Is it possible to split the display in several text/pseudobitmap/bitmap
modes (say SCREEN 4 and SCREEN 5) without losing sync?
Sure. The game "Psycho World" split the screen between scr5 and
scr7 in the intro, and between scr5 and scr4 in the game. "Space Manbow"
has three
The first line interrupt needs to be at a line before line 192 and it
should set the LN bit (screen height = 212 lines). The second line
interrupt should be at a line beyond line 212 and clear the LN bit
(screen height = 192 lines).
Shouldn't the second line interrupt be between 192 and
Hi,
The overscan trick was, I think, first discovered by NOP and used in
"Unknown Reality" at the title screen. Achieving the vertical overscan
on the V9938/V9958 is actually quite simple. You only need two line
interrupts (using r#19) and flip the LN bit (r#9 b7). The LN bit selects

Hi,
Following the recent thread about the PSG, I found these interesting
emails in my mailbox from one year ago about playing 4 bit PCM samples
via the PSG. It might be educating and interesting to reread it.

Hi,
But, unfortunately, I guess I'm doomed now...
Well, you could also change your set up of your ISRs (Interrupt
Service Routine) with your line interrupts (r#19). First of all, disable
the V_BLANK interrupt, so you are left with only the line interrupts
from r#19. Secondly, make s#2
Hi,
However, one problemo...
When I set the adjust while a VDP-command is executing, there appear some
'noise'-pixels on the screen. I can avoid that to happen by exact timing of
my COPY's (execute them right after the V_BLANK-interrupt), but I would like

Then, you have the data on the perfect way to copy it directly to

How to do that in BASIC?

as far as I can see, Maarten is right. P is the intermediate result, while X
goes from X to X^2 to X^4 to X^8 as the bits of N (powers of 2) are
inspected it's a standard algorithm.
I think you misunderstood me. Maarten wrote the routine as followed:

Does anyone know how I can read the font in a graphical screen, like
screen 5?
I guess it's not in the VRAM like in screen 0 (base(2)). Maybe I can get
it
from the ROM somewhere? If so, where?
