Hey guys, I'm trying to repair a Naomi game cartridge for my friend. We only get a black screen when cart is inserted. One of the LCX16373 chips (16 bit latch) was getting extremely hot I replaced it. Still no joy. Checked the EPROM, it didn't checked with romident so I re-programmed it. Still black screen. My next guess is to check the flash looking mask roms on the game cart but I do not know how to read them and what would be their replacement flash chips?
The reading on the mask roms are MX28L12811TC. The datasheet says it is a 128Mbit Mask ROM operating at 3.0-3.6V in TSOP48 package
Does anybody know what would be replacement for this? If any pin compatible replacement exists?
