Furrtek @furrtek.bsky.social · 09/09/2026Solution trouvée mais il faut attendre malheureusement, des cartouches de jeux ne font pas le poids devant les besoins de l'IA et des constructeurs de bagnoles. 110
Furrtek @furrtek.bsky.social · 05/09/2026Kind of surreal to see an SNK branded chip with a 2026 datecode 2270
Furrtek @furrtek.bsky.social · 04/09/2026NEO-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. 1294
Furrtek @furrtek.bsky.social · 22/08/2026Sinon pas besoin d'une conv pour se voir, mais le vrai problème c'est que je sors de mon terrier environ 3 fois par an 110
Furrtek @furrtek.bsky.social · 22/08/2026Perso j'ai toujours passé un bon moment. Le changement d'hotel a refroidi pas mal de monde malheureusement (tarif, séparation hotel/convention center). Les choix des dernières années ont été durs, ça fait de la peine pour l'orga car ils se donnent du mal. 100
Furrtek @furrtek.bsky.social · 22/08/2026Tu rates pas grand chose :) Je fais toujours la FBL cette année, si t'es à Paris fin Octobre 100
Furrtek @furrtek.bsky.social · 22/08/2026Freshly 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 07611
Furrtek @furrtek.bsky.social · 20/08/2026Nul part à vrai dire, j'ai été à quelques furbars et à la FBL mais je m'y retrouve plus, écart d'âge et d'intérêts 100
Furrtek @furrtek.bsky.social · 15/08/2026Pretty sure the 055550 is from Epson, markings and "SLA" prefix match. 100
Furrtek @furrtek.bsky.social · 15/08/2026Very rare silicon speed limit for when signals are too fast 0444
Furrtek @furrtek.bsky.social · 15/08/2026Mayan symbols in Nintendo MMC5 Possibly just a resistor to ground drawn by a layout artist who had one too many 1293
Furrtek @furrtek.bsky.social · 02/08/2026Simpler if you're talking of custom boards, doesn't need to fit the original chip footprint. But still: if you aren't making 100's, $20 FPGA, $15 flash, $10 shifters & passives, $10 PCB, assembly, shipping and taxes and there isn't much left. Many who try physical releases realize that too late. 130
Furrtek @furrtek.bsky.social · 02/08/2026I doubt repros will be made, wouldn't be economically viable given an FPGA, level shifters and an interposer board would be required 110

Furrtek @furrtek.bsky.social · 11/07/2026Franchement, peut mieux faire. Mes objectifs sont malheureusement de piètre qualité. 110
Furrtek @furrtek.bsky.social · 11/07/2026And finally the most visually interesting ones: NEO-YSA2 with its CMOS YM2610 equivalent and synthesized Z80, and NMK-215, a microcontroller who @recreativospiscis.bsky.social made a dumper for siliconprawn.org/map/snk/neo-... siliconprawn.org/map/nmk/nmk-... 3/3 1241
Furrtek @furrtek.bsky.social · 11/07/2026Then VS9209, VS920A, VS8905, VS8803 from Video System, gate arrays too, some with RAM blocks siliconprawn.org/map/videosys... siliconprawn.org/map/videosys... siliconprawn.org/map/videosys... siliconprawn.org/map/videosys... 2/3 1240

Furrtek @furrtek.bsky.social · 07/07/2026Aw Digikey made a little H with my MCUs. Is it for "Help" ? 0160
Furrtek @furrtek.bsky.social · 28/06/2026Their documentation isn't clear about that and the type name does sound like only inputs are supported. However given their reply and the very low leakage current measured I'm pretty confident 5V is safe on inouts, as long as they're not fighting of course. 230
Furrtek @furrtek.bsky.social · 28/06/2026Lattice support told me all 4000ZE IOs are technically 5V tolerant as long as the bank's VCCO is 3.3V, the *_5V IO types are a hint for the auto pin assignation to group them in the same banks. 130
Furrtek @furrtek.bsky.social · 28/06/2026They should have been ready for june, sorry. I still haven't adopted the new standard of getting things out the door as cheaply and quickly as possible by collecting other's free help and vibecoding what's missing. 3210
Furrtek @furrtek.bsky.social · 28/06/2026Neo CD SD Loader V2 final prototypes for CDZ, top and front loaders are finally validated 5314
Furrtek @furrtek.bsky.social · 10/06/2026Thought I knew Fujitsu gate arrays well enough to not be bitten by such things, but I was wrong. Inputs can be inverting. 0231
Furrtek @furrtek.bsky.social · 06/06/2026TL;DR: Used negation instead of XOR, fails if checksum is 0 130
Furrtek @furrtek.bsky.social · 05/06/2026With @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 35311
