Thums up for platform. I once coded a chip8 emulator because everyone did, but never released it. (I know this one is chip16 though)
I see now framebuffer on this one. So,. the little dots are all sprites, is it why it's so slow?
The twister also sprites with height 1 I guess. Also slow.
So, in this platform, the sprite size is fixed or you can set it up? Is the mandelbrot one big sprite or just a grid of smaller sprites? So, maybe this way a sort of pixel buffer is doable.

Thanks. Sprite size is not fixed, it may be set from 2x1 px (becouse 1 byte contain 2 colors with 4 bit) to 320x200 (becouse registers can't operate with walues > 65536).

Dots, sineflag and twister built on the general principle: i am used 32Kb sprite (320x200) for framebuffer and every time i render all image to this sprite realtime, then just show this big 320x200 sprite on the screen.

Mandelbrot alghorithm have two cyclys X and Y, and just draw small 2x2 sprite every time.

No thumb for that infestation of hell known as ngemu.com.

Such a pity that Tronix now sided with such fucking sellouts. The code looked nice indeed, could be used in a small emulator for a 64kb Windows intro.

no, why the fuck not, proof of concepts rool. If I didnt vote this up, I would be a fucking hypocrite, now would I?

Platform thumb.

Optimus: Like everybody else, I wrote two Chip8 emulators, in JS. Was a nice a way to learn a bit how emulators work.
