing; I didn't fix it yet because it is minor, unimportant and trivial to fix.
- Knuckles has issues climbing on surfaces.
- Editing the demos. This is the second-to-last thing I will do on this list (the last being fixing the ROM title).
The following bugs from the
previousfirst version have been fixed:
- Instashield during the act clear screen messes up the letters.
- Dying and respawning breaks it in a whole crazy way.
- Music doesn't return after getting an Extra Life.
- Weird crash with Knuckles (hopefully) fixed.
- Portraits messed-up in Sky Chase, Wing Fortress and Death Egg.
- Super portraits for Knuckles and Tails were missing.
- The player mode variable was miss-behaving.
- Balriky had wrong colors.
- Knuckles' lower jump height makes his following the other duo a lot more difficult. (AI does not have a lower jump).
- AI follows player much more closely now.
Things to look out for:
- There may be some remaining palette issues. While I did a good job of hunting them down, one or another may have slipped.
- Badniks you can't interact with. I don't think there are any -- but to minimize lag, I switched to a S3&K-style collision list instead of checking for collisions with every object. This requires me to add code to add them to the list.
Without further addo, here is
revision 0.02.
