Well... you could do some of that with just a floppy and an A1200 with WB3.0.
You are a bit constrained for memory to display animations, but stills of sprites and still art, that's doable. If you can save or convert the stills to IFF format on the PC side, Multiview on Workbench could display them.
As for screens, if you are based in Europe, something with a scart connector should do just fine. Mr steady there does very very good Amiga-scart cables. You could call him the gold plated standard on scart.
Genuine retro CRT monitors cost a bomb. They're only going to get rarer.
You DO have phono out in color on an A1200 if you are based outside Europe. still a fair amount of old CRT TVs (video monitors) and early LCDs can connect there, but you get a fuzzier picture.
I would strongly recommend you fit a hard drive to the A1200 and upgrade it to 3.1 to make the project easier. Then you could more easily use graphic formats other than IFF (PCX or BMP or JPEG). Or run Art Department Professional to convert them, choosing a set pallette of 256 colors.
Or run an Amiga emulator to get the graphics tweaked, and just use the A1200 to display and check them on real hardware. Once you get the adaptor working, you could save your Kick 3.0 ROM with a tool from Aminet to run the emulator with.
The sad part of the A1200 is the Gayle issue. Because you can't get the PCMCIA working properly without a fix from aminet (CCReset) which you can't transfer to the Amiga without having a working compact flash solution.
I was under the impression that I could use the pcmcia card as a sort of hard drive/storage space?
It's a drive, but it can't boot without Workbench having the driver in devs... which if only stored on the compact flash card, can't be read.
You can't boot a system from a compact flash card plugged into the PCMCIA socket on an Amiga for this reason. Chicken and egg situation.
But it's a lot easier transferring files than unplugging a card plugged into the guts of the Amiga (the hard drive connector). That might be your only way to get CCReset and the PCMCIA working.
Unimpressed? Me too. :lol
