Sonic 1 and 2 ported to 68k

[mc68060]

Apparently someone has ported Sonic 1 and 2 to 68k but only for Vampire Amigas. See here: https://artishq.wordpress.com/2021/0...amped-12-pack/

Looks like this was ported from the Android version. So how did he do it? Decompile the Java bytecode of the Android version of Sonic and port that Java code to C to compile it for 68k? Looks like a lot of work to me!

Sonic is literally already in 68k? It was coded on the megadrive.

I think this is just a port of a remake of sonic, probably in C.

Oof, and even the Vampire 2 doesn't have enough grunt to run it properly. I'm normally ok with a bit of bloat in exchange for some sort of benefit / ease of development, but that's nuts. It's a modern reimplementation of the game for modern hardware - the original ran perfectly on a 68000.

This is not the port of the Megadrive version, it is the port of the 2013 version (Android / IOS)

As we know from WinUAE it takes quite a bit of CPU grunt if you want to recreate something that used dedicated hardware to get the job done even though the CPU alongside that dedicated hardware was just a meagre 7 MHz CPU...

I'm well aware of the intricacies, thanks. The point I was making is that this is a port of a game made for modern hardware, not a port of the original, and the performance requirements reflect that.

Thanks for the link! Somebody should do a real 68k version of that. With a trackloader and Protracker music on two disks

Has anyone ever just reskinned Kid Chaos? It's very much the sonic engine on the Amiga.

[Aladin]

Mr Beanbag is impressive too

I don't think it moves as much level-real estate in the same time as Sonic does when the hedgehog moves quickly. In Kid Chaos there are some quick moving scenes but those seem very restricted and empty. IMHO the Amiga would need more blitting power to do so.

the best Anti sonic for Amiga is Mr. Nutz

Maybe not too much playability wise, but technically is still awesome!!!

I never played it but the screen shots on HOL look nice. Using Sprites to display the characters status is a nice touch and must be harder to implement then a easy status bar.

The programmers obviously put a lot of love into it.

Also the youtube video of Mr Beanbag also looks very good and fast.

So pretty close to Sonic then?

Different style: Sonic 1 is more straightforward on the go to the end of the stage ASAP getting rings and stages are more linear while Mr Nutz is definitely fast plus has the fly part and the recover the escaping power bars part instead of the rings, but is definitely more on exploring and less focused on the end goal in my own opinion

I think only a small portion of luddites would not see that even Sonic 1 is leaps and bounds ahead of at least 90% of Amiga platformers technically AND playability-wise. Amazing game, Sonic 2 even better.

European computer (read: a grassroots gaming mechanics and small dev tradition with little to no playtesting) vs US/Japanese console (read: professional teams and intensive playtesting) - price of games, team sizes, publisher philosophies did affect that too

Does anyone know how if there are any decent Megadrive emulators that work well on Vampire? If so, how performant is Sonic 1 and 2 on them?

[Glen M]

I'd say Quik the Thunder Rabbit plays at about the same speed as Sonic 1. If someone could rework that game engine you'd have a decent Sonic game on AGA Amigas.

[gimbal]

At about the same speed would be... about 2/3d of the speed. Which would be comparable to Zool.
