Prepare ROM file for write to EPROM Using HEX editor:

Open ROM with any HEX editor software and mark first 16bytes header

Then CUT marked 16bytes header

Now file have 524288 bytes, if ROM have ONLY 512KB PRG ROM and doesent have CHR ROM, then this file is READY for write to EPROM/FLASH. If not, you must SPLIT file into two parts (first 256KB and second 256KB)

SNES ROM's have 512byte HEADERs

SPLIT ROM FILE USING WINDOWS COMMANDER (TOTAL COMMANDER) 256KB NES ROM Example - 128KB PRG & 128KB CHR:

Mark ROM file and select "SPLIT" option from "FILES" menu

Then set file size number (for this example set "128 kb" - this option make two 131072 byte files)

Now rename xxxx.001 and xxxx.002 files into xxxx001.bin and xxxx002.bin (this two files is READY for write to EPROM/FLASH)

Using WINDOWS (TOTAL) COMMANDER you can also prepare SNES ROM's. How to split 4MB ROM: first remove header (you mus have 4194304 bytes file), then set "1024 kb" in split file window for make four 1048576 byte files (ready for write to four 27C801 EPROMS)

PREPARE SNES ROM FILE USING SNES-TOOL:

Before prepare, try FIX ROM file with "SLOW ROM FIX" if you have slow EPROMS than 120NS (all 150ns, 200ns chips) and use REGION FIX like "fix for PAL" or "fix for NTSC" (for best results try ask on many FORUMS (discussion boards) which one ROM regire which type of FIX)

Select "Delete header" option and select ROM file and do it

Select "Split" option and select ROM file and set size of split (if you want write ROM into 512KB 27C040 EPROMS then set "Mbit 04" if you want use 27C801 EPROMS the set "Mbit 08"

Now you must once more select "Delete header" option and select first xxxxx .1 file (this will delete headers from splittet files

Now you have Ready for write to EPROMS four 1048576 byte files

ROM file sizes (without any headers)
