But instead of just adding Sonic & Knuckles as a separate game, I would prefer to replace Sonic 3 with Sonic 3&K or Sonic 3 Complete. Otherwise, I would have to edit the menu to fit the fourth game and modify S&K ROM to make it work separately, which is really hard and exhausting work.

Also, I think S3&K/S3C would be more interesting to play. =)

I'd prefer the actual S3&K ROM over a fan-made Sonic 3 combination. If people say that S3K counts as one game, then it should be the case in this collection.

[Covarr]

Really cool so far, though I'm personally more excited for Sonic and Knuckles' addition. Sonic 3 alone just doesn't give the same warm, fuzzy feeling. :D

Actually, I'm wondering about something: Can't you put EVERY MegaDrive Sonic game ever created in the ROM? I mean sure, it won't work on many systems, but having the original line up, including the S&K lock-ons, plus S3D and Spinball would be supah dooper ameizink!

Sonic 2:
- EHZ deformation bug fixed
- Air Speed Cap removed

Can you also fix the Super Sonic glitch when he gets stuck in the air after the sign post but also can you add the ability to enable Super Sonic by double jumping?

What I'd really like to see is the games homogenized in terms of style. It wouldn't even have to be full graphical overhauls, but making the characters sprites the same across all 3-4 games, remixing Sonic 1 and 2's music using Sonic 3K instruments, using one style of title cards, HUD, monitor styles and such. I can't imagine it being very hard, and it is the little things that count most sometimes.

Looking forward to seeing what this project's revisions will bring to the table. You impress as always.

Im sure he can, but exceding the 4mb limit is a bad idea. It would not even work on emulators, someone would have to modify these to allow that much data.

[Rika Chou]

This is pretty neat.

Is there any way to return to the game select menu after you already stared a game?

Since most ppl don't own flashcards or eeproms or whatever, they will be playing this on emulators.
Fusion is the only great emulator by today's standards but modifying is not possible because it's not open source.
I really don't want to have to get old Gens out of the closet again to play a hack. Better to stay under that limit then.

This is kinda what I'm doing already, starting with Sonic 2. It's a great idea!

Mhm, godspeed. I'll look forward to seeing what you can pull off. I know another member here was working on a "S3 Edition" of Sonic 2, but I don't know how far he got with it.

If he can make it perform Super Street Fighter II style bank switching inside 5 megabytes and make it work on my Everdrive, he's got my vote.

Even if it won't end up working on emulators, that would precisely give the emu authors a reason to upgrade them, so it's a win-win situation.

[The Growler]

Isn't there any way to "patch" it to increase the max MB size like Nintendo fans did with Lunar IPS?

[Andlabs]

The Mega Drive memory map only gives you 4MB for cartridge space. You can go up to 10MB before hitting the Z80 memory access area (and thus the start of the system registers, which are followed by RAM and its mirrors), but if you have a Sega CD connected, you lose everything between 4MB and 8MB, and if you have a 32X, everything between 8MB and 10MB (or I think; not sure).

Most, if not all, emulators hardcode the SSFII mapper to only work with SSFII.

One possible idea is to just make all three games run on the same base code (I think they already all use the same sound driver; not entirely sure) — all three games will use the same engine and what not. IDK how well this will work out for S3K's level system, but :/

Small suggestions:

• The logo would look even cooler if, before it started spinning, Sonic would appear and run through it.
  
• Add the compilation's title on top of the "Game select" text.
  
• Original music?
  
• I think you should remove the "A - Play" message, as everybody is going to press Start anyway...

1. I had this idea, but refused it because I don't know how to perform such a scene. If Sonic would run quickly from left to right (like in Sonic 2), the logo spinning vertically after his touch would look strange. It would be obviously better to make it spin just like a signpost, but the hardware isn't capable to do it even using VDP-tricks, I would have either to render it by software (like I do in menu, but I hardly find enough resources for that) or keep each spinning frame pre-rendered in the ROM (which will take too much ROM space). Another way I imagine this scene is Sonic falls from the top and touches the logo, then he lands and runs away. But again, I have no idea how to perform it gracefully.

2. Nice idea, I might try it. Or make a separate screen with project's logo. The name doesn't make much sense here though, it's a compilation, not an original game/hack. Also, I'm likely to change its title when I include more games there.

3. Do you mean the new music composed specially for this project? Well, I don't think if I need this, in fact I'm rather content with the current music, which Jet ported for me. I may replace it with more suitable ports if I find ones.

4. "C - Credits" will stay absolutely alone then =( An extra button to launch a game isn't odd or confusing to my mind.

Wiki'd!

Nice article, thank you! =)

Just a small note: you wrote "Sonic 3 in 1 is a compilation hack" there. My project isn't really a hack (this is the reason I call it a 'project' =P). It's more like a MD-program from the ground up, including three hacked Sonic games and a small engine to run them. Or I just understood the phrase "compilation hack" wrongly. My English is weak, you know.

I will have troubles with adding them. Not all the games have their disassemblies, this makes adding them really difficult. I'll have to fix every JMP/JSR offsets, (xxx).w and (xxx).l addressing modes, DMA-transfers from ROM, and besides that, there are loads of special cases which are hard to recognize.
I may attempt to do it to practice in HEX-hacking, but chances I fully success are low.

Yep, I plan use SSF2 bank switching. Thanks to Sik who provided me info on it earlier, I know how to work with it.
If I cut the paddings of the games, it will be possible to fit it in 5 Megabytes I think.
