The game "SD Gundam Gaiden - Knight Gundam Monogatari 2: Hikari no Kishi" (PRG-ROM CRC 73AC76DB) is listed on NesCartDB as using an X24C02P (256-byte serial EEPROM), but the game's code interacts with it as if it were an X24C01P (128-byte serial EEPROM). The game claims to have two (128-byte) save slots, and the game even calls its "read from EEPROM" ($08:$9CEC) and "write to EEPROM" ($08:$9D22) routines with addresses greater than 128, only to have the upper bit get masked off (to replace it with the R/W bit) - as a result, both save slots always contain the same data. Is this for real, or am I losing my mind? --Quietust (talk) 09:41, 20 May 2020 (MDT)
