Sonic the Hedgehog for C64/128 + REU
We're proud to announce Sonic the Hedgehog for Commodore 64/128 + REU (PAL and NTSC).
This is the first game that has exclusively been designed for the REU, to make a fast and smooth full-screen scrolling version of Sonic with little compromises.
This game is a direct port of the SEGA Master System 8-Bit version of Sonic the Hedgehog, with about 64 KB of code hand-translated from the Z80 to the 6502 architecture.
The game will be released as a free download in the coming weeks (exact release date to be announced).
It requires a C64 or C128 (in C64 mode), a compatible REU of at least 256 KB, a compatible drive (.d64 and .d81 images will be provided) and any joystick or gamepad (no extra buttons required). On NTSC, a C128 or other CPU accelerator is highly recommended.
In the mean time, here's a trailer and some screenshots:

Looks really cool. Probably a lot of gems could be ported by utilizing a little extra power of memory & DMA. |

Judging only from the teaser video, this seems another quantum leap of C64 Gaming made possible by Mr.SID \o/
definetely gonna make some ppl use their REU - no matter if real or unreal hardware or emulated |

I guess it stands to reason that the REU is needed because of the huge amount of background map data that has to be pushed around when Sonic starts flying. Would a cart version be possible too? |

I guess not but wanted to confirm.

I had wondered who was behind the pixels?
Today i read, Oliver Lindau (Veto) is behind the pixels.
A good choice, as some artists would have opted to overload the screen with crosshatch patterns, which look great from a distance, usually work less well for games, other than in small doses. |

What bugs me a bit at the moment is the music ... I'm not saying it's bad (far from it, considering that you have 3 voices to play with) but it's more to do with the tempo speed. I don't really remember the 8-bit Sega Master system version that well other than one of my cousins had one ... but did it really play at that tempo on PAL systems? Besides, "NTSC speed" seems more popular with fans of the game franchise (8-bit and 16-bit versions)... all the youtube videos / memes and so on.
Other than that ... what a fantastic looking conversion! I never thought this would be possible! Nice one, Mr.Sid. :) |

I have to agree with Conrad.
It plays faster on Genesis/Mega Drive. I haven't seen SMS version though.
@Veto is it you who made the gfx? |

Yes, I did most of the graphics here. It is a mix of stuff I pixelled on my own as level bg/animations, intro and interlude scr (edit: still close to the original by Ayano Koshiro). Sprites turned out as kind-of a coop with MrSid. The ending was done by MrSid. |

This is a wonderful project and I can't wait to get to play the game!
Speed depends on PAL/NTSC also on the Mega Drive/Genesis. I like the music on NTSC more. Comparison: https://youtu.be/DW-XsGN8oKc |

I would have thought that the original game speed should be that of NTSC - given that the original game was developed by the Japanese, and they use NTSC like the USA.
Best way to determine the correct speed would be the Game Gear version or even the mobile app version - as they are video system and region neutral. To me, those versions sound NTSC speed. |

Correct. Europeans are used to this 20% slower speed game and music. NTSC land (60 hz land) are used to a faster version - which is the speed it was develped for. In modern rereleases of the game SEGA fixed the speed in the PAL version, in many cases - for example for the Dreamcast if I recall correctly.
Said that, Europeans will probably feel completely at home with the current speed.
Awesome job, guys! |

The speed of the music in this video works well.
https://youtu.be/SQPvA0OvR24
It appears the music speeds up from time to time.
Watching the video in the link provided, i never knew the Master System was quite that good.
Having never played a Sonic game, it will be good to give the C64 version a proper play through. |

It was clearly composed at NTSC tempo and just because they did a bad job porting the music in the 80s doesn't mean you couldn't do a better job today. I fully respect that there may be technical limitations preventing it, but if the songs have tempo settings that can be adjusted to compensate for the slower playback frequency that'd be a great option to add. |

@Alta I see. During the video, the opening level, something causes the music to either change slightly or speed up slightly. On picking up the boots, the music speeds up dramatically. |

@MagerValp Correct. European/UK in most cases tended to get a slowed down, squashed screen take on the US/Japanese release.
Sonic looks round on NTSC. Sonic looks slightly squashed on the PAL version. That is why i picked up a Japanese Sega Saturn (with stepdown converter) to experience full screen, full speed games. |

So, an update with selectable music speed is already on the wishlist :) |

So there's some video updates on Lemon.
Release date is 19th December.
Also running it on NTSC apparently gets the accurate music rendition.

SEGA typically doesn't send its lawyers after non-commercial fan games. There's a whole festival of fan-made Sonic games (see https://www.youtube.com/watch?v=PRY8JLlE3VA) so I trust that they're smart enough to see that this is a labor of love and a homage, and not someone trying to make a quick buck. |

Yeah, SEGA is going a different way than Nintendo, which does unofficial conversions such as "Super Mario Bros." get banned immediately. At least as long as no money is made with it. Although there would be some people who would pay for a boxed and cartridge version. :-)

You just forget that you're playing Sonic on a C64. That's how good it is.
I just wonder how this achievement is ever going to be topped. There's plenty of other popular videogames that could have a C64 port (or improved on from the official versions).
I keep thinking a Zelda or a Pokemon port should be do-able at least... and the shadow of Doom looms large (might be possible to translate the SNES version, as it doesn't use the PC doom engine, and run it on the SuperCPU. The SNES source was released last year: https://github.com/RandalLinden/DOOM-FX) |

Yes, but that straight port of Doom was too slow to be playable - unlike Wolf 3D.

In the twitch stream I heard the game "Truxton" thrown around.
An actually competent vertical scrolling SHMUP on the C64 would be nice - although "Slap Flight" and "Terra Cresta" were pretty decent.
Personally I'd like to see "Twin Cobra" or "Raiden" with 2 player simultaneous - or a remake of "1942" done properly. Those are my favourites. |

Yeah, Dune 1 could be doable, if you wear out a few fullscreen graphicians... :) The game has tons of screens, and flying sequences, etc. Not exactly trivial, and you'll need a large cartridge. |

I dont think dune 1 is very doable, remember all those globe-map views. The map is essentially on a 3d sphere. Also the orni flying scenes would suffer horribly. Then the characters layered on top of backgrounds wouldnt work well in 160x200 and with the multicolor bitmap coloring limits. |

the issue is the bitmap mode. The drawing commands don't handle the 64 very well. However the VDCM mode which is 160x100 16 colours works fine, so all one would have to do is port the quill engine and done. You also have 128K for the larger adventures. |

As for the topic, i'd like to read something more about the technicalities.
Like, how much data is DMA'd on average, per video frame, min/max, to/from, in border or everywhere, etc. :) |

Amazing port! Wondering if more games would be made for REU back in '80/90s would contribute to its popularity. Was the REU price the barrier? |

Quoting DiggerWas the REU price the barrier? Absolutely. RAM came at a premium back then.
A quick websearch brought this up:
"In my March 1987 issue of COMPUTE's Gazette, I found an ad for the 1750 in the back of the magazine. It cost $169, which is the equivalent of $375 in 2019 US dollars. For half a meg. As a comparison, that same vendor sold an entire C128 machine in 1987 for $239." |
