@Truck @mmu_man @zwangseinweisung @_Adoru_ the extended joystick ports on Atari STE act a bit like GPIO ports so that's why you can make something like that. But it won't use any DMA, it's all on the CPU. Advantage: cheap, drawback: slow.
On ST it's better to use an ACSI-SD adapter like the UltraSatan. But it's a bit more expensive (~80€).
@Truck @mmu_man @zwangseinweisung @_Adoru_ Note that most of time, the fact it doesn't use DMA won't really be an issue, since there is no multitasking on TOS/GEM (every disk access is a sync call). But for this demo, well.. I used the DMA to parallelize the loading of data ;)
Actually the disk DMA is very fast and takes priority over the only other DMA access, which is the ST's blitter.
Fun fact: Bad Apple is not a Demo (:

(I assume all of y'all will be watching Outline with me this weekend? I'm sure there will be some very interesting ST things released there, I hope to see some MSX too (: And _maybe_ someone will do an Amiga thing, even though it's sort of silly to do that (: )
I have ... wanted it not to be, but... well, he DOES do development mainly in Windows (if he is still at Funcom, which I _assume_ he is.)
Personally I think that's half the reason he's the only one doing ORIC demos, but... well, that may also be partially because one of the other major people who did them passed away a number of years ago (Twilite, who gave me my ORIC.)
