Just an update, I am also making a TI-86 version.  The video memory == alot more speed since i dont have to fastcopy.

Ya, seriously, that's the coolest thing I've ever seen, keep up the good work!!

Not to be Anti-Emo, but the tight pants are bothering me

I would have put this in the graphics section, because it is technically graphics, but I decided not to, because it is coding, not sprites.

So here's what I need.  I need 22 different routines that will animate the tetris background. The 2 areas that need animation are the far left column, which is Plotsscreen, and each byte below it (pixel columns -7), and the other, larger column, Plotsscreen +7, and Plotsscreen +8, and the bytes below it, (pixel columns 56-71), the only requirements are that the routine be under 5000 t-states, and not use any RAM other than plotsscreen (that means no adding sprites, you have to make it mess with what's already there [look at the screenshot in the other thread]).  You should post your entries here with the code, followed by how you want your name in the credits, and a screenshot of it in action.  This is not a competition, since I don't expect I will get more than 23 entries, it is just a way for you to get easy credits .

EDIT: sorry if I kinda ruled basic programmers out on this, but it is an ASM project, I had no choice.

Here's a sample, the code that makes it spiral:

CODE

ec1 bg_0:    ld hl,plotsscreen    ld de,12    ld b,64 bg_loop_1:    rlc (hl)    add hl,de    djnz bg_loop_1    ld hl,plotsscreen+7    ld de,11    ld b,64 bg_loop_2:    rrc (hl)    inc hl    rrc (hl)    add hl,de    djnz bg_loop_2    ret c2

I am officially ignoring all bugs found for non-mirage shells.  This is a mirage game.  If it does work on another shell then that's awesome! :thumbup: but if it doesn't I will not add any extra code to make it compatible.  I've added the pause feature, and now it only scrolls on the 83+ SE, and 84+  BE/SE.  I did this because those models have the 15 mhz available, whereas the BE does not.  Sorry.  And no, that's not grayscale, but it sure as hell looks like it at 15 mhz.
Below are some screenshots:
Please note that they go faster than that, it is just calccapture slowing them down.


83+ BE (Emulated with PTI):


83+ SE (Emulated with Flash Debugger):


And to answer your question, yes, it is in 83+ ASM.

Nice idea, ty


i dunno about a wider screen, i would have to rewrite the entire game, which currently depends on a set width.  But maybe a separate version  :thumbup:



EDIT:  I have added the instant drop.  Please keep making suggestions.  The more stuff I add to this, the less bored you will be in physics

My asm way of doing it.
