Hello!
I've got two files with dumps from the two eproms of an SHVC-4P5B-01 board. How can I prepare these files to use with an emulator?

Thanks in advance!

Just combine both into one signle file and that's it - no header, the emulators should be able to read the internal header, and they will automatically use LoROM or HiROM depending on where you place the header (I belive it's at $00:7FF0 for LoROM and $00:FFFF0 for HiROM).
Some SNES ROMs have a 512-byte header, but I guess it's useless and have no purpose, I'm not too sure though. Maybe it's used for games which uses special mappers ?

The internal "header" should be at the correct offset already in those dumps.
The extra 512-byte header is useless except if you're planning to play the ROM on a Super Wild Card or some other floppy-based copier, so there's no need to add it.

Mh, i can't get it to work. Maybe someone take a look at this two files?

You've got a bad/overdump there. I know because I'm the one who currently owns the prototype board you mentioned.

It's actually a prototype ROM called "Buck Rogers - The Arcade Game", which was later enhanced with scrolling backgrounds and finally released as "Jim Power - The Lost Dimension 3D".

I'm going to contact Evan G, who runs snescentral.com, and provide him with some more info soon so he might write up an article about it.

Ah, maybe you are the one who bought it this year from on ebay!?

That's great after i sold it, i realized that it must be Jim Powers - but without this confusing background scrolling Are you sure that this is a proto and not even a hack of Jim Powers?
