Metamorphic Force OST, digital audio straight from the real 054539's drive.google.com/drive/folder...

What's wrong Konami ? You haven't even touched your top 5 bits. This is before the final digital volume control so ideally it should be max amplitude. Feeling like I'm missing something.

Pairs of registers defining the speed and amplitude of a triangle waveform generator, which is used as an offset from the reverb buffer's tail: Heavy suspicion of an unemulated flanger effect in the Konami 054539.

"The 054539 is quite complicated, maybe making a data flow diagram will help me understand how things are supposed to work" ...sheeeeeeit

L'unique chose qui m'ennuie avec le fait de vieillir dans une société flippée, c'est que quand j'étais gamin et que je regardais les techs France Telecom bosser dans la rue, ça amusait les gens. Maintenant ça va chercher les flics. C'est dur d'exister parfois.

I/Q of radio frame. Obviously PSK, but what's with the noise ? It occurs at the same points while the frame is repeated. Can something on the receiver side cause this ?

Details to be confirmed, but the scoring control of Buzz Lightyear Laser Blast ride (and probably the other versions) is very weird, feels like it was designed by mechanical engineers forced to do EE. It's a very unintuitive mix of IR and outdated ISM radio.

All NeoGeo repro chips were transferred to my website's shop: www.furrtek.org/shop/ Please let me know here or by e-mail if you have any issues.

Updated the RE'd Fujitsu AV gate array cell library. It's now 73% complete. github.com/furrtek/Sili...

Released a Python tool to extract samples from NeoGeo V ROM files by manually setting start/stop points: github.com/neogeodev/Ne... Useful to get clean samples without BGM and to find possibly unused content 1/2 🧵

NaluaStudio's Vengeance Hunters seems to be a customized Neo SD cart. Anyone able to confirm ?

The Basement Brothers have discovered an error that went undetected for years in my Fusion AES to MVS converter ! It affects indie/homebrew releases only. Fixing it allows Super Bubble Pop, and NG:DT's Neo Xyx, Gunlord and Razion to work. The Neo SD Pro still isn't happy. 1/4

¯\_(ツ)_/¯

Completed the reverse-engineering of the Konami 053936 "3D" plane generator chip used by a bunch of GX games, which had several undocumented settings. One thing less to do ! github.com/furrtek/Sili...

Konami Open Golf Championship "voxel" terrain height data. I'd work on the rendering chip if more games used it, and if I didn't swear 2025 was a finish-things-don't-start-anything-new year.

Published my Sharp gate array reverse-engineered cell library. JPGs are mugshots, PNGs are layout with IO locations and names: github.com/furrtek/Sili...

Selling Konami chips that I already have to recoup cost of a working sacrificial GX board: 2x 054539, 054338, 056879, 056766, 053246A, 054156, 055555 and 68EC020 CPU. All in perfect shape, ready to be used for repairs. 9€ each. 4€ tracked intl shipping for any number. PayPal only.

2025 will be my first "less time in Inkscape, more time in Scribus" year (Also less time on garbage X)

HackRF TRF37B73 TX amp transplant is a success. Hopefully this one won't be as fragile.

L'algo pour vérifier le caractère de contrôle sur les numéros de suivi 15 chiffres La Poste est connu ? Je trouve rien et légère flemme de creuser dans l'appli Android.

Went through a few more dies in the waiting line: Konami 053246: Sprites controller siliconpr0n.org/map/konami/0... Konami 053244A: Sprites controller siliconpr0n.org/map/konami/0... Namco 117: MMU siliconpr0n.org/map/namco/11... 1/3

Why I dislike tracing Toshiba gate arrays episode 57: This is an adder. It adds an 8 bit number with a 24 bit one. That's it. Nothing else.

Uploaded some new die shots: Konami 055555 layer mixer with alpha (and free hair) siliconpr0n.org/map/konami/0... Konami 055550 DMA/protection siliconpr0n.org/map/konami/0... Konami 056766 color processing and RGB DAC siliconpr0n.org/map/konami/0... 1/3

Help wanted for datasheet hunting ! Markings: Sunplus PU5165 Bonded pads: 43/44 Fully digital, no memory, very small, uses a 455kHz oscillator, suspected IO expander
