PS1 scph-1000 bios mod question

[phaseas]

i do own a scph-1000, the first jap model

i was wondering if it would be possible to remove its bios and place a "DTL-H1001" bios instead
and if so, how to proceed

perhaps there is some eeprom i can just dump DTL-H1001 and solder?

im assuming DTL-H1001 would be compatible but i could be wrong

anyone with experience in this field?

help / ideas will be appreciated

thanks
