Author here. Monochrome only, and it downscales. Only 1/4th of the pixels' IDCTs are computed, for "speed". It is also hardcoded for 640x480 images, again, for "speed" :-) It's based on picojpeg, heavily r

Hi, author here. It's not about business (or being bought). It's about my hobby. This is the email they sent me: --- Your BurgerDisk project is an ingenious way to modernize Apple II storage, showcasing your expertise. This is Em

When implementing my version, I have noticed that the original Shufflepuck (with no anthropomorphized opponents) also did use the EOR trick on the player's paddle. Shufflepuck Cafe, on the other hand, draws it "cleanly". I s

Yes, Princess Bejin's telekinesis sound effect is different depending on which side she'll serve, which helps a lot. This is universal as far as I know.

It's moire, an effect of the browser scaling the dithered image

Oh yes the dithering takes 10 seconds all to itself. The Quicktake 100 format is much more simple (4-bits nibbles) and it still needs 22 seconds to decode 640x480. (Decoding and dithering are done in two passes for memory reasons and space

Every entry will be used, it's to scale X/Y coordinates :) And indeed, those 0.2s are dwarfed by the rest of the algorithm (10 seconds)

To be fair, starting with the Apple IIe, the $C019 softswitch is a good, light way of syncing to VBL. Doing it with the mouse IRQ has an advantage when one requires a mouse, though: it works the same way on the whole line of Apple II compu

This is the scalable and hard way :) I had no memory pressure issue with this game so I went with preshifted shapes instead (as described in page 4 of https://mirrors.apple2.org.za/ftp.apple.asimov.net/documenta... ).

I didn't create it, it's Motter Tektura 9pt ( https://fontsgeek.com/fonts/Motter-Tektura-Normal ) and I manually fixed a few characters that looked bad at 9px. On the splash screen, it's just an image, mad

Most of us throw that in the form of an HTTPS-stripping proxy on a Pi :)

Yes, although the zeropage is quite cramped. There's only about 8 bytes free there if you don't want to overwrite anything. Accessing the zero-page only gains 1 cycle out of 4 needed to access non-zero-page memory locations, anywa

According to people at CryptoAncienne ( https://github.com/classilla/cryanc ), a 25MHz 68030 needs about 22 seconds of maths to handshake a modern TLS server. During that time, most servers close connection. So on an 1MH

Hi! Author here. That was a requirement until this week-end, but I've done some work to support II+ without 80-column cards this week-end. The menu is toggled instead of being on the left.

Hey folks! As the author of this, I'm touched by your kind words in the comments! I feel like I should quote some of you on the clients' page, because some of these comments really reflect on the reasons I wrote this.
