I FINALLY had a bit of time to sit down and fiddle with this for a bit. It is super fun. I am basically thinking of making little abstract animation to make glitchy transitions between litewall / glitchnes. or to make borders to overlay on scrollnes.

Thanks huge amounts nick!

but there are different mappers that would allow for more frames, yeah.

Is it possible to use more than ten .nam "frames"?

yeah, you're only limited by the mapper you use, i think. with a basic nrom mapper, you get either 16k or 32k to work with and each nametable is 960 bytes.

Im already pretty comfortable with YYCHR and Shirus nes tool thing and you dont need to convert the frames. Also if you do something with an animated gif I assume you will get little imperfections and distortions if the gif isnt PERFECT nes graphic spec. Animations with logones should be really crisp.

Mosre optjons are always good!

well, since you want to animate, why not use NESflix?

i'm sure it could have been done better but hey, it works.

with logones, pressing select stops the screen from scrolling, if it is. it still does that but now, if you HOLD SELECT and then TAP START, the screens will start animating. it goes through each screen and then starts back over at the beginning. to turn the animation off, hold select and tap start again. pretty easy.

scroll down through the code until you see "NMI:". a few lines down from that you should see a little note i made that says "change this number to change the speed of the animation". the number right now is "#$20". that's hexadecimal so change that to whatever number you want between 00 and FF to change the speed at which it animates. smaller numbers are faster. change it to #$01 for hyperspeed.

just copy this quote into a text file and save it in the logones folder as logones.asm, replacing the one that's already there.

I just had a bit of a brainwave which might be useful for logones users. 2 questions

Basically logones is a set of ten "screens" is this extendable or is it a hard limit? could logones use 20 or 30 or 40 screens if I created extra .nam files?

Second, at the moment A and B cycle through the screens. Is there a little code modification to make logones automatically cycle through the screens, either as a loop or ping pong?

Reason for asking is this would effectively make logones into a simple NES animation tool. You could make one .nam. load it into, YYCHR or whatever, alter it slightly, save the new one, load it, alter it etc, to create "frames" of animation rather than static screens.
