As a fan, Shinobi was the shits for Amiga standards, a bad day at the Sales Curve office ------->

There is some parallax but I would imagine the most difficult part would be the bonus shuriken stages and keeping the framerate. Have to say those bonus stages back in the day looked absolutely stunning when all I had was my lowly Amstrad CPC lol. |

- they retained parallax scrolling, even if the scrolling is anything but smooth - the behaviour and enemy placement and all looks very similar to the arcade. - the enemy & main character moves are there. It's just choopy & washed down. Looks to me like a failed attempt to reproduce the arcade faithfully, because OCS just cannot cope with the original hardware. We'll wait for any OCS versions or mockups, even using Scorpion, let's see it any are better? Personally I'd like to get my hands on the sprites, with proper indexing vs original code, as MAME doesn't allow to display or rip them for this particular game. |

Isn't the Scorpion Engine perfectly suited for this kind of game ?

The goal is to be close as possible and using the hardware at it's max . Quote:

Well I've tinkered with the idea of this in Scorpion, on and off for ages. A prototype would be easy enough, have the maps and main char sprites all ripped for a start. The polish and finishing is another thing.
Ultimately, it would not be an easy ask in Scorp. Fantastic as it is, there are some stumbling blocks that require clever tricks, the super power ninja screen fx for one! Unless major compromises are made it would also have to be AGA, though annoyingly much could be done in 32 colour am sure, maybe even 16 with some real clever palette changes. To do this justice would really need asm and you can count on one hand the amount of people willing and/or capable to tear down and rebuild an amiga version in asm from scratch. |

I AM interested. I think I can rip the 68000 program myself from MAME but send all you have if it's not too much hassle. Quote:

Awesome if you can modify the arcade engine 68000 ASM code for the amiga I'll join also the decrypted version of the shinobi arcade code |

Jotd - If you think you might benefit from any of the Sega sprite/tiles stuff I've been working on, give me a shout. It's quite c2p bound though.

The usefull thing would be to have sprites and backgrounds in their bitmap mode, and not in tile mode .

tile mode is the best to be able to reuse the original code.

I wasn't aware the Shinobi source code was available, or do you simply not need it here? That said, regardless, if you convert this that will be a massive achievement and a nice step up from those already impressive 8 bit ports.

I said "original arcade code" not "original arcade source code". It's 68000 so there is less need for reverse-engineering as no transcode should be needed. A bit like patching a game with whdload, except that instead of patching protection & disk loading, you'd have to fix all graphics & controls & sounds.
If we consider Rolling thunder, source is not available either, but it's using dual M6809. The sprites & tiles are easier to rip (from MAME) and graphics are simpler but the dual M6809 without source part is a challenge for me ATM. |

I mean tile mode just a vram/rom capture .
You have to reassemble those tiles, by hand to rebuild your backgrounds/sprites . Do you think that this kind of data, is really exploitable ? Without the tilemap, those tiles are useless . Quote:
