Shinobi Arcade Conversion

[flibble42]

I would like to clarify, when i say more than 256 colours that is over the entire game NOT per level. So cutting it down to 64/32 per level is a reasonable ask i think.

If scorpion allows it with a decent performance why not?

And then, from the reduced A1200 version, go then on a reduced again OCS/ECS version ? (if possible ?)

Yeah, for entire game i agree .

I posted the YT link to the MD version (it's an homebrew of course) and it has beetween 30->50 colors on screen at the same time, and as you can see, this is not bad at all .

Have you seen @BasementApes Rastan? I think with that sort of GFX work Shinobi could look really good in 64/32 colours.


I was watching the MD port a few years ago and it looked very promising and VERY nice.

Yes, so with ocs and its 12 bit colors, it would be a bit better than the MD one .Except if you choose the dual playfield mode, more limitating .

This is why an AGA version should be more easy and practical to do,you can preserve all colors and dualplayfield.

yes. Or a very good 50fps OCS version but with no parallax at all.

Yes of course, it would be possible to do a better job in every way, than
the atrocious official one.

In my case dual playfield is off the table, Scorpion does not currently support it, if you are coding in ASM maybe it could be an option.


In my tests i am using Scorpions sprite system to allow a wrap around background effect.

Ahh the 80s, lots of Ninjas back then

Not in the UK - no ninjas here in the 80s!

Hi, i finished some of the bonus parts, perfect and failed are done, i'll post some videos when i have tested it on the real thing .
for the moment just a few screen shots(it's close to 100% arcade):

looks good. Can you tell more about the project? is it scorpion or asm port? Are some regular levels running?

[DanyPPC]

Awesome !

Arf, i 'am a little bit confused because it's not an amiga project, but a nec supergrafx one

[jotd]

is that a 68k port with original source code, and could it be adapted to amiga? (not saying you should do it but is it possible in your opinion).

Supergraphx has a variant of the 6502 so i wonder if that can be transcoded

possible ? of course it is, the question is, what concessions are we capable to accept?
I think this game needs a dual playfield mode, so 8 colors / playfield.Can we store all Gfx,musics and sfx with 1 Mo ?
The game globaly is IMO doable in term of what the amiga can display .

The code is not difficult to do, even without the source code of the arcade .

The original arcade is 68000 so no need to transcode anything

I don't want to end up with a shitty cut-down version like the one we already have. If I had to do this I'll do it with AGA, and even with AGA it would require concessions.

Not difficult but tedious and with an average result. Then you don't have the same behaviour of the enemies, and you spend ages tuning the A.I or speeds. I'm sure that it's the reason of so many unfinished ports.
