Quote:Try to save Turrican II screenshots in Koala format with VICE. Messed-up screens without any visible graphics, nothing else.
you should report a bug then :) you have probably triggered a corner case where the conversion doesnt work right.
Quote:I also don't like three keys should be pressed simultaneusly to take game screenshots in latest VICE version 3.4. Much less used shortcuts using two.
use the nightly build - then you can use the "pause" key to save screenshots with auto-generated names |

Unfortunately koala pics only allow you to have four colours in each character sized cell, and even then one of the four has to be common across the entire screen - it's a limitation of the graphics mode.
There are other c64 video modes that have fewer restrictions, but none that allow any multicolour pixel to be freely selected from the 16 c64 colours regardless of what the other pixels are set to. |

That, and of course it gets even messier in games, when you have sprites on screen, and perhaps hires and multicolor elements.
Edit: i played around with it a bit... in Turrican its really bad :) Another problem is, when you have multicolor GFX on screen, and eg the play area is scrolled differently than some other part (score board), the whole color cell alignment is broken, and it will no more work in one koala image-
That said, i am rewriting the code in VICE to a more generic solution that will then also work with "mixed mode". Obviously still the same restrictions apply though :) |

Yes, but if it is supposed to be lossless someones up for a disappointment. ;)
@CommFor: Why does it have to be Koala format? |

Quote:I want to make BBT files out of C64 games - it's a BackBit format allowing slideshow up to 10 Koala pictures, 1 SID tune and text infos for each game (game is also included in BBT file).
I guess it is for some kind of start menu for this product https://www.backbit.io/ |
