Replay de ma présentation à l’A2FF sur comment jouer de la chiptune avec une Mockingboard sur Apple II

How to play chiptune on Apple II, original English version here:

New experimental build of AppleWin with extended debug features.

Now you can monitor any given text/graphic page in addition to the regular cycle-accurate emulator output!



Real-time monitoring of multiple graphic pages in AppleWin.

We started to add some experimental features to the amazing debugger bundled in AppleWin!

Starting with realtime disassembly and live memory heatmap.


Last blitter record on Atari STE : 23 sprites of 32x32, 4 bitplanes. At the same 320x200 resolution and with help from the CPU, the Amiga blitter can display 24 sprites.

When pushing the display area to 320x256 (with overscan on STE),the STE should stay at 23, while the Amiga slows down to 22.

However in any case the Amiga can also add two 32x32 hardware sprites.

This was achieved by optimizing the blitter calls and masking on STE.

Rewrote my FYM player for Apple II.

I put it on github last week and found out that the code was really crap (two days ago I just started to do 6502 code).

-25% CPU time 😈

Les modes vidéo chelous de l'Apple II

Petites recherches avec Grouik/FT sur quelques "modes" d'affichage peu connus de cette machine... qui sont plus souvent des effets collatéraux de son architecture.

Le tout saupoudré de modes DHGR.

I finally put the source of Bad Apple for Atari STE on github. The original archive didn't contain any build instructions 😅



Excellente interview de Raphaël Gesqua, compositeur de cinéma et de jeux vidéo (Flashback, Mr Nutz, Fade to Black... récemment Toki).

aka "Audiomonster" dans la Amiga des années 1990 (avec des images d'archive ❤️)

Cette démo est un palindrome : jouez-là à l'endroit ou à l'envers, vous obtiendrez la même chose... y compris la musique.

⚠️ CW épilepsie - elle contient de nombreux effets stroboscopiques.

Je l'utilisais pour tester la résilience des codecs vidéo !

As a member of French touch, I must now code a mandatory never-seen Apple 2 effect every month

(just kidding, it's not mandatory, I do it for fun)

Great basic effects live coding on PICO-8 by Jori Kemppi!

Good explanations and clear code :)

54:00 3D Cube

With improved hardware compatibility check during boot time.

The boot sequence now takes 2 sectors, but who cares, the floppy disk is 80% empty.

Also the fastload routs are loaded by the boot ROM.

Trackloader version of Latecomer, thanks to Grouik/French Touch's tools and routines.

Now loads in 7s on my Apple II

(instead of 21s for the ProDOS version)
