This chipset is under a metal
heat sink on the cartridge
printed circuit board (PCB) however initial shipments of the cartridge had reports that the heat sink was improperly secured onto the PCB, with WaterMelon releasing a statement in the game's online support page that users should open up their cartridge case and remove the heat sink to not damage the PCB, as the heat sink is purely for aesthetics and not needed for function.
[35] Users that have removed the heatsink found
epoxy covering the DATENMEISTER chipset, put there by WaterMelon to prevent chipset
reverse engineering.
[36][37] Removing the epoxy reveals several additional chips such as an
Altera FPGA (10M02SCU169C8G), a
STMicroelectronics microcontroller (STM32F446ZEJ6), a
Spansion microcontroller (GL064N90FFIS2), an
ISSI semiconductor RAM (IS42S16100H), and two
logic gates from
ON Semiconductor (74LCX245 and 74LCX257),
[38] which is used to handle the additional audio channels and capability, and to assist the console in various game tasks (managing VRAM, generating sprite table...)
