List of C64 Custom Graphic modes and descriptions
Hello there. I am compiling a list (with screenshots) of various c64 graphic modes to be placed in my website. At the moment I have the following.. If there are any mistakes, please let me know..
FLI
Color bank updated everyline by forcing a badline (two freely placable colors in each 4x1 attribute. third color is the same for each 4x8 block. seperate background color. $d020 can be changed every line
IFLI
Same as above but two FLI images flicked back and forth with the second frame shifted a hires pixel to the right to cause apparant higher resolution
UFLI
Underlaid x expanded sprites under AFLI once every two lines?
IUFLI
Same as above but interlaced
X-FLI
Multicolor underlaid sprites over FLI every line. less screen width. is the FLI hires or multicolor?
IXFLI
Same as above but interlaced
HOI
Sprite overlay over hires bitmap, interlaced to produce 9 possible mix colors freely placeable in the 192x200 area
MCI
Same as IFLI except multicolor mode. normally used as 4 color multicolor images flicked to create 4 color 320x200 (although there is a possibility of around 9 shades)
EXTENDED HIRES
Underlaid sprites on hires bitmap. Similar to UFLI except normal hires 1 col bitmap mode is used?? used in chorus demode (terminator pic) + higher love / grafitty
Any others?? |

In the FLI mode, i think setting $d021 every line would be more appropriate than $d020. But this only works in multicolour FLI, not hires FLI a.k.a. AFLI.
Concerning IFLI, flipping $d016 not only every frame, but also every line as well, with a pic drawn for that mode, should considerably reduce flickering. |

ooops.. dont know why i said $d020. I will also add interlace methods (eg the alternate $d016 per line) as you mentioned as well as masking methods (as used in the Black and white woman pic near the end of krestology) I assume that was just an interlaced multicolor sprite image with $3fff masking. any other examples of demos which have custom gfx modes.
I currently have took shots from
Krestology (SHF, SHIF, Masked $3fff interlace)
Digital magic (XFLI, IXFLI)
Deus Ex machina (IUFLI)
Pheonix (Batgirl pic UFLI)
Dutch breeze (FLI)
Demode / Chorus & Higher love(Extended Hires) |

you are not strict enough with the terms.
FLI:
what is a "color bank" ? What does it mean it is updated every line ? What is a badline ? What does mean that the background color is seperated ? from what ?
IFLI:
flicked? how fast?
UFLI:
what is AFLI ? not mentioned here anywher ? :)
and so on :) insiders understands right away what you want to say, but for someone who never saw a c64 this is not understandable. Depends on what is your goal with the site. |

only a brief description was placed here. obviously the finished article will be more indepth. Still not 100% sure regarding the XFLI/UFLI modes. are they Hires FLI with multicolor sprite underlay (XFLI) every line
I know UFLI is once every two lines AFLI with 1 layer of x expanded hires etc.
I dont think there are any other modes (obviously the other modes (hires sprite outline overlay on multicolor image, etc) will be added

@Oswald
AFLI = Hires-FLI (don't know, why ppl came up with this...)
@algorithm:
IUFLI is called UIFLI! (Underlay interflaced flexible line interpretation if I'm right...)
Your EXTENDED HIRES is often reffered as SuperHires (SH) or SuperHiresInterlace (SHI) [for examples look here: Super-Hires Collection or here: http://noname.c64.org/csdb/release/?id=4753]
Crest/Xbow then came up with putting FLI into it so (SHF and SHIF [F.e.: http://noname.c64.org/csdb/release/?id=7176] according to Deekay... ;)
About XFLI you should take a look at the editor, I think it should be on one of this disks: Digital Magic or ask Dane about it. [Edit: Tested the editor and it seems that there are 8 MC sprites under a Hires-FLI pic resulting in a 192x167 [mhmm, why not 168? Stragnge...] picture and the FLI [obviously] every second line, but better ask Dane, I'm too stoopid for this...]
Oh, another idea: Would you please be so kind and link the editor for each graphic-mode (would be even nicer to have ALL the editors for that mode... Okay, would be a little bit hard for FLI but for the others it would be quite nice!)

XFLI is AFLI every line with multicolour sprite underlay + the option to change a spritecolour every second line.
Another version is XLFLI, which is AFLI every second line with 8 multicolour underlay sprites. For examples, see Phases and Cycle. |

@Dane: How much sprites are used in XFLI then? I always thought that more than 6 Sprites on FLI without tricks are impossible? |

You can have 8 sprites on top or under FLI with no problems. however it would not be 'full screen' The record at the moment - which may not be beaten is six sprites over FLI full screen (with the obvious 3 chars gap at the beginning). But seems to be less control over the sprites in comparison with (for example) Demus Interruptus by Crossbow which has 5 sprites over full FLI |

8 of course. But only the 25 charcolumns to the right on the screen are usable. |
