ripping an entire level background image

ED-057 · Post by **ED-057** » Tue Feb 06, 2007 12:51 am

I want to try making a vert for the Amiga OCS using HAM for the background, and then see how many sprites I can get on the screen using copper lists and other trickery. I'm looking for a background (in any common graphic format, BMP, JPG, whatever) to start off with for the "proof of concept." I could paste together some emulator snapshots from a TurboGrafx game but I'm wondering if there is anything like this online already or if anyone can think of a better source (with more eye candy) that is still a single-layer scroll.

cave has a few maps of levels on their website. they are small, but you could enlarge them to get the idea.

Sorry for the bump, but what exactly do you mean by copper list? How exactly are you handling your sprites on the GBA?

No copper lists on the GBA

I'm talking about the Amiga. I feel that the Amiga is sorely lacking a quality vertical-scrolling shmup (probably because of the limitation of only 8 hardware sprites) so I want to make a kind of demo to see if it can be done. See, theorettically one can use the CPU/copper to reset some hardware registers during the display period and show more than just 8 sprites that way. Haven't started yet though, as I've been busy (playing Langrisser III mostly)

Oops! I immediately saw "HAM" and thought you were developing on the GBA. So copper lists is a hardware feature only? I thought it was another trick similar to linked lists.
