Rotations tiles code - ASM?
Код вращения спрайтов/фонов на АСМе?

Vertical column scrolling + horizontal line scrolling

Спрайты не вращаются. Да и на сеге они никогда не вращались. Боссы той же Contra hard corps, Gunstar Heroes, Exo-Squad, Red-Zone и т.д. - с пре-рендеренными поворотами сегментов.
А фоны, как уже было сказано выше:

Полный оборот таким алгоритмом не сделаешь, так как картинка сильно исказится (из-за ограничения вертикального скролла). Для полного оборота на 360 градусов нужны своего рода mip-maps для определённого угла вращения ( ну, это моё мнение).

That indeed limit the rotation to somehow -15°/+15°, above this range the deformation become too important, but i guess that is the effect you used here ?

a unique case with complete rotate 360'

there can be seen the prerender on certain areas.

Overdrive is using DMA to get 4px columns, though (the prerotated steps are 22.5º, to give an idea).

That was what i meant by vertical column scrolling and horizontal line scrolling
Just using the full MD scrolling capabilities allow you to get that effect

the game is not finished.
For switching levels necessary recompile source-code.
Also, I'm going to write the music - black-metal cover's (for now there is only one track).

Reminds me graphics from Shadow Of The Beast trilogy (Psygnosis) or Giger... I like that type of art.
