In some designs, 78081g503 corresponds to a on a board (e.g., a CPLD or FPGA). The error “not found” means the system cannot detect that chip via I2C, SPI, or the system bus. This could be due to a loose connection, cold solder joint, or dead chip.
: As of recent emulation records, this specific BIOS file has been flagged as "not dumped," meaning the data has not yet been successfully extracted from the physical chip and converted into a digital format for use in emulators like ROM Errors 78081g503.ic655 not found
If you are trying to run games like Street Fighter EX2 Plus (Japan) or other ZN-1/ZN-2 titles, MAME checks for this file as part of the machine's required startup sequence. Because it is often missing or undumped, the emulator will report a and refuse to launch the game. Potential Solutions In some designs, 78081g503 corresponds to a on a board (e
