What is the definition of PETSCII?
As we were reviewing past entries for Transmission64 3rd Edition (2022) and our rules (and other party's rules) in general, there were some questions that came up with regards to the the definition of PETSCII graphics.
For example, do you think that it's okay to turn multicolour mode on (but not bitmap mode)? Is it okay to use a custom font? What about ECM mode?
I'm curious to hear what others think... (famous last words on CSDb forums). |

This is a feature of CCGMS. |

HU??? Again: how?
The only CCGMS thing i remember is that it flashes the screen on BEL (chr$(8) iirc) |

So how do you change the background/border color then? First time i hear about it - and i have never seen it on any BBS back then. |

While his claim that PETSCII's birthplace is the BBS is obvious nonsense (Frog anyone?), I still agree with Holy Moses' summary of what should and shouldn't be allowed in a PETSCII competition.
And of course Groepaz is right... as soon as you allow a custom charset, it turns into a charset graphics (i.e. logo) competition. While it wouldn't be bad to have one, it should be separate from a PETSCII competition.
Likewise, ECM is a whole different ballgame. I don't think it would be fair to throw any of those categories into the same competition.
If anything, you could consider allowing PETSCII pieces taller than 25 lines, but then you might want to set strict rules for scroll speed or even have your own viewer with which to show the pieces.
It always struck me as a little weird that PETSCII competitions are limited to one screen, when - often even in the same competition - ANSI and ASCII pieces are allowed to have 1000 or more lines. |

Quoting Groepaz

I'm with this opinion. A "properly native" PETSCII should come as SEQ file and can be viewed with about any SEQ viewer and JiffyDOS or alike extensions. Black border and background to get "the right" effect at max :)
More is a demo! |

You can drink all my Holger at X =)
So i made a file for testing that contains $02 $01 $02 $02 $02 $03 $02 $04 etc, but all it does is flash the screen in white, no other colors *shrug* Do they have to be in some specific format? |

This is good discussion and I hope it will some day lead to a common understanding of what tricks are accepted in a PETSCII compo when the rules don't explain everything in detail. I wouldn't accept ECM, and not sure about MC and border raster trickery either. In a compo context, to me the word PETSCII means "the art form" instead of "the encoding standard". I second TerrorZ' vague definition of "what can be done in BASIC screen with only knowledge of border and bg color POKEs" instead of BBS limitations.
Of course each compo can set their own rules and also accept entries that wouldn't even qualify in CSDb as a "C64 graphics (PETSCII)" release. In mixed platform compos that put single-screen PETSCII pics alongside 1000 line high ANSI and ASCII, it would be only fair to accept multiscreen PETSCII pics. Btw: Syntax allows them, as tested with Kamaji's Boiler Room. |

So SEQ files can be bigger than one screen, right. That means we'd need to allow scrolling? |
