I take this thread was splitted from the Rygar thread. You guys remember all this discussion begun with Codetapper asking what cuts would you make to port Rygar to a Classic vanilla Amiga ?
I really don't see the point in having a perfect port of the game but needing lots of cpu+ram to make it work... I could just play it on emulator at this point. IMO the real interesting challenge is to discuss how to make it work on 68k ECS chipset 1mb or 020 AGA chipset 2mb. What we had back at the time. How would you make it work? That's how Sandruzzo's Rygar was born. You surely can't have a pixel perfect port, but I am pretty sure we could have a much better Ghouls 'n' Ghosts than what we had. The Master System version for example... it takes some liberties with the game, but even if we ignore that, the base here is pretty good, the game was a lot fun to play... and I doubt the Amiga would have any trouble doing something like this, and probably without all the slowdowns: [ Show youtube player ] This game is incredibly playable, really fun to play, looks pretty good for a 8 bits console.... if this was the Amiga version of the game I would've played it a lot more than the oficial Amiga version we had. |

The CPS game are 2 highs above what you can find on the Amiga 500.
It has a 1mb program, 256kb of samples, and 4-7mb of graphics. Even in 16 colors, that's bigger than anything you can find on an amiga 500. i would love to see a good port of SF2 on A1200 for instance, made with Anima's method. |

A wise choice would be to use an Amiga with something higher than a 68000. |

I don't think we can do worse than Amiga version. I belive that we can do a lot better!

I just say that you will not gain any speed by adding fast ram if you use 4 bitplains...

I will say the usual proverb : "who can do more can do less !". The Amiga perfectly deals with 32 colors in 5BPL, you then use the fast ram to get the max speed out of the CPU. and that's it. |

Why don't do it on A500 with 512 fast ram?

Ok.
This is not clear to me: if you use 16 colors on Amiga 500 then 68000 does not slow down (have maximal access to cheap ram) so fast ram will NOT speed anything? |

As long as the copper/blitter are idle, there is no real difference in speed for the 68000 between chipram and fastram. However, if you have an a500 with true fastram (meaning not one of those trapdoor expansions, they are 'slowram') then and only then, the CPU can still execute at full speed while the blitter/copper are active. As long as code is in fastmemory. Any Amiga with a 68020+ is always faster when using fastram. |

I would redesign the game, make smaller play area (256x192 or so) and redraw smaller sprites (32x32 instead of 48x48), and make it sort of multiload-stop action to load new stuff eg in the middle of level 1. You can't just run like that a CPS1 game on an Amiga 500 or 1200, it's too much. Look at requirements on STE, 32 Mhz and 14 mb for 16 colors.

just look at Cho Ren Sha for Falcon: [ Show youtube player ] it become: [ Show youtube player ] anyway, this is more in line what we can expect from 8MHz Atari STe: [ Show youtube player ] and please check other Anima youtube videos btw arcade Ghouls 'n' Ghosts use 12MHz 68000...

Powder engine had a trick for displaying a bunch of stuff in 16 colors and 25 fps (have feeling could be pushed to 50 but not sure) using flags that enable/disable the blitting of certain bitmaps/palettes so to have subpalettes of 2/4/8 colors and was working in a 500 1.2 with extra 512k fast; since the source is not completely license clear for public display, if someone want to give it a look to see if any of those tricks are usable can PM me.
