An in-depth write-up about how I made Shufflepuck Cafe run at 60 fps on an 1MHz computer - including two-player network games.

@nprofile…valu yes, because it's supposed to work... I use it all the time, via cc65 runtime, in and out of PREFIX.

@nprofile…valu yeah, that should work the same relative or absolute or floppy or HD...

I managed to get a "for parts" #Quicktake 150 for 15 euros, it only needed 15 minutes of work to "fix it" (the Trash button was stuck down). Here's its first picture!

This new release of #Mastodon for #AppleII mostly brings you the ability to view pictures and send pictures in DHGR - Double High Graphics Resolution! 560x192 in monochrome, or 140x192 in 16 colors.
You can find it via https://www.colino.net/wordpress/en/mastodon-for-apple-ii/
Attached are two examples, courtesy of @nprofile…y5lt and @nprofile…r6sq

Not yet a release, but I think it's functional enough for a beta of Ammonoid, a file manager in the style of MC for the Apple II. It aims to be simple, and implements VSDrive so disks images presented over serial (David Schmidt's ADTPro, Bobbi Manner's ProDOS-Utils or my own surl-server) are accessible. I'd like to hear your thoughts!

Numéro 3 a grandi, je vends son vélo 20" (à Toulouse). C'est un très bon vélo en bon état mécanique, mais son état esthétique reflète qu'il a déjà été utilisé par deux enfants.
L'annonce est sur https://www.leboncoin.fr/ad/velos/3016792907
La fiche technique sur https://www.culturevelo.com/shop/frog-bikes-frog-55-165341
Le prix de 200€ annoncé sur leboncoin est automatiquement ramené à 150€ pour les gen·te·s cools d'ici avec le code MASTODON 🙂

@nprofile…kgua Sorry it's possibly the worst way to report a bug :)
Firefox 139.0.1 on Ubuntu 24.04.
If I use a wrong password, mastodon.social tells me so. If I use the correct one, I get this error page, and have to open a fresh private browser to land back to the unlogged public homepage.
Trying to login using Mastodon for Apple II works correctly, which is very weird as it uses screenscraping on https://mastodon.social/oauth/authorize

My adventures in 6502-land: I discovered that drawing lines is a pain in the ass. The reference algorithm is Bresenham's (https://en.wikipedia.org/wiki/Bresenham%27s_line_algorithm), which is really smart and good, but requires to check which point is at the right/the top of the other one to know where to start from, then which kind of slope the line has (to know whether to iterate on X or Y), and even if it involves no division, it involves a lot of additions/substractions/absolutes and branches.
Another, albeit much slower, possibility is to find the middle point (which just requires two additions and two right shifts, no 16-bit arithmetic involved), plot it, then recurse on both sides.

@nprofile…de2h please note that BASIC.SYSTEM (the "shell") handles backspace since ProDOS 2.4.3, which is out since December 2023 ! (And yes this is a huge improvement)

Next project? I'm still at the "I'll never manage it" phase.

I have removed #MastodonForApple2's image loading progress bar, because I don't need it anymore at that speed! Actual 4kB/s at 1MHz 🙂
