CPS2 EEprom Programming Question

[DarthMig]

Hope somebody can answer this question for me. Prob a stupid questions. I look through the forum and did not find anything about this.

So i have a Street Fighter Zero 2 Alpha (orange) board that was pheonixed/avalaunched. I want to bring back to original roms with a infinikey. I noticed that it is populated with eeproms (sockets) from spots 1-8.

When i look at the files sfz2alh which i got from a pack i use with my cps2 multi there are more files. They go from flash.01 to flash.12. (flash.04 is not used) Do i just flash each one of this files to a eeprom and put into its corresponding socket on the b-board or is there something else i have to do.

Some help would be appreciated.

You need to use the original rom bin files, not the files prepared for use with a multi. Look for the mame release of that game...
sfz2alh Street Fighter Zero 2 Alpha (Hispanic 960813)

Double check the ROMs you find against the mame CRCs
https://github.com/mamedev/mame/blob/master/src/mame/drivers/cps2.cpp

ROM_START( sfz2alh )
	ROM_REGION( CODE_SIZE, "maincpu", 0 )      /* 68000 code */
	ROM_LOAD16_WORD_SWAP( "szah.03", 0x000000, 0x80000, CRC(06f93d1d) SHA1(495de176ba55b35270fc05f19edf17a0f249ff0e) )
	ROM_LOAD16_WORD_SWAP( "szah.04", 0x080000, 0x80000, CRC(e62ee914) SHA1(def4f27c1b64be5143234f1f402260adae66cdde) )
	ROM_LOAD16_WORD_SWAP( "szah.05", 0x100000, 0x80000, CRC(2b7f4b20) SHA1(5511263f5f6e532ee7fe1995f08f16651a1d45a1) )
	ROM_LOAD16_WORD_SWAP( "sza.06",  0x180000, 0x80000, CRC(0abda2fc) SHA1(830da40f6a9bb3bc866ee9c5cab1b0eb3c4dcb71) )
	ROM_LOAD16_WORD_SWAP( "sza.07",  0x200000, 0x80000, CRC(e9430762) SHA1(923aea8db5f9b59212ec6dbc35be0808ea015140) )
	ROM_LOAD16_WORD_SWAP( "sza.08",  0x280000, 0x80000, CRC(b65711a9) SHA1(3918f44e1bb189e2a115625b35f477eb91a65f04) )

then take only the program roms from the zip and burn those to blank eproms. Then you can do the infinikey as normal.

I just went through this process 2 days ago on a ssf2u... except I chose to install a battery.
