loonies did this hours ago!!! although their implementation was in BASIC, so i guess this is a worthy release.
still, it's not full hd!!!

a bit bright on the grey side, but the soundtrack works really well with this palette

8 bytes on a non-DOS platform. respect.

Not as big a feat when you consider that the file header is left out of this number. The file is 10 bytes. And in this particular case, those extra two bytes (the load address) are essential to make the code work, as they make sure it is injected into the CHRGET routine.

Anyway, some improvements are possible:

1. Replace
Code:INC $D020

Code:LSR $D020

to make the code work even when executed multiple times. This fixes the "bug" that it currently has where pressing RETURN will change the screen color away from grey.

2. Replace
Code:LDA #0 STA $D011

Code:LSR $D011

which just as effectively clears the DEN bit, blanking the screen, to save two bytes.

3. Inject at address $84. Then the final byte, at address $89, will already have the value $D0 as needed, so it can be left out.

All in out, we can get down to 5 bytes payload, for a 7 bytes file size. :)

even more awesome. i know nothing about c64 really, so i have respect if somebody reaches sizes like me for msdos ( because nornally nobody does ^^ so I figured stuff is harder on c64)

i'm still waiting for an experienced c64 sizecoder to port “dragon fade“ (for example), because the underlying technique is platform independent, but I don't know how to port it ^^

smallest is 16 bytes so far, so 32bytes on c64 should be possible? =)

What do you mean "smallest is 16 bytes so far"? This prod is 10 bytes, and I just described how to reduce it to 7. :)

“dragon fade“ is 32 bytes, in “leaf“ (.pack) there is a 16 byte version

Dragon Fade
Leaf Pack

I'm sure it's possible in 32b on c64, i just don't know how to do it ;) Just mentioning it, since you reach about equal size regarding another problem =)

Ah, you were talking about the other intros. Got it. Hmm, I'll have to think about that one. ;)

actually, krill of plush, the speedloader overlord made all this obsolete, my pants and jaw are down: it is doable in 2+4 bytes.


i bow.
