Kind of surreal to see an SNK branded chip with a 2026 datecode

Furrtek @furrtek.bsky.social · 04/09/2026

NEO-PCM2 curiosity: MAME has pcm2_prot_device::swap which applies a XOR to decrypt the data of some games. Problem: I can't see a path for a XOR to be applied on data in the real chip. If SNK made different NEO-PCM2's to confuse pirates, they're bastards and I love them.

Freshly decapped and scanned NEO-PCM2: ADPCM ROM multiplexing and security used by late NeoGeo games. Hopefully will help fix inexact descrambling emulation. Fujitsu CG47 gate array from 1999 Kindly donated by @Rolel42

Thought I knew Fujitsu gate arrays well enough to not be bitten by such things, but I was wrong. Inputs can be inverting.

With @modernvintagegamer.com's video about Doom on the NeoGeo, I think it's a good time to share an old and very silly project related to putting gory stuff in a cartridge and using the console as a video pass-through: www.furrtek.org?a=superngpc In 🇫🇷 but any autotranslate works well enough

If you need a Neo CD SD loader and can wait until june of this year, don't buy one from Aliexpress, you'll regret it.

I get the escapism thing, but outside of the internet I'm feeling more and more surrounded by external hard drives filled with mass media, and it kind of sucks. Being more interested in raw reality than Netflix and Steam often makes me feel I don't belong here.

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.

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 ?
