If I remember well Tony told us, that even OCS can address 1mb. |

My honest opinion is... do a game in 16 colours, using some nice sprite tricks for the parallax.. and find a good artist that can work in 16 colours (there are quite a few around).. and produce something original, even if inspired by a classic coin-op
Target OCS.. 512k chip + 512k any other ram... and you will be on to a winner. |

AFAIK only the ECS Agnus models can address 1 MB chip mem, so 8372A and above; the original Fat Agnus (8370 and 8371) in the early A500 and A2000 cannot do that IMHO. Some confusion might stem from the fact that there where later A500 (and A2000) with ECS Agnus and 512k chip + 512k slow via expansion, where the chipset could use the whole 1 MB as chip, but the slow mem part at a different address range than the cpu (and as always, there was some demo relying on that behavior, by Lazy Bones IIRC).

And how many games required ECS back in the day??
basically, you target OCS/ECS or AGA would be stupid to only target ECS... and I am sure many (most) would agree |

The A500 is a bit confusing in that several revision of it existed and some of those revisions had the ECS Agnus in it. Mine was one of those, after cutting a trace of the board I got 1MB chip instead of 512+512K.
Perhaps you had something similar? |

*AFAIK there are some Rev. 6A with OCS Agnus; Commodore, in being Commodore, probably just put the leftovers of the OCS Fat Agnus on the board when they still had some in stock. |

On the subject of memory usage... if you keep the tiles in fast ram and not use the blitter for them then the game will fit for ocs amigas.
I have just had this brain wave sitting on the shitter. |

Surely you only need to store the tiles / sprites that are used on each level... load them from disk between levels

Basically a 16 color version with multiple copperised colors could come pretty close to the 32 color version, in some cases even surpassing it. F.e. many parts of the background can be remade to be exact copies of the arcade with 3-4 copperised colors. The downside is dma usage, big copperlists and a dedicated experienced artist (with loads of free time) to convert the assets. Quote:
