Played a little with debug tricks on the other game...identified that isn't actually Sonic Dragon but Super Taiwanese Baseball League ![[Linked Image from mamedev.emulab.it]](http://mamedev.emulab.it/kale/fast/files/0128_757331201.png) ![[Linked Image from mamedev.emulab.it]](http://mamedev.emulab.it/kale/fast/files/0130_907220098.png) Sprites are missing/wrong because it uploads a G. Clinton-esque scatter-gather DMA list at e90030, weird because it does: ff637c src f00010 dst 2f size b900 paramf00010 is the video DMA, and here's the title screen list: ![[Linked Image from mamedev.emulab.it]](http://mamedev.emulab.it/kale/fast/files/scatter_gather_list.png) I've told you it was funky, no?

Is it that DMA is wrong, or could the game be re-basing the sprite data area, as I described in my post from a few days ago?

As you can see from the title screen (and the garbage that it puts shortly after it), data is missing, so it's a weird way of doing scatter-gather

Wow, I didn't expect to suddenly see A'can emulation getting anywhere so soon. I wonder where these ROM dumps are coming from, maybe all games will be dumped soon? Save the extra rare Rebel Star. Doubt we'll be seeing that one anytime soon.
