he mentioned the term "branch and link", this seems to be -- something

to make a jump instead of subroutine call and then return of it, takes much less cycles.. only if it "returns" to the same prog counter most of time
mirrorbird(23:42:16)
but i think he's actually self-modifying jump-addresses, to avoid doing RET (to save a pop??). that sounds insane. but that's how i read it

Galaxian dude has 'blogged' at me a bit about his z80 micro-optimisation, which of course i barely understand bc i have written very little asm in my life

if i don't do the recordings in a well planned sequence and the little post processing, it could mean 30min..1hour per (3 min) tune

mir i got some c64's too, to pick the best sounding chip included.. but yeah, lotsa work

btw a guy sent me his unfinished Galaxians arcade conversion to the speccy, very SMOOTH, i think he's going for 50fps. but you can't shoot aliens yet, bullets pass through. i'm like: oh no the aliens have invented a PHANTOM DRIVE, it's over for Earthcels.

but the number of people around here who know how to do a good recording (cough, studio nerds) and probably have the hardware -- is quite high
