An easy to use utility for performing some tasks on SNES / SFC ROMs!
Change basic header information like title, country/region, version and game code.
Adds an empty header.
Removes an existing header.
Fixes a broken checksum. You always should do this before saving, if possible. Please note that some beta or demo ROMs have an odd checksum anyway...
Fixes wrong internal ROM size information. Do this after expanding a ROM. Also useful to fix some ROM hacks.
Expands ROM to a specific size up to 64 Mbit (BS-X up to 32 Mbit). Mirror option should only be used, when there are problems with standard expanding. Always check if your ROM still works after doing this!
Splits ROM into equal sized multiple parts.
Swaps binaries to get a "Close-to-SNES-Mask-ROM"-layout.
Use 27C801 (E)EPROM and rewire pins as followed:
27C801 | Nintendo Mask ROM |
---|---|
24 | 31 |
31 | 24 |
Some copy stations like "Game Doctor SF" or "Super UFO" use interleaving when dumping HiROM games. This function will reverse this process. Please use ROMs with copy station header, unless you know which copy station was used!
Some patches or copy stations require interleaved HiROMs. This function will interleave your HiROM. If you have interleaved a ROM, patched it and want to play it in an emulator, flashcard or make a physical copy, don't forget to deinterleave and fix checksum again!
Note
Only HiROMs can be interleaved!
Some games have a copy protection preventing the ROM from running on systems with another region (PAL/NTSC lock). Use this function to remove most known region locks.
Some games have a copy protection preventing the ROM from running, when cartridges have more SRAM than needed (copy stations/some cheap flashcards/deprecated emulators). Use this function to remove most known SRAM checks.
Useful if you want to play your FastROM on a copy station without FastROM support or make a physical copy using an (E)EPROM/FlashROM slower than 120ns.
Can switch ROM layout between HiROM and LoROM. If the ROM uses (S)RAM or some enhancement chips, you have to do some manual work after conversion.
Note
Converting from HiROM to LoROM only works, if the ROM was designed to be convertible
Patch your loaded ROM!
- IPS
- RLE hunks
- truncating
- avoids EOF offset bug
- UPS
- revert a patch, if applied a second time
- BPS
- BDF
- XDELTA
Note
If you have a BDF patch file with .bdiff extension, try to change this into .bdf
Also try renaming XDELTA patches ending to .vcdiff into .xdelta
- Scan/Rescan ROM for copy protections.
- Miror ROM on expanding
- Checked
- ROMs' content gets mirrored when it gets expanded
- Unchecked
- Standard expanding will be perfomed to get more space available
- Checked
- Scan protections on loading
- Checked
- ROM will be scanned instantly for copy protections on loading. This might take a few seconds
- Unchecked
- You have to manually click the Scan button to check for copy protections
- Checked
- Use Windows Commandline (CMD) for executing batch operations (or just for processing a single file, if you prefer using the commandline)
- Build your own command chain to execute operations in the order you specified!
Note
Deinterleaving and interleaving might require user action! This will bring up a windows form and can only work within a Windows environment!
Example:
Advanced_SNES_ROM_Utility.exe -path "C:\ROMs" -recursive -header add -patch "C:\Patches\patch.ips" -header remove -fixromsize -fixchecksum
This command will add a header to all ROMs in C:\ROMs (subfolders included), apply an IPS patch, remove header afterwards, fix internal ROM size and checksum and save the modfied file with an extension.
For more information type
Advanced_SNES_ROM_Utility.exe -help
or take a look into the tool's manual.
- checksum doesn’t include header information (it won't change if you edit values)
- There's no region code (JP only)
- ROM size is limited to a maximum of 32 Mbit
