Tom Henderson reports that Ubisoft's internal communication channels are flooded with employees openly shaming upper management and demanding serious change.
The latest restructuring was the breaking point after years of mismanagement.
Talent is already leaving in large numbers, even before the next round of layoffs begins.
The company is rotting from the inside while leadership remains oblivious.

First Kickstarter I've been excited about for a while! Interviews with 32 C64 game devs including some of the earliest, like the HAL Laboratory guys. I've disassembled a lot of their code over the years, so I feel like I know them!

Sega Genesis Blast Processing MAXED OUT ???
Whats better than 660 sprites in 660 colors (prev demo) ???
1013 sprites in 1013 colors !!!
Demo starts at 117 sprites then adds 20 sprites per second every second until it reaches Max Blast Processing at ~ 46 seconds mark.
Live Sprite/Color Counter top left , updates periodically.
Thanks to @Carsten1349 for amazing artwork and @laurent_crouzet for pumping audio (a Lufthoheit team collaboration) - appreciate your support guys !!
Snippets:
18 Hardware sprites multiplexed 56x each (max level) = 1008 sprites + 5 player ships = 1013.
4-5 colors changed by DMA every scanline.
Repositioning 4.5 sprites every scanline - this is VDP maximum level for X&Y (more sprites onscreen with color change is not possible unless I find a miracle).
Ran out of total palette colors near mid screen, Shadow & Highlight mode enabled to shadow more colors from that point.
Shown on Hardware MD 1 VA 6 + PVM.
Coding was a REAL headache, it uses ~ 97% of the cpu/dma time and timing is very tight.
Took 3 days alone just to get the music to play - PCM was taking up too much cpu (little cpu to spare). XGM2 sound driver helped & lowered cpu cost, thanks @MegadriveDev
Sprites are moved independently at 18 different speeds and their distribution was tricky.
Background Planes A & B used for spinning Galaxies.

I want to give a special shout-out to @AstridOosenbrug for being one of the reasons I can do what I do here in The #Netherlands
She kickstarted the political climate where security researchers are applauded instead of prosecuted and now leads @DIVDAcademy. Legend. ❤️

Hiervan brak toch even onze klomp.
🫤 Er is een mega bekritiseerd wetsvoorstel dat de vertrouwelijkheid van onze communicatie zou ondermijnen.
🫨 De EU maakt daar reclame voor.
😵💫 Die wordt met behulp van de surveillance advertentie industrie verspreid.
Hallo hè.

Help!
Trying to determine the access speed for ROM cartridges on the #Sega #Megadrive #Genesis. Kinda hard if you only have one cartridge (Sonic), but that's what I have to work with now.
The CE line for ROM does not go low (active) is AS is not low, meaning, I can only see 68000 accesses. However, the not-so-confidential-any-more 120-page "Sega Technical Overview 1.00" document clearly says that DMA from ROM to RAM is possible. It seems like Sonic is not making use of that DMA mode.
This logic analyzer shot shows a DMA burst that happens during VBlank: I see OE cycling, but CE is high, so this is most likely a RAM-to-RAM transfer, or a RAM-fill burst.
Is there a game or scene demo that I can write to a ROM-only cart that makes use of ROM-to-RAM DMA transfers? I have PCBs coming in that will let me make 2MByte ROM-only carts, and "the right binary" would be highly appreciated.

We hebben Fox-IT gevraagd om forensisch onderzoek te verrichten in onze systemen. Dit naar aanleiding van de aanhouding van een van de vrijwilligers op verdenking van cybercriminaliteit.
