Upgraded from a single 256gb to a single 512mb. This guy worked now rhythm heaven is playable!!!

Rhythm Tengoku is one of my favorite games on the system. So worth the upgrade.

Can someone let me know if these will work? https://www.nmutu.com/archive/new-S...ch-Pc100-256meg-998-0217/sku393456148785.html

Thought I'd add my 2 cents. Pulled these two sticks from an old PC:
ELPIDA SINGAPORE MC-4532C0647XFA-A75
My Naomi 2 doesn't seem to have an issue with them.

Originally, it only had one stick of Hynix HY57V28820HCT-H.
