There were 2 versions of the arcade. One had the giant punch buttons, while the other hand regular buttons much like SF2.

Looking good already. I watched a video of the Atari ST version and it also had parallax scrolling which the Amiga missed out on.
Did you find it easy to rip the Arcade data for your project? |

LOL, just looked it up.
True, also the game looks like it is running double frame rate compared to the Amiga version. Almost playable. |

So I decided to take acidbottles advice and try not to hold back on the port then cut back and optimise when finished.
Here is a preview of the japan stage with ryu and retsu. Everything is sharing a 16 colour palette I swear cutting down the stage colours will drive me to madness. Big thanks to Mike from bitbeamcannon for the great colour palette and help with the character edits. |

Are you not using 32 colours for speed reasons? |

It can but performance is not that good especially for arcades with scrolling - someone with more technical background can probably teach you some tricks

Maybe more subdued backgrounds, like this, just with more color on the characters.

Ah another thread about Street Fighter and the Amiga. And this time SF 1. Great
@msmalik681 Yes the Amiga OCS can display 32 colors and even 64 (half bright) and HAM (4096). If we remain on the "game" subject, the most used mode are 16 colors (Turrican 2, BC Kid..), 32 colors (Alien Breed, Superfrog...) and the dual playfield mode i.e. 2*8 colors (Chuck Rock, Shadow of the Beast...) Some game use other mode like the 64 colors mode (Pinball Dreams) but it is rare. The main problem for A500 and the SF kind of game is the chip memory : 512kb. There are a lot of threads about that... One good solution to manage that, and to get 50fps is to used the dual playfield mode. It means that the back has 8 colors and the front (so the two characters) only 7. Possible actually. The best proof of that is Shadow fighters : https://hol.abime.net/1888 (the chars are in 25 fps I think). I did a demo one or two years ago about that using the characters from Street fighter 2 : https://www.pouet.net/prod.php?which=88383 (youtube link in the page). I think a good SF1 port is possible on the 500. Perhaps one thing you didn't know well is the fact that with the magical great chip called Copper, you can change the color palette multiple time in a screen, so in fact the back can display many colors (the best example is of course: https://hol.abime.net/1891) I don't know if you can do that with the scorpion engine. I will do perhaps a try this evening (with the Amos language) Good luck with your port on Scorpion |

Simple SF1 POC in dual Playfield
So here is a simple implem of rendering based on dual playfield.
You can see a quick video here (A500 vanilla) : [ Show youtube player ] Here is the adf, so you can test all that in a real Amiga : simple move with the joystick left or right sf1.zip About this demo : The back is in 8 colors + some copper enhancements. With the help of a graphist we could get something better... The two chars are in 7 colors. I downgrade all the chars frames and it works pretty well. For this little demo, only the "walk" frames are used. Here is the background without the copper magic : All together : By the way, I used this fabulous tool to set the rasters : https://gradient-blaster.grahambates.com/ So I am curious what it can give with Scorpion.

That is a really well done job! Now if we add a 64x16 cloud sprite in three colors we can sorta simulate parallax in the back (and if copperlist changes colors of the sprites might look even better)
