Homebrew How to get Sonic 3 & Knuckles to work on jEnesisDS

[RocketRobz]

As the original S3K rom is 4MB, jEnesisDS has the limit of running <= 3MB roms.

To get it to work on jEnesisDS, download the below patch:

Sonic 3 K + Save Fix / Apply to a Clean - Sonic And Knuckles & Sonic 3 (JUE) [!]

CRC32: 63522553
MD5: C5B1C655C19F462ADE0AC4E17A844D10

Click the underlined username for more information, such as how to apply the patch.

This patch puts all the Sonic 3 stuff excluding the Competition/2 Player stuff in the rom.
As the Competition/2 Player stuff are excluded, selecting Competition in the title screen
will take you to the Blue Spheres Game ("NO WAY! NO WAY! NO WAY?" press A+B+C).
The SRAM doesn't work, so you have to use Save States. This is a jEnesisDS problem.

Enjoy playing Sonic 3 & Knuckles on jEnesisDS!

Or you could just get the Sonic Classics Collection for DS and have all the old-school Sonic's (sans Sonic CD) in one package without any hassles. It's already optimized for DS/DSi and made by the same dude who made the jEnesisDS emulator, but all official and stuff.

I know about that. Sonic Classic Collection isn't 60fps, jEnesisDS runs at 60fps.
Imagine how a 4MB rom can run on 4MB RAM...

so the guy who made the emulator got hired? and ended up working on the ds game?
if so, cool well done for him!

 

[Chary]

Hey, this is cool. Thanx man!

The SRAM doesn't work, so you have to use Save States.

Could you clarify on this matter? Because I played to Hydrocity as Tails on Kega Fusion and the SRAM is fine (so far). Is it a jEnesisDS problem, using too many save files, what?

 

[Dann Woolf]

Doesn't Sonic Classic Collection run better on a DSi/3DS?

sort-of. he got officially release a hacked version designed to just run the sonic games. as a result, he was unable to continue updating jenesisds.

oh that is awesome, and interesting that the company chose to go that route... i'm surprised, but i guess it makes sense ha

Is there a patch that changes the resolution of a Genesis game, so that it is compatible with the DS ?

 

[Deleted-236924]

How well does Sonic Classic Collection run on a DSi/3DS?

 

[RocketRobz]

Is there a patch that changes the resolution of a Genesis game, so that it is compatible with the DS ?

No. The Genesis resolution is always 320x224 (or 256x224 with some games).
You can turn off Vertical Scaling in jEnesisDS. You can do that by touching the controller icon, then go to vertical scaling.

Thanks! Will do.

Sorry to necro this, I'm aware this thread is over two years old but I thought it best to post this here because this thread appears top of the list when searching for how to get Sonic 3 & Knuckles working in JenesisDS so I felt it best for everybody to post it here rather than create a new thread for no reason.

I hope the OP doesn't mind, but I uploaded the .ips patch to other places just in case the above link every dies. I think the OP is no longer active here so it would be a shame to lose the patch in this way.

If anybody could upload it to somewhere more permenent, it would be appreciated!

Well? What can I say? You are a god among users/rom patchers. You saved my day. Thanks a lot Robz for reuploading the file!

Yeah I know, a bit necro.
Guilty! I'm still using my DS Lite, and the official Sonic Collection's S3K still lags LIKE HELL. Plus not being able to deactivate vertical scaling makes it look awkward.

Well, talking about necro..... Is there a way to run JenesisDS from the DSi SD card using sudokuhax and HBMenu? Cant make it recognize the roms, do I need a .cfg file ?

You can try it with SRLoader.

Playing around with this a bit - hex edited the header of a patched Sonic 3 Complete rom into this patch and now saving is working (renamed header to Sonic 3 Knuckles)

So if you want sram working apply this patch SECONDLY after patching with sonic3k.ips just changes the header so jEnesisDS uses the save function properly!!

Needs testing for saving in Sonic & Knuckles part of game.

Also if you can’t get saving working with games such as Shining Force series etc use v0.7

https://filetrip.net/nds-downloads/...isds-v0-7-apprenticeminusds-v0-2-6-f2056.html

Load the game twice and save both times then the save file it creates will be compatible with v0.7.4

P.S. This save patch works with 0.7.4 seems it’s only games that use large saves

EDIT: Still has graphical glitches in slot 5 and beyond of level select screen this is emulator related though these slots still work
