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 ?

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It's a very unintuitive mix of IR and outdated ISM radio.

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

Completed the reverse-engineering of the Konami 053936 "3D" plane generator chip used by a bunch of GX games, which had several undocumented settings.

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.
