@Luca:
I can't fill in all the details, but i'm gonna try:
As far as i know the linetunnel is charset-mode only.
Wobbler and Easter-Egg operate on a zoom4-mode. Its basically the same screenmode as in the 2nd part of Haziasan: Its zoom4 in character-mode with a special charset to form a 160x100 monochrome-screen. You set 8 pixels (a 4x2 rectangle) with a single STA. Haziasan used the color-attributes (40x50) to colorize the pixels itself, Wobbler and Easter-Egg use the color-attributes to form a backdrop-picture. Mind the rather big textures!
The psychedelic bars have a similar display-code as 1k-Plasma or my Plasma from 8SOB. Its FF06 to prevent/skip badlines and FF1A/1B/1F to pick a row from the texture plus FF15/16 to add colors. It uses a different texture though and adds that rollo-text. Brainwash used a similar technique but with a rather unstable timing and no color-changes.
The Arte/Sanity-Lookalike pokes FF06 to prevent badlines aswell and does FF12/1A/1B/1F to pick rows from multiple texture-bitmaps. Additionally it does FF07 for the bends and FF15/FF16 for the colors.
The Voxel-Landscape is Zoom4 too. Its got quite a huge height-map i think.
