4464461. Remove the custom QFP144 CPU and replace it with a standard Hitachi HD6417095 SH-2 CPU
4474472. Remove the 29F400 TSOP48 flashROM and re-program it with the decrypted and modified main program ROM from set
448   'cps3nobatt' in MAME. A 28F400 SOP44 flashROM can be used instead and mounted to the back side of the security cart
448   'cps3boot' in MAME. A 28F400 SOP44 flashROM can be used instead and mounted to the back side of the security cart
449449   PCB. Do not mount both SOP44 and TSOP48 flashROMs, use only one TSOP48 flashROM or one SOP44 flashROM.
4504503. Power on the PCB and using the built-in cart flashROM menu re-program the SIMMs for your chosen game using the CD
451   from set 'cps3nobatt' in MAME.
451   from set 'cps3boot' in MAME.
4524524. That is all. Enjoy your working PCB.
