I do not know structure of PB files, normally 1st half of the data is the attribute, and 2nd half is the bitmap, i can check if you send a attr PB file. But if you do not want to convert huge amount of files to PNG, then EP128emu screenshot works fine
I do not think that 4/16/256 colour attribute mode was ever used, those are totally useless, the resolution is decreased, but the number of available colours does not change, and used memory is also the same like in 2col attribute mode.

Wow, nice work!

The same space shuttle appears in the C128 VDC DEMO: https://csdb.dk/release/?id=44110
Sorry for the photo quality, picture taken from the C128's RGBI output first converted to scart: https://web.archive.org/web/20220423163100/https://sites.google.com/site/h2obsession/CBM/C128/rgbi-to-scart
...and then feed into a Medusa.

Have a question about attribute mode.

I can't fully understand sequence of storing pixel and colour bytes in PB files.
Also PaintBox has strange video modes (2col/4col/256col attributes). Are they same or have differences?

A bővített EP64-nek gyorsabb a videomemóriája, mint a nem bővítettnek?

A videómemória nem, de a többi igen
Azaz pont az a memória ahol a BASIC program fut.

Here is archive with all original files.
I change extension to .PBX (to distinguish from other image formats).
